Appeals from the United States District Court for the Eastern District of Louisiana.

Before VAN GRAAFEILAND, * * KING, and EMILIO M. GARZA, Circuit Judges.

KING, Circuit Jue:

Plaintiff–Appellant Employ ers Insurance of Wausau ("Wausau"), in its own right and as

representative of certain American Underwriters, 1 filed a cross-claim against Plaintiff–Appellee

Occidental Petroleum Corporati on ("Occidental"), seeking to recover ma rine insurance policy

proceeds paid to Occidental in 1982 under a reservation of rights. Occidental moved for summary

judgment. The district court granted the motion and dismissed Wausau's cross-claim with prejudice.

Wausau now appeals the district court's order granting summary judgment. For the following

reasons, we affirm the judgment of the district court.2 The Oxy Producer ITB was a catamaran integrated tug barge vessel. According to Wausau,

such vessels are composed of a tug and a barge that are "mated" through an interconnection

system. Thus, the Oxy Producer ITB consisted of the Oxy Producer (the tug) and the Oxy 4102

(the barge). I. BACKGROUND

This insurance dispute arises from the sinking of the Oxy Producer, the tug unit of the Oxy

Producer ITB, 2 on September 20, 1981. Events occurring before and after this date, however, are

relevant to our disposition of the case. Accordingly, we recount the events leading up to and

following the sinking of the Oxy Producer.

A. Events Preceding the Sinking of the Oxy Producer

After agreeing to manufacture, sell, and transport superphosphoric acid to the Soviet Union

in the early 1970's, Occidental arranged for the construction of three catamaran ITBs. Numerous

part ies were involved in the construction project. Occidental first retained Hvide Marine

International, Inc. ("Hvide") to supervise the design and construction of the vessels. Hvide, in turn,

contracted with a naval architectural firm, J.J. Henry Co. ("Henry"), to prepare the plans and

specifications for the vessels. After Hvide assigned the architectural contract with Henry to

Occidental, Occidental engaged Avondale Shipyards, Inc. ("Avondale") to construct the vessels.

Avondale thereafter subcontracted with Victoria Machine Works, Inc. ("Victoria") to manufacture

the bumper pads for the vessels' catug interconnection system.

Before construction of the three ITBs was finished, Occidental and Hvide obtained insurance

for the vessels in the American and London markets. The unit of the vessel at issue in this case, the

Oxy Producer, was insured under Certificate No. 14880, a time policy of hull and machinery

insurance. The policy was to become effective on the date that the Oxy Producer ITB was delivered.

The agreed-upon

value of the Oxy Producer under this policy was $36,000,000. The American

Underwriters, primarily through Wausau, subscribed to 28% of the risk under the policy.

B. Events Surrounding the Sinking of the Oxy Producer

The Oxy Producer ITB was delivered to Occidental on June 9, 1981, and thereafter made one

successful trip to the Soviet Union. However, on its second trip to the Soviet Union—in September3 For a more detailed description of the events leading up to the sinking of the Oxy Producer,

see Employers Insurance of Wausau v. Suw annee River Spa Lines, Inc., 866 F.2d 752, 756 (5th

Cir.), cert. denied, 493 U.S. 820, 110 S.Ct. 77, 107 L.Ed.2d 43 (1989).

4 The London Underwriters were not a party to the Standstill Agreement because they had, by

this time, already waived their reservation of policy defenses.

5 One of the reasons that Occidental wanted to enter into the Standstill Agreement, according

to Wausau, is because Occidental previously had agreed to indemnify Hvide for claims arising out 1981—the Oxy Producer ITB ran into rough weather, which caused substantial movement between

the Oxy Producer (the tug unit of the vessel) and the Oxy 4102 (the barge unit of the vessel).

Ultimately, the movement of the barge unit against the Oxy Producer opened holes in the hulls of the

tug and caused it to sink. 3

C. Events Surrounding the First Lawsuit

Sh o rtly after the Oxy Producer sank, Wausau, on behalf of the American and London

Underwriters, began investigating the loss. When the investigation moved too slowly for Occidental,

it pressured the underwriters to pay the claim. To avoid jeopardizing any subrogation rights through

litigation with the insured, the underwriters decided to pay the claim—but only under a reservation

of all policy defenses.

After the underwriters paid the claim under the time hull insurance policy, they and Occidental

filed suit against the var io us parties involved in constructing the Oxy Producer ITB. The

underwriters and Occidental argued that Henry was liable for the loss because of its role in preparing

the plans and specifications for the vessel. Avondale was liable, the underwrit ers and Occidental

contended, for not following the a rchit ect ural plans and for using defective bumper pads in

constructing the vessel. Because it supplied the allegedly defective bumper pads, Victoria was also

named as a defendant. And finally, the underwriters and Occidental sued Hvide fo r its role in

supervising the construction of the Oxy Producer ITB.

On July 23, 1984, almost two year s aft er the sinking of the Oxy Producer, Occidental, the

American Underwriters, and Hvide executed a "Standstill Agreement." 4 The general purpose of this

agreement is undisputed: it was t o allo w Occidental, the American Underwriters, and Hvide to

present a united front against Henry, Avondale, and Victoria in the already pending lawsui t

. 5 Theof Hvide's operation of the vessel. In its brief on appeal Wausau states: "Occidental expressed

concern [at the time the Standstill Agreement was executed] that it would, in effect, lose its

recovery for the OXY PRODUCER in the event of any negligence of Hvide by operation of the

indemnity agreement."

6 Although the district court found that Avondale had been negligent in performing its

construction contract, the court also found that the contract effectively disclaimed tort liability. agreement limited the types of claims that would be advanced in the pending action against Henry,

Avondale, Victoria, and Hvide. The agreement also discussed the types of claims that could be

asserted among the three parties in a subsequent action. The meaning and effect of the agreement

on the latter subject, however, is the subject of considerable dispute. See infra Part III.

The lawsuit against Henry, Avondale, Victoria, and Hvide finally proceeded to trial in 1986.

After a three-month bench trial on the issue of liabilit y, the district court concluded that the sinking

of the Oxy Producer was caused solely by improper mating of the vessel and that therefore the vessel

was unseaworthy on delivery. The only parties found liable for the improper mating were Avondale

and Hvide. The district court found that Avondale was negligent in performing its construction

contract 6 and that Avondale had breached the contract and its express warranty of seaworthiness.

Hvide, according to the district court, had breached its supervision agreement with Occidental, had

breached its warranty that the plans fo r the vessel would assure its seaworthiness, and finally, had

been negligent in supervising the mating of the vessel. Both Henry and Victoria were dismissed from

the suit, because the district court found that they were in no way responsible for the improper mating

of the vessel.

On appeal of the first lawsuit, we affirmed the district court's holdings that the vessel was

improperly mated and unseaworthy on delivery and that this condition alone caused the Oxy Producer

to sink. We reversed the district court's dismissal of claims against Henry and Victoria, however, as

being premature. Finally, we remanded the case for a determination of damages in a manner

consistent with our opinion. S ee Employers Ins. of Wausau v. Suwannee River Spa Lines, Inc., 866

F.2d 752, 755 (5th Cir.), cert. denied, 493 U.S. 820, 110 S.Ct. 77, 107 L.Ed.2d 43 (1989).

D. Wausau's Cross–Claim for the Return of Insurance Proceeds

On remand, Wausau filed a cross-claim against Oc cident al o n behalf of the AmericanUnderwriters, seeking recovery of the proceeds paid to Occidental under a reservation of rights. In

this cross-claim, Wausau asserted that, because the Oxy Producer ITB was unseaworthy at delivery,

Occidental breached the warranty of seaworthiness implied at the inception of the time hull policy.

Wausau reasoned that Occidental's breach of the implied warranty of seaworthiness at the inception

of risk preve nt ed t he time hull policy, under which Occidental had claimed the proceeds, from

attaching.

Occidental moved for summary judgment, asserti ng t hat there were no genuine issues of

material fact and that Wausau's cross-claim was barred as a matter of law. In support of its motion,

Occidental advanced numero us arguments. Occidental first argued that the Standstill Agreement

between Occidental, Hvide, and Wausau expressly precludes the cross-claim. Occident al also

contended that, under a time hull policy like the one issued to Occidental, there is no absolute implied

warranty of seaworthiness at the inception of coverage. Occidental further maintained that, even if

there is such an absolute warranty implied at the inception of coverage, its particular ti me hull

policy—through the Liner Negligence Clause and the Separate Policy of Insurance Treatment

Clause—nonetheless provides coverage for the loss incurred in t his case. Occidental finally argued

that Wausau and the American Underwriters had waived or are estopped from asserting their right

to seek recovery of the insurance proceeds.

The district court agreed with at least three of Occidental's arguments, and therefore granted

summary judgment in Occidental's favor. As one ground for granting summary judgment, the district

court relied on the "clear and unambiguous" language of the Standstill Agreement, which it held bars

Wausau's cross-claim as a matter of law. The district court also held that the Liner Negligence Clause

in the insurance policy supported summary judgment in Occidental's favor. In particular, the district

court reasoned that the due diligence provision in the Liner Negligence Clause displaces any implied

warranty of seaworthiness at the inception of risk. As a third ground for granting summary judgment,

the district court cited the Separate Policy of Insurance Treatmen t Clause in the insurance policy.

This clause, in the district court's view, provides an additional basis for coverage of Occidental's loss.

Wa usau t hereafter filed a timely notice of appeal from the district court's order granting summaryjudgment in favor of Occidental.

II. STANDARD AND SCOPE OF REVIEW

In reviewing a summary judgment, we apply the same standard as the district court. W altman

v

. International Paper Co., 875 F.2d 468, 474 (5th Cir.1989). We ask specifically whet her "t he

pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits,

if any, show that there is no genuine issue as to any material fact and that the moving party is entitled

to a judgment as a matter of law." FED.R.CIV.P. 56(c). In answering the first part of this question,

we view all evidence and the inferences to be drawn from the evidence in the light most favorable to

the party opposi ng the m oti on. M arshall v. Victoria Transp. Co., 603 F.2d 1122, 1123 (5th

Cir.1979) (citing United States v. Diebold, Inc., 369 U.S. 654, 82 S.Ct. 993, 8 L.Ed.2d 176 (1962)).

Questions of law, on the other hand, are subject to de novo review. N etto v. Amtrak, 863 F.2d 1210,

1212 (5th Cir.1989).

In our review of a district court's decision to grant a motion for summary judgment, we will

affirm that decision if, after examining the entire record, we are convinced that the standard set forth

in Federal Rule of Civil Procedure 56(c) has been met. S ee id. Where, as here, the movant for

summary judgment advanced several independent arguments in district court in support of its motion

for summary judgment, we will affirm if any of those grounds support the district court's decision.

Thus, in our review of the district court's grant of summary judgment in favor of Occidental, we are

not bound to the grounds articulated by the district court; instead, we may affirm the district court's

judgment on other appropriate grounds. S ee Coral Petroleum, Inc. v. Banque Paribas–London, 797

F.2d 1351, 1355 n. 3 (5th Cir.1986) (citing Davis v. Liberty Mut. Ins. Co., 525 F.2d 1204, 1207 (5th

Cir.1976)).

III. EFFECT OF THE STANDSTILL AGREEMENT

One of the g ro unds relied on by the district court in granting summary judgment is the

language of the Standstill Agreement ("SSA"). The district court held that the unambiguous language

of the SSA prohibits Wausau's cross-claim against Occidental. Wausau argues that the district court

er red in it s interpretation of the SSA. In particular, Wausau argues that (a) the SSA permits the7 The SSA defines "Pre-delivery Acts" as those acts concerning (a) the design and construction

of the vessels, (b) the review and approval of technical information, (c) the review and approval of

working plans and drawings, (d) the review and inspection of construction of the vessels and their

components, and (e) the preparation of the vessels for operation. cross-claim as a matter of law, or (b) because the language of the SSA is ambiguous, there is a fact

issue about whether the parties intended to allow such a cross-claim. For the following reasons, we

agree with Wausau's latter argument and accordingly hold that the di stri ct court erred i n granti ng

summary judgment on the basis of language in the SSA.

A. Relevant Provisions of the SSA

The SSA, which was executed prior to the first lawsuit, was a three-party agreement between

the American Underwriters (who were represented by Wausau), Occidental, and Hvide. The purpose

of the agreement, according to the district court, was to allow the parties "to present a united front

in the recovery effort against the various defendants in the consolidated actions." Less than a model

of clarity, the SSA provides, in paragraphs one through four:

1. This Agreement shall not apply to any cause of ac t io n currently being asserted by the

[American] Underwriters, London Underwriters and/or [Occidental] against HVIDE in the

consolidated actions referred to above regarding Pre-delivery Acts [ 7 ] as presently stated and

as the same may be amended; provided, that, such amendments are not inconsistent with this

Agreement.

2. For purposes of the Agreement, a "Subsequent Proceeding" is defined as any mechanism

or process for the resolution of claims or disputes which is commenced after the consolidated

actions have been finally determined, including appeals thereof. [Wausau], [Occidental] and

HVIDE agree not to be bo und in any Subsequent Proceeding by any finding of fact or

decision of law in the consolidated actions which wo uld o therwise be binding upon them

under the principles of res judicata

, collateral estoppel, law of the case or other legal or equitable doctrine with respect to any claims which may be asserted pursuant to paragraph

4 below nor shall such findings of fact or decision of law be admissible for any purpose in any Subsequent Proceeding.

3. The recovery of OXY and the [American] Underwriters and London Underwriters against

the defendants in the OXY PRODUCER Action shall be limit ed to the amounts that may be

adjudged recoverable from any or all defendants reduced by any amount HVIDE may

be

adjudged liable to any co-defendant or plaintiff, by way of contribution or otherwise (a net

recovery) arising from any act or failure to ac t other than a Pre–Delivery Act. In

consideration thereof, HVIDE agrees to discontin ue without prejudice all the HVIDE

Counterclaims; [Occidental] and [Wausau] agree not to assert any additional causes of action

in the consolidated actions against HVIDE with respect to the operati on of the Vessels; and

[Wausau] and [Occidental] agree not to assert any cause of action, except as permitted by

paragraph 4 below, against each other with respect to the subject matter of the consolidated

actions.4. I n t he event that the United States Court in the OXY PRODUCER Action finally

determines, including appeals, that there was a want of due diligence of HVIDE as manager

of the vessel OXY PRODUCER/OXY 4102 under the so-called Liner Negligence clause of

the aforementioned policies and that the recovery of the [American] Underwriters is reduced

by an amount exceeding 20% of the amounts covered and paid under said Hull and Machinery

and Increased Value policies on account of said want of due diligence ("Failure of Due

Diligence Holding"), then [Wausau] may, on behalf of said [American] Underwriters, seek

the recovery in a Subsequent Proceeding of any amounts not recovered on account of said

want of due dili g ence. If no such Failure of Due Diligence Holding is finally made by the

Court then no Subsequent Proceeding shall be instituted or permitted by the United States

Underwriters. Each party hereto agrees, subject to paragraph 2 above and to this paragraph

4, that in any Subsequent Proceeding all substantive or procedural rights, remedies, claims

or defenses they may have as of the date hereof may be asserted, except that each agrees that

any defense of any applicable statute of limitations will be tolled with respect to such rights,

remedies, claims or defenses and each agrees to hereby waive any defense of laches or other

legal or equitable defense based on the lapse of time.

Except as may be limit

ed hereby, it is the intent that the parties hereto shall be left free

to pursue in a

Subsequent Proceeding wheatever [sic] rights they may have as of the date

hereof.

B. Parties' Interpretations of the SSA

Not surprisingly, Occidental and Wausau off er different interpretations of the SSA.

Occidental, citing the last sentence in paragraph three and the first two sentences in paragraph four,

interprets the SSA as a broad waiver of the underwriters' prior reservation of rights. Wausau, on the

other hand, focusing on the entire SSA, reads the agreement as a "broad reservation of rights which

expressly permits the American Underwriters to assert all policy defenses, including breach of the

implied warranty of seaworthiness at the inception of the risk." Occidental and Wausau disagree

specifically about the meaning of paragraphs three and four of the SSA.

1. Occidental's "Broad Waiver" Interpretation

Occidental argues that, under the unambiguous language of the SSA, every "cause of action

not specifically reserved therein" was effectively waived. Occidental then points to the fact that

Wausau and the American Underwriters did not specifically reserve their right to bring a cross-claim

against Occidental for breach of the implied warranty of seaworthiness at the inception of the policy.

Occidental therefore reasons that they waived that right by executing the SSA.

In support of its interpretation that the SSA constituted a broad waiver of claims no t

specifically reserved in the agreement, Occidental primarily relies on language in paragraphs three and

four. The significant language in paragraph three, in Occidental's view, is the last clause, which reads:"[Waus au] and [Occidental] agree not to assert a ny cause of action, except as permitted by

paragraph 4 below, against each other with respect to the subject matter of the consolidated actions."

Occidental argues that this language clearly indicates that paragraph four is an exception to a broad

waiver of claims by Wausau and the American Underwriters. The crucial language in paragraph four,

Occidental contends, is contained in the first t wo sent ences. The first sentence of paragraph four

specifically allows Wausau and the American Underwriters to bring a claim against Occidental if there

is a "Failure of Due Diligence Holding"—i.e., if (i) Hvide is found negl igent in managing the Oxy

Producer ITB and (ii) because of Hvide's post-delivery negligence, the American Underwriters could

not recover at least 80% of the money they had paid in settlement of the claim. The second sentence

of paragraph four states that "[i]f no such Failure o f Due Diligence Holding is finally made by the

Co urt then no Subsequent Proceeding shall be instituted or permitted by the [American]

Underwriters." These two sentences in paragraph four, according to Occidental, evince a waiver of

any right held by Wausau and th e o t her American Underwriters to bring a claim for breach of the

implied warranty of seaworthiness.

Occidental also relies on paragraph one of the SSA to support its waiver interpretation. In

that paragraph, Occidental argues, Wausau and the American Underwriters specifically reserved the

r ight to proceed against Hvide for pre-delivery acts. Because Wausau and the American

Underwriter s did no t make a similar reservation with regard to their right to proceed against

Occidental for pre -delivery acts, the argument goes, the SSA demonstrates that Wausau and the

American Underwriters intended to waive that right.

2. Wausau's "Broad Reservation" Interpretation

Wausau interprets the SSA as an agreement in which it and the other American Underwriters

made a broad reservation of rights. Paragraphs three and four, Wausau argues, do not constitute a

broad waiver of rights, but a narrow exception to the American Underwriters' broad reservation of

right s. Wausau further contends that, because the narrow waiver in those paragraphs was not

triggered by a "Failure of Due Diligence Holding," those paragraphs have no bearing on the right of

the American Underwriters to bring this cross-claim. In short, Wausau views the SSA as expresslypermitting the cross-claim against Occidental.

Wausau first relies on the language of the SSA to support its "broad reservation"

interpretation of the SSA. Wausau points specifically to the last two sentences in paragraph four of

the agreement. The penultimate sentence in paragraph four reads as follows:

Each party hereto agrees, subject to paragraph 2 above and to this paragraph 4, that in any

Subsequent Proceeding all substantive or procedural rights, remedies, claims or defenses they

may have as of the date hereof may be asserted, except that each agrees that any defense of

any applicable statute of limitations will be tolled with respect to such rights, remedies, claims

or defenses and each agrees to hereby waive any defense of laches or other legal or equitable

defense based upon the lapse of time.

Wausau argues that if Occidental's interpretation prevails, the sentence just quoted is rendered

meaningless. In it s brief, Wausau emphasizes that "[i]f the only substantive basis [the] American

Underwriters had to recover the policy proceeds was Hvide's manage rial negligence, this savings

provision would be absolutely unnecessary." Wausau also points to the last sentence of paragraph

four, which provides: "Except as may be limit ed hereby, it is the intent that the parties hereto shall

be left free to pursue in a Subsequent Proceeding wheatever [sic] rights they may have as of the date

hereof." The first clause of the sentence, Wausau argues, demonstrates that the parties intended the

limit at io n in paragraph four—the same limitation relied on by Occidental to demonstrate a bro ad

waiver of rights—to be an exception to a broad reservation of rights b y Wausau and the other

American Underwriters.

Wausau also relies on the SSA's broader purpose, which was to maintain a united front among

the plaint iffs in the recovery actio n against Avondale, Henry, Victoria, and Hvide, to support its

interpretation of the SSA. According to Wausau, "The united front was created and maintained by

requiring the American Underwriters to "stand st ill' in the prosecution of policy defenses that would

blunt or undermine the recovery action." Wausau further maintains that "it is inconceivable that an

agreement that became known by all parties as "the Standstill Agreement,' could, in fact, be a waiver

of all policy defenses by the American Un derwrit ers." Thus, under Wausau's reading of the SSA,

because there is no express waiver of the American Underwriters' right to bring this cross-claim, the

SSA permits the action as a matter of law.

C. Appropriateness of the District Court's Interpretation of the SSA8 We note that the district court technically may have applied the wrong law to this contract

interpretation question. The case relied on by the district court in its discussion of the

SSA— Freeman v. Continental Gin Co., 381 F.2d 459 (5th Cir.1967)—is a diversity case in

which Mississippi contract principles governed. The state of Mississippi has no connection to the

contract at issue here—a contract which (1) was executed in Louisiana, (2) related to litigation

that was pending in federal district court in Louisiana, and (3) is now being construed to bar an

insurer's right to recover proceeds paid under a marine insurance policy issued in Florida.

In addition, there is some question as to whether state or federal law should

govern the interpretation of the SSA. If the SSA does not implicate maritime concerns,

then state law would govern the interpretation question. See Erie R. Co. v. Tompkins,

304 U.S. 64, 78, 58 S.Ct. 817, 822, 82 L.Ed. 1188 (1938); Klaxon Co. v. Stentor Elec.

Mfg. Co., 313 U.S. 487, 496, 61 S.Ct. 1020, 1021, 85 L.Ed. 1477 (1941). If the SSA is

considered a maritime contract, however, its construction would "normally [be] governed

by federal rather than state law." M.O.N.T. Boat Rental Servs. v. Union Oil Co. of Cal.,

613 F.2d 576, 579 n. 6 (5th Cir.1980) (citing Halliburton Co. v. Norton Drilling Co., 302

F.2d 431 (5th Cir.1962), cert. denied, 374 U.S. 829, 83 S.Ct. 1870, 10 L.Ed.2d 1052

(1963); see also Kenney v. Trinidad Corp., 349 F.2d 832, 834 (5th Cir.1965) ("It is clear

that in an admiralty case the Court is not bound by Erie and Klaxon "), cert. denied, 382

U.S. 1030, 86 S.Ct. 652, 15 L.Ed.2d 542 (1966). But cf. Wilburn Boat Co. v. Fireman's

Fund Ins. Co., 348 U.S. 310, 321, 75 S.Ct. 368, 374, 99 L.Ed. 337 (1955) (recognizing

that, although marine insurance contracts are maritime in nature, courts construing such

contracts should look to state law where there is no well-established federal rule on the

particular point in question).

We need not resolve this choice of law issue on appeal, however, because it has

been virtually ignored by the parties. In the district court, Occidental cited numerous

federal cases applying state contract principles to argue for its interpretation of the SSA.

See, e.g., Tokio Marine & Fire Ins. Co. v. McDonnell Douglas Corp., 617 F.2d 936, 940

(2d Cir.1980) (applying California law); How ard v. Russell Stover Candies, Inc., 649

F.2d 620, 623 (8th Cir.1981) (applying Missouri law). Wausau, in its reply to Occidental's

motion for summary judgment, cited 18 C OUCH ON I NSURANCE 2d § 71:46, to support i ts interpretation of the SSA. On appeal, Wausau now notes in its brief that "[t]here was

some dispute below as to what law should apply," but argues that either New York or

Florida law should govern the interpretation of the SSA. Occidental, conversely, cites no

law in its briefing on the meaning and effect of the SSA.

We stated in Kucel v. Walter E. Heller & Co., 813 F.2d 67, 74 (5th Cir.1987), that

a party has "an obligation to call the applicability of another [forum's] law to the court's

attention in time to be properly considered." But see Empire Life Ins. Co. of Am. v.

Valdak Corp., 468 F.2d 330, 334 (5th Cir.1972) (raising, sua sponte, the district court's

erroneous decision to apply the Uniform Commercial Code before its effective date). In

American Int'l Trading Corp. v. Petroleos Mexicanos, 835 F.2d 536 (5th Cir.1987),

however, we recognized our power to address a choice of law issue for the first time on

appeal where manifest injustice would result. See id. at 540 (parties are bound by the

theory of law they argue in district court absent manifest injustice). Because the choice of

law issue was not raised below, and because we find no manifest injustice in refusing to

decide the issue on appeal, we decline to address it. The district court, relying on our decision in Freeman v. Continental Gin Co., 381 F.2d 459

(5th Cir.1967), 8 adopted the interpretation of the SSA advanced by Occi dent al and held that thelanguage of that agreement bars Wausau's cross-c laim as a matter of law. The district court first

found the language in the SSA to be "clear and unambiguous." The district court further found that

Wausau and the American Underwriters waived their "right to bring this cross[-]claim unless there

was a finding by the court in the liability action that there was a lack of due diligence on the part of

HVIDE, as manager of the vessel." Because no such lack of due diligence finding was ever made,

the district court reasoned, the cross-claim is barred.

The district court's grant of summary judgment on this ground is premised on the conclusion

that the language of

t he SSA is unambiguous. A conclusion that a contract is ambiguous—as the

district court recognized—is a question of law. Thus, we review the district court's determination

de novo. First Nat'l Bank of Jackson v. Pursue Energy Corp., 799 F.2d 149, 151 (5th Cir.1986).

In our view, th e SSA is not clear and unambiguous. First, it is unclear what the parties

intended by the last clause of paragraph three, which states that Wausau and Occidental "agree not

to assert an y cause of action, except as permitted by paragraph 4 below, against each other w ith

respect to the subject matter of the consolidated actions. " (emphasis added). Because the SSA does

not define what is meant by "the subject matter of the consolidated actions," we cannot determine

whether Wausau and the American Underwriters' cross-claim against Occidental is included within

the terms of that clause. Furthermore, although the provisions relied on by Occidental and the district

court in paragraph four—when read out of context—appear clear and unambiguous, those provisions

are unclear and ambiguous when read in the context of the entire paragraph. If Wausau and the

American Underwriters were absolutely precluded from bringing any subsequent ac tion agai nst

Occidental absent a finding that Hvide was negligent in its capacity as manager of the vessel, it would

have been unnecessary to include the last two sentences of paragraph four. We think that the last two

sentences in paragraph four, which speak in terms of a broad reservation of rights, render the meaning

of the first two sentences in the paragraph ambiguous.

In sum, we are unable to determine from the language of the SSA what the parties intended

repres ent a bro ad waiver of rights with a narrow reservation—is a reasonable one. However, the9 Our decision in D.J. McDuffie, Inc. v. Old Reliable Fire Ins. Co., 608 F.2d 145, 147 n. 1 (5th

policies. But see also Russell W. Pritchett, The Implied Warranty of Seaw orthiness in Time

"it is arguable that state law should control"). interpretation advanced by Wausau—that the paragraphs represent a broad reservation of rights with

a narrow waiver— is also reasonable. There is a fact issue concerning the parties' intent.

Accordingly, the district court erred in granting summary judgment in favor of Occidental on the basis

of the SSA.

IV. IMPLIED WARRANTY OF SEAWORTHINESS AT THE INCEPTION OF A TIME

POLICY

On appeal—as an independent ba sis fo r affirming the district court's summary

judgment—Occidental contends that, under the undisputed facts, it did not breach any warranty of

seaworthiness implied at the inception of a time hull policy. Occidental argues specifically that "the

only implied warranty relating to seaworthiness under a time hull policy, is that the insured will not

knowingly send the vessel to sea in an unseaworthy condition." Because there was no finding in the

first litigation that it knowingly se nt t he vessel to sea in an unseaworthy condition, Occidental

reasons, Wausau's cross-claim is barred.

The district court did not expressly grant summary judgment for Occidental on this ground,

but it did conclude "that a breach of the warranty of seaworthiness at the inception of an insurance

policy will void the policy only if the shipowner has prior knowledge of the unseaworthy condition."

In reaching this conclusion, the district court recognized that several decisions of this court purported

to embrace an absolute warranty of seaworthiness in a time hull policy at the moment of attachment.

The district court nonetheless reasoned that such cases were inapplicable.

We think that the district court misperceives our prior decisions. As discussed below, federal

marit ime law 9 implies two warranties of seaworthiness in a time hull insurance policy. The first of

these warranties—the implied warranty of seaworthiness at the inception of the policy—is absolute

in nature. The second one, which applies only after the policy attaches, is a mo dified, negative10 Voyage policies insure a vessel for a single voyage, whatever the duration. Time policies, by

contrast, insure a vessel for an unspecified number of voyages during a specified duration. Derek

Standard in Time Hull Insurance Policies, 39 M E .L.R EV . 443, 449 (1987) (citation omitted). warranty, under which the insured promises not to knowingly send a vessel to sea in an unseaworthy

condition. Although the second implied warranty of seaworthiness requires knowledge on the part

of the insured, the first do es not. The insured breaches this first warranty if the vessel is i n fact

unseaworthy when the policy becomes effective. Accordingly, Occidental is not entitled to summary

judgment on the ground that, because it had no knowledge of the vessel's unseaworthiness, it did not

breach the warranty of seaworthiness implied at the inception of the time hull policy.

A. Evolution of the Implied Warranties of Seaworthiness in Time Hull Policies

The implied warranties of seaworthiness in time hull policies are unique to American marit ime

law. S ee generally Russell W. Pritchett, The Implied Warranty of Seaw orthiness in Time Policies:

The American View, 1983 L LOYD ' S M AR

. & C OM .L. 195. Accordi ng to one com m entator, "[t]he

present American rule for implied warranties in time policies is a h ybrid of the English rules for

voyage and time policies." Derek P. Langhauser, Note, I mplied Warranties of Seaw orthiness:

Applying the Know ing Neglect Standard in Time Hull Insurance Policies, 39 M E .L.R EV

. 443, 449

(1987). Thus, before describing the two warranties of seaworthiness implied in time hull policies

under the American rule, we examine the sources of those warranties.

1. Implied Warranty of Seaw orthiness in Voyage Policies

It is well-settled under marit ime law in England and America that there is an implied warranty

of seaworthiness in "voyage" insurance policies. 10 In The Caledonia, 157 U.S. 124, 131, 15 S.Ct.

537, 540, 39 L.Ed. 644 (1895), the Supreme Court stated:

Every person who proposes to any insurers to insure his ship against sea perils, during a

certain voyage, impliedly warrants that his ship is, in every respect, in a suitable condition to proceed and continue on that voyage, and to encounter all common perils and dangers with

safety. * * * This warranty is strictly a condition precedent to the obligation of insurance;

if it be no t performed, the policy does not attach; and, if this condition be broken, at the

inception of the risk, in any way whatever and from any cause whatever, there is no contract of insurance, the policy being wholly void.

Id. at 131, 15 S.Ct. at 140 (quoting P ARSONS

, 91 M AR

. I NS

. 367). Similarly in England, sect io n39(1) of the Marine Insurance Act of 1906 provides: "In a voyage policy there is an implied warranty

that at the commencement of the voyage the ship shall be seaworthy for the purpose of the particular

adventure insured."

The implied warranty of seaworthiness in a voyage policy is absolute in nature. S ee 1 A LEX

L. P ARKS

, T HE L AW AND P RACTICE OF M ARINE I NSURANCE AND A VERAGE 258 (1987) ("The cases

are legion establishing that in a voyage policy, the law implies a warranty on the part of the assured

which amounts to a positive undertaking—an absolute conditio n—that the vessel at the

commencement of the voyage is seaw o rthy"). The word "warranty" in this context, according to

Professors G ilmo re and Black, "has its most drastic meaning." G R ANT G ILMORE & C HARLES L.

B LACK

, T HE L AW OF A DMIRALTY § 2–6, at 63 ( 2d ed. 1975). If the implied warranty of

seaworthiness in a voyage policy is breached—that is, if "the vessel is not in fact seaworthy at the

beginning of the voyage or at the inception of the risk—then no recovery can be had on the policy.

This result does not depend on the knowledge or faul t of the assured." I d. (citing Richelieu &

Ontario Nav. Co. v. Boston Marine Ins. Co., 136 U.S. 408, 429, 10 S.Ct. 934, 940, 34 L.Ed. 398

(1890), and Bullard v. Roger Williams Ins. Co., 1 Curt. 148, 4 Fed.Cas. 643 (C.C.D.R.I.1852) (No.

2122)). Nor does this result depend on the subsequent loss being directly attributable to the lack of

seaworthiness. S ee Gregoire v. Underw riters at Lloyds, 559 F.Supp. 596, 598 (D.Alaska 1982)

(citing G ILMORE & B LACK

, supra, at § 2–6).

The absolute nature of this implied warranty of seaworthiness is grounded in a public policy

choice. The warrant y is intended to take "away all temptation to expose life and property to the

dangers of the seas in vessels not fitted to encounter or avoid them." T he Caledonia, 157 U.S. at

134, 15 S.Ct. at 541 (quoting the jury charge given in Bullard v. Insurance Co. ). It is premised on

the noti o n t hat, because the insured is best able to foresee the nature, extent, and necessities of a

specific voyage, the insured is also best able to have the vessel adequately prepared for that voyage.

See Langhauser, supra, at 449 (citing Hoxie v. Pacific Mut. Ins. Co., 89 Mass. (7 Allen) 211, 225

(1863), and Capen v. Washington In s. Co., 66 Mass. (12 Cush.) 517, 536 (1853)). In short, the

absolute warranty implied in every voyage insurance policies represents an early attempt by the lawto place the risk of loss on the cheapest cost avoider. S ee also G ILMORE & B LACK

wholesome effect on the discipline o f the shipping industry in early, less well-policed days"); c f.

, T HE C OSTS OF A CCIDENTS (1970).

2. Implied Warranty of Seaw orthiness in Time Policies—English Rule

Under English law, there is no implied warranty of seaworthiness in a time policy; however,

the insurer can escape liabilit y in certain limit

ed circumstances. Section 39(5) of the Marine Insurance

Act of 1906 provides:

In a time policy there is no implied warranty that the ship shall be seaworthy at any stage of

the adventure, but where, with the privity of the as sured, the ship i s sent to sea i n an unseaworthy state, the insurer is not liable for any loss attributable to unseaworthiness.

The English rule regarding time policies can thus be separated into two parts. Under the first part

of the rule, there is no absolute warranty t hat t racks the warranty of seaworthiness in voyage

insurance policies. A vessel's condition of unseaworthiness cannot void a time insurance po licy.

Under the second part of the English rule, however, an insurer may be able to disclaim liabilit y for

a particular loss if it can demonstrate that (1) the vessel was unseaworthy, (2) the insured was privy

to vessel's condition when it was sent to sea, and (3) the unseaworthy condition proximately caused

the particular loss. See W ILLIAM G OW

, M ARINE I NSURANCE 272 (4th ed. 1909).

The rationale behind the English rule regarding time policies, as embodied in section 39(5)

of the Marine Insurance Act of 1906, is somewhat unclear. One commentator views the act as merely

declaring the common law and expressing "the gist of a great many decisions." 1 P ARKS

, supra, at

264. Ot hers view the English rule as somehow representing equitable considerations. S ee G OW

,

supra, at 272 (reasoning that, because a time policy could commence when a vessel is at sea—beyond

the knowledge and control of her owner—"insistence on the warranty in such a case might become

inequitable"); s ee also Pritchett, supra, at 197 (tracing English refusal to imply wa rranty of

seaworthiness in time policies to Gibson v. Small, 4 H.L.Cas . 352 (1853), a case in which the

shipowner obtained a time policy while the vessel was on a voyage). Finally, still another

commentator considers section 39(5) of the Marine Insurance Act of 1906 to represent a legislative11 See, e.g., Lloyd's U.S. Corp. Smallw ood, 719 F.Supp. 1540, 1549 (M.D.Fla.1989), aff'd, 903

F.2d 828 (11th Cir.1990). compromise between the arguments advanced by shipowners against implying an absolute warranty

in time policies and the arguments advanced by insurers in favor of such a warranty. S ee Langhauser,

supra, at 449–50.

3. Implied Warranties of Seaw orthiness in Time Policies—American Rule

The American rul e regarding the implied warranties of seaworthiness in time insurance

policies is set forth in our decision in Saskatchew an Government Insurance Office v. Spot Pack, Inc.,

242 F.2d 385 (5th Cir.1957). After describing the English rule regarding t he implied warranty of

seaworthiness in time hull policies, we stated:

But the American Rule, in a rare departure from a determined course of parallel uniformity,

... implies for a time policy, as does the English Rule as of the commencement of the voyage for voyage policies, ... a warranty of seaworthiness as of the very moment of attachment of

the insurance. And unlike the English Rule which limits the warranty to the commencement

of the voyage, the American Rule takes it somewhat further to extend, in point of time, a sort

of negative, modified warranty. It is not that the vessel shall continue absolutely to be kept

in a seaworthy condition, or even that she be so at the inception of each voyage, or before

departure from each port during the policy term. It is, rather, stated in the negative that the

Owner, from bad faith or neglect, will not knowingly permit the vessel to break ground in an unseaworthy condition. And, unlike a breach of a warranty of continuing seaworthiness,

express or implied, which voids the policy altogether, the consequence of a violation of this

"negative' burden is merely a denial of liabilit y for loss or damage caused proximately by such

unseaworthiness.

Id. at 388 (citations omitted). In this passage, Judge Brown recognized two implied warranties of

seaworthiness in a time policy. The first one—"a warranty of seaworthiness as of the very moment

of attachment of the insurance"—is akin to the absolute warranty of seaworthiness implied in voyage

policies under the English Rule. The second one, which has been labelled a modified, negative

warranty, 11 looks very much like the second part of the English rule regarding the implied warranty

of seaworthiness in a time policy. That is, under the second warranty, the insured does not absolutely

warrant that the vessel shall continue to be seaworthy for the duration of the policy, but only that he

or she, "from ba d fait h or neglect, will not knowingly permit the vessel to break ground in an

unseaworthy condition."

Although we described the American rule in Spot Pack as being settled, we recognized that12 Several courts, Occidental argues, have rejected our description of the American rule in Spot

Pack. In New

York, New

Haven and Hartford R. Co. v. Gray, 240 F.2d 460, 466 n. 10 (2d Cir.),

cert. denied, 353 U.S. 966, 77 S.Ct. 1050, 1 L.Ed.2d 915 (1957), the Second Circuit noted that "[h]ow this came to be the rule of general acceptance for all Time policies is obscure." 242 F.2d at

388. Commentators were also perplexed by the source of the so-called American rule regarding time

policies, and our decision in Spot P ack was crit icized as resting on "quite slender" authority. S ee

G ILMORE & B LACK

, supra, § 2–6, at 63; see also Pritchett, supra, at 196 ("the "American Rule' is

not so well established as its name implies"). More recently, a federal district court in Alaska opined

that "the great majority of the decided cases in this country are consistent with the English Rule," and

accordingly rejected the Spot Pack formulation of the American rule. Gregoire v. Underw riters at

Lloyds, 559 F.Supp. at 600–01.

We are aware of the criticism that has been levelled against our Spot Pack decision; however,

we decline to revise our interpretation of history. Since our decision in S pot Pack we have on several

occasions reaffirmed our description of the American ru le regarding the implied warranties of

seaworthiness in time policies. See, e.g., Insurance Co. of North Am. v. Board of Comm'rs. of the

Port of New Orleans, 733 F.2d 1161, 1165 (5th Cir.1984); D .J. McDuffie, Inc. v. Old Reliable Fire

Ins. Co., 608 F.2d 145, 147 (5th Cir.1979), cert. denied, 449 U.S. 830, 101 S.Ct. 97, 66 L.Ed.2d 35

(1980); Gulfstream Cargo, Ltd. v. Reliance Ins. Co., 409 F.2d 974, 983 (5th Cir.1979); Tropical

Marine Prods., Inc. v. Birmingham Fire Ins. Co . of Pa., 247 F.2d 116, 119 (5th Cir.1957), cert.

denied, 355 U.S. 903, 78 S.Ct. 331, 2 L.Ed.2d 260 (1957). In addition, several other circuits have

adopted the Spot Pack description of the American rule. S ee L & L Marine Serv., Inc. v. Insurance

Co. of North Am., 796 F.2d 1032, 1035 (8th Cir.1986), cert. denied, 479 U.S. 1065, 107 S.Ct. 952,

93 L.Ed.2d 1000 (1987); K ilpatrick Marine Piling v. Fireman's Fund Ins. Co., 795 F.2d 940, 945

(11th Cir.1986); s ee also McAllister Lighterage Line, Inc. v. Insurance Co. of North Am., 244 F.2d

867, 870 (2d Cir.1957) (recognizing, under Supreme Court's decision in U nion Ins. Co. of

Philadelphia v. Smith, 124 U.S. 405, 8 S.Ct. 534, 31 L.Ed. 497 (1888), that in a t erm policy of

insurance a warranty of seaworthiness arises at the time when the insurance becomes effective), cert.

denied, 355 U.S. 872, 78 S.Ct. 123, 2 L.Ed.2d 77 (1957). 12 Finally, we remain convinced that thethere were statements in American cases to the effect that time policies carry with them an implied

warranty of seaworthiness. The Second Circuit in Gray nonetheless opined that the language in

those cases was dicta. However, shortly after Gray was decided, the Second Circuit, in

McAllister Lighterage Line, embraced the concept of an implied warranty of seaworthiness

arising at the inception of a time insurance policy.

13 In most of the cases discussing the implied warranties of seaworthiness in a time hull policy,

it was the negative, modified warranty of seaworthiness that was at issue. See, e.g., L & L

Marine Serv., Inc. v. Insurance Co. of North Am., 796 F.2d 1032, 1035 (8th Cir.1986), cert.

denied, 479 U.S. 1065, 107 S.Ct. 952, 93 L.Ed.2d 1000 (1987); Insurance Co. of North Am. v.

Board of Comm'rs of the Port of New Orleans, 733 F.2d 1161, 1165 (5th Cir.1984); Tropical

Marine Prods., Inc. v. Birmingham Fire Ins. Co. of Pa., 247 F.2d 116, 119 (5th Cir.), cert.

denied, 355 U.S. 903, 78 S.Ct. 331, 2 L.Ed.2d 260 (1957); Saskatchew an Govt. Ins. Office v.

Spot Pack, 242 F.2d 385, 387 (5th Cir.1957); Lloyd's U.S. Corp. v. Smallw ood, 719 F.Supp. general principles described in Spot Pack are sufficiently grounded in precedent. S ee Pritchett, supra,

at 198–208.

B. Nature of the Implied Warranty of Seaworthiness at the Inception of a Time Policy Under the

American Rule

This c ase concerns the precise contours of the first warranty described in our S pot Pack

decision. There are at least three unresolved questions about the contours of this warranty. First,

does the existence of

an implied warranty of seaworthiness at the inception of a time hull policy

depend on whether the vessel is at port or at sea when the policy attaches? Second, do principles of

causation have any role in determining whether a condition of unseaworthiness at the inception of a

time policy precludes recovery under the policy? And third, is the implied warranty of seaworthiness

at the inception of a time hull policy absolute in nature—such that it is breached if the vessel is in fact

unseaworthy at the time the policy attaches?

We need only resolve the last question in this case, because the first two questions are not

raised. It is undisputed that, when the policy at issue became effective, the Oxy Producer ITB was

at a port of repair and not at sea. Moreover, the first lawsuit established that the unseaworthy

condition of OXY Producer ITB at the time the policy attached was the sole cause of the loss of the

Oxy Producer. Thus, we need only decide whether a breach of the implied warranty of seaworthiness

at the inception of a time hull policy requires knowledge or fault on the part of the insured.

We first look to the few cases in which the implied warranty of seaworthiness at the inception

of a time policy was at issue. 13 In Gulfstream Cargo, Ltd. v. Reliance Insurance Co., we held that1540, 1549 (M.D.Fla.1989), aff'd, 903 F.2d 828 (11th Cir.1990); Gregoire v. Underw riters at

Lloyds, 559 F.Supp. 596, 599 (D.Alaska 1982); Lemar Tow ing, Inc. v. Fireman's Fund Ins. Co.,

352 F.Supp. 652, 660 (E.D.La.1972), aff'd, 471 F.2d 609 (5th Cir.1973), cert. denied, 404 U.S.

976, 94 S.Ct. 292, 38 L.Ed.2d 219 (1973). the existing, "spectacular" unseaworthiness of the vessel—at the moment the time poli cy was to

at tach—kept the policy from becoming effective. 409 F.2d at 983. As Occidental points out,

however, this holding does not aid our inquiry, because in Gulfstream the insured was charged with

k nowledge of the vessel's unseaworthy condition. S ee id. at 976. Si m i l ar facts surrounded the

condition of unseaworthiness in D.J. McDuffie, Inc. v. Old Reliable Fire Insurance Co., a case in

which we affirmed the district court's finding that the insured had breached its implied warranty of

seaworthiness at the inception of the time policy. 608 F.2d at 147. In M cDuffie, as in Gulfstream,

there was evidence that the insured had knowledge of the unseaworthy condition at the inception of

the policy. S ee McDuffie, 608 F.2d at 147 ("The [insured's] expert witness testified that one month

before the policy was to take effect, he had recommended that [the vessel] be drydocked for critical

repairs."); s ee also McAllister Lighterage Line v. Insurance Co. of North Am., 244 F.2d at 870–71

(holding that unseaworthiness of vessel brea ched an express as well as the implied warranty of

seaworthiness at the inception of time policy). We conclude, therefore, that the cases addressing this

warranty do not decide the issue of whether knowledge of the vessel's unseaworthiness or fault on

the part of the insured is a prerequisite for finding a breach.

We thus turn to our decision in Spot Pack for guidance. There we equated the warranty of

seaworthiness implied at the inception of a time hull policy with the warranty of seaworthiness implied

in a voyage policy. See 242 F.2d at 388. This latter warranty, according to well-settled precedent,

is absolute in nature. As stated in Douglas v. Scougall, 4 Dow. 269, 270:

[T]here is nothing in matters of insurance of more importance than the implied warranty that

a ship is seaworthy when she sails on the voyage insured.... It is not necessary to inquire

whether the owners acted honestly and fairly in the tran sact io n; for it is clear law that,

however just and honest the intentions and conduct of the owner may be, if he is mistaken

in fact, and the vessel is in fact not seaworthy, the underwriter is not liable.

(emphasis added), quoted in The Caledonia, 157 U.S. 124, 133–34, 15 S.Ct. 537, 541, 39 L.Ed. 644

(1895). Accordingly, by tracing t he implied warranty of seaworthiness at the inception of a time14 We note that it is the insurer who has the burden of demonstrating that the vessel was

unseaworthy at the moment the time policy attached. See Spot Pack, 242 F.2d at 389. This

burden is not insubstantial. insurance policy to its root—the implied warranty in voyage policies—we conclude that the warranty

is absolute in nature, requiring neither knowledge nor fault on the part of the insured.

The sound reasons supporting an absolute, implied warranty of seaworthiness at the inception

of a voyage policy also support such a warranty in the context of a time policy—at least where the

ship is in a port of repair at the time the policy attaches. It is the insured, not the insurer, who is best

able to foresee the intended use of the vessel during the term of a time policy. Consequently, it is the

insured, not the insurer, who is in the best position to see that the vessel is adequately prepared for

its intended use. Where, as in this case, a time policy attaches while the vessel is in a port of repair,

we can discern no reason for relaxing the strict standard embodied in the absolute warranty of

seaworthiness implied in a voyage policy. To require knowledge or fault on the part of the insured,

in addition to a finding that the ve ssel was unseaworthy at the inception of the policy, 1 4 we think,

would di sco urage the owners of vessels from taking steps to assure that the vessel is adequately

prepared for its intended use.

In sum, we hold that the warranty of seaworthi ness implied at the inception of a time hull

policy is absolute in nature. The insurer need not demonstrate that the insured had knowledge of the

unseaworthy condition nor that the insured was somehow at fault in not discovering the unseaworthy

co ndition. It is enough to discharge the insurer, as noted in S cougall, if "the vessel is in fact not

seaworthy" at the inception of the policy. We need not and do not decide, however, whether (a) the

absolute warranty arises if the vessel is at sea at the inception of the time policy, or (b) an insurer may

claim benefit of the absolute warranty of seaworthiness impli ed at the inception of the risk if the

condition of unseaworthiness does not cause the particular loss.

C. Appropriateness of Summary Judgment on the Basis of Occidental's Compliance with the Implied

Warranty of Seaworthiness at the Inception of a Time Policy

The undisputed facts of the case demonstrate that Occidental was not entitled to summary

judgment on the ground that it complied with the warranty of seaworthiness at the inception of the15 The latest American version of the Inchmaree Clause provides coverage for (a) accidents in

loading, discharging or handling cargo, or in bunkering; (b) accidents in going on or off, or while

on drydocks, graving docks, ways, gridirons or pontoons; (c) explosions on shipboard or

elsewhere; (d) breakdown of motor generators or other electrical machinery and electrical policy. In the first lawsuit, the district court found that the Oxy Producer ITB was improperly mated

and unseaworthy on delivery to Occidental. The district court also found that this unseaworthy

condition was the sole cause of the sinking of the Oxy Producer. Absent some waiver of the implied

warranty of seaworthiness at the inception of the policy, these findings , which were affirmed on

appeal, demonstrate as a matter of law that Occidental did not comply with this absolute warranty.

Summary judgment in favor of Occidental on this ground would be wholly inappropriate.

V. DISPLACEMENT OF THE IMPLIED WARRANTY OF SEAWORTHINESS AT THE

INCEPTION OF A TIME HULL POLICY

Our decision concerning the absolute nature of the implied warranty of seaworthiness at the

inception of a t ime po licy does not resolve this dispute, because the district court held that two

provisions in Occidental's time hull policy effectively waive or displace that warranty. The district

court first concluded that the Liner Negligence Clause of the policy ef fect ively supersedes the

warranty. The district court also ruled that the Separate Policy of Insurance Treatment Clause

("Separate Policy Clause") provides coverage for the loss of the Oxy Producer even though Hvide,

a co-insured, was found partly responsible for the vessel's unseaworthiness. We address each of these

holdings in turn.

A. Effect of Liner Negligence Clause

Almost every time hull

po licy no w contains an "Inchmaree Clause." This clause affords

coverage for certain perils that are not included within the classic "perils" clause. S ee generally 1

purpose of such a clause is to broaden the coverage under a marine insurance policy. Goodman v.

Fireman's Fund Ins. Co., 600 F.2d 1040, 1042 (5th Cir.1979). Today, a typical Inchmaree Clause

hereunder; (h) negligence of masters, officers, crew or pilots, provided such loss or damage has

not resulted from want of due diligence by the assured, the owners or managers of the vessels, or

any of them. Instead of an Inchmaree Clause, the insurance policy issued to Occidental contains a Liner

Negligence Clause. This latter clause, it is recognized, pro vides even broader coverage than the

standard Inchmaree Clause. S ee 1 P ARKS

(emphasis added). According to one commentator, the Liner Negligence Clause "is really a species

of an "all risks' policy," under which the underwriter must "prove that the cause of the loss was one

which was excluded by the words of the policy." 1 P ARKS

, supra, at 404.

The district court concluded that the Liner Negli gence Clause in the policy issued to

Occidental "supplants and is a substitute for any implied warranty of seaworthiness" at the inception

of the policy. The district court focused specifically on the language which indicates that coverage

is provided for loss caused directly by the "negligence, error o f judgment or incompetence of a ny

person; ... provided such loss ... has not resulted from want of due diligence by the Assured(s), the

Owner(s), or Manager(s) of the vessel, or any of them." This provision, the district court reasoned,16 The parties have assumed that federal maritime law governs this question. Therefore, we

assume, without deciding, that federal law controls. See Albany Ins. Co. v. Anh Thi Kieu, 927

F.2d 882, 886–87 (5th Cir.) (describing three-part test used to determine whether, under Wilburn

Boat, state or federal law governs an issue regarding the interpretation of marine insurance), cert.

denied, ––– U.S. ––––, 112 S.Ct. 279, 116 L.Ed.2d 230 (1991). effect ively underwrites the pre-attachment negligence and/or error of judgment by Hvide and

Avondale that rendered the Oxy Producer ITB unseaworthy.

Wausau argues that, because Occidental breached the absolute w arrant y of seaworthiness

implied at the inception of a time policy, the policy is void and the question of coverage under the

Liner Negligence Clause need not be reached. In support of its argument, Wausau cites two cases:

D.J. McDuffie, Inc. v. Old Reliable Fire Insurance Co., 1979 AMC 595 (E.D.La.1977), aff'd, 608

F.2d 145 (5th Cir.1979), cert. denied, 449 U.S. 830, 101 S.Ct. 97, 66 L.Ed.2d 35 (1980), and The

Natalie, 1959 AMC 2379 (arbitratio n). According to Wausau, these two cases demonstrate that,

once the in sured breaches its implied warranty of seaworthiness at the inception of the policy,

recovery is precluded despite the presence of a clause in the policy expanding coverage.

Although Wausau's argument has some logic, it ultimately must be rejected. If we were to

adopt Wausau's reasoning, the insured would effectively be precluded from disclaiming this absolute

implied warranty of seaworthiness in the policy itself. We decline to adopt such a drastic rule.

Moreover, McDuffie and The Natalie are distinguishable from this case because the policies at issue

in those cases contained only Inchmaree Clauses—not Liner Negligence Clauses. At the most, those

ca ses st and only for the proposition that an Inchmaree Clause does not effect an across the board

waiver of the implied warranty of seaworthiness at the inception of a time hull policy.

Thus, in deciding whether the district court erred in construing the Liner Negligence Clause,

we must answer a difficult question: Do es t he Liner Negligence Clause, at least with respect to

pre-attachment negligence or error in judgment by parties involved in the construction of the vessel,

effectively supplant or waive the absolute implied warranty of seaworthiness at the inception of a time

hull policy? This question, although it has received some attention from commentators, has not yet

been squarely addressed by any court. We therefore proceed with caution. 16

Although we have indicated that the implied warranties of seaworthiness in a time hull policymay be disclaimed or waived, we have neve r specified exactly how such a waiver may be

accomplished. Language in I nsurance Co. of North America v. Board of Commissioners of the Port

of New O rleans, 733 F.2d 1161 (5th Cir.1984), suggests that the warranties must be expressly

waived. Id. at 1165 ("A warranty of seaworthiness by the owner is implied in every hull insurance

policy unless expressly waived ") (emphasis added). In Tropical Marine Products, Inc. v.

Birmingh a m Fire Insurance Co. of Pennsylvania, 247 F.2d 116 (5th Cir.), cert. denied, 355 U.S.

903, 78 S.Ct. 331, 2 L.Ed.2d 260 (1957), however, we recognized that an Inchmaree Clause—which

does not expressly m

ent io n any implied warranties of seaworthiness—"affords both an additional

series of perils insured against and mark edly affects the w arranties of seaw orthiness betw een

Shipow ner and Underw riter. " 247 F.2d at 119.

We think that the common sense approach embodied in Tropical Marine is the correct one.

In that case, the insurer argued that the vessel's unseaworthy condition arising after a time policy had

attached voided the policy. We rejected the insurer's argument primarily on the basis of language in

the Inchmaree Clause. The plain language of the clause, we observed, provided coverage for the loss

that had resulted from the vessel's unseaworthy condition. We stated:

Indeed, far from voiding the policy, it was as to just such unseaworthiness that the policy was

meant to apply. An Inchmaree clause insures against damage or loss occasioned by latent

defects in machinery or hull. Of course, a defect in machinery or a defect in a hull means that

t he vessel is thereby unseaworthy since, with such defect, the machinery or hull cannot

comply with the classic definition of "reasonably suitable' for the purposes intended.... The

only limitation on this is that the defect be latent and one not known or discoverable by the

owner or one in privy with him.

247 F.2d at 12 0–21. Therefore, in determining the extent to which a clause in a time hull policy

supersedes or waives an implied warranty of seaworthiness, a court should look to the language of

the provision to see if it unambiguously covers risks which would ordinarily be excluded by a breach

of the implied warranty of seaworthiness. If the clause does cover such a risk, then it may be said that

the clause underwrites that particular type of unseaworthiness. See id. at 123.

A careful r eading of the Liner Negligence Clause in the policy issued to Occidental

demonstrates that it effected at least a partial waiver of the absolute warranty of seaworthiness

implied at the inception of the pol icy. The language of the clause is clear and unambiguous: itprovides coverage for loss caused by the "[n]egligence, error of judgment or incompetence of any

person." (emphasis added). This provision, unlike the negligence provisions in the Inchmaree Clause,

does not limit coverage to operational negligence. Instead, it is worded broadly enough to include

the negligence of shipbuilders and the construction mana ger. See 1 P A RKS

, supra, at 406

(subparagraph (b) of the standard Liner Negligence Clause covers the negligence of a "builder, and

is not limit

ed to masters, crew, engineers, pilots, and re pairers or charterers as in the ordinary

Inchmaree Clause"); L E SLIE J. B UGLASS

, M ARINE I NSURANCE AND G ENERAL A VERA G E IN THE

U NITED S TATES 139 (2d ed. 1981) (n egligence of builders is covered under the Liner Negligence

Clause but not under the Inchmaree Clause).

The only limit to the partial waiver of the implied warranty of seaworthiness at the inception

of the risk under the Liner Negligence Clause is that the loss must not have resulted from a "want of

due dili gence by t he Assured(s), the Owner(s), or Manager(s) of the vessel." Under the Separate

Policy of Insurance Treatment Clause, see infra Part V.B., Occidental is treated as the only "assured"

under the due diligence porti on of the Liner Negligence Clause. Therefore, to come within the

protection of the Liner Negligence Clause, the loss in this case must not have resulted from a want

of due diligence by Occidental, in its role as assured or owner, or from a want of due diligence by

Hvide in its role as manager of the vessel.

In our view, the undisputed facts demonstrate that the loss of the Oxy Pro ducer was not

caused by any lack of due diligence on the part of Occidental in its status as assured/owner, nor by

any lack of due diligence on the part of Hvide as manager of the vessel. In the first lawsuit, it was

determined that the actions of Hvide, as construction supervisor, and Avondale, as the builder of the

vessel, were the sole cause of the loss. S ee Employers Ins. of Wausau v. Suwanee River Spa Lines,

Inc., 866 F.2d at 773. There is no contention by Wausau that Occidental itself was somehow

responsible for the vessel's unseaworthy condition. In addition, contrary to Wausau's argument,

Hvide's want of due diligence as construction supervisor cannot, as a matter of law, be imputed to

Occidental, because Hvide was not an agent of Occidental's, but instead an independent contractor.

Se e id. at 773–74 (concluding that Hvide, in its role as construction supervisor, had no actual orapparent authority to bind Occidental). Finally, we decline to impute Hvide's lack of due diligence

as construction supervisor to Hvide as manager. Therefore, the due diligence portion of the Liner

Negligence Clause does not exclude the type of unseaworthiness at issue here.

In sum, we hold that the district court correctly granted summary judgment i n favor of

Occidental on the basis of the Liner Negligence Clause. The plain language of that clause effectively

underwrites the unseaworthiness that caused the sinking of the Oxy Producer. In essence, it covers

loss caused by the negligence of any person other than the insured, the owner, or the manager of the

vessel. For purposes o f t his case, it is broad enough to cover the negligence of Hvide as the

construction supervisor and the negligence of Avondale as the ship builder. At least to this extent,

then, the Liner Negligence Clause waives or displaces the absolute warranty of seaworthiness implied

at the inception of a time policy.

B. Effect of Separate Policy of Insurance Treatment Clause

The district court also granted summary judgment on the basis of the Separa t e Policy of

Insurance Treatment Clause, under which "all terms, conditions, and exclusions [are] treated as if a

separate policy of insurance were issued to each assured." This clause, the district court reasoned,

prevents the negligence of Hvide in supervising the mating of the ve s sel from being imputed to

Occidental. The district court accordingly concluded that the Separate Policy Clause independently

provides Occidental with coverage for the loss of the Oxy Producer.

We hold that the district court erred in granting summary judgment solely on the basis of the

Separate Policy Clause. This clause, unlike the Liner Negligence Clause, does not displace or waive

the implied warranty of seaworthiness at the inception of the risk. Instead, as Wausau points out, the

Separate Policy Clause "requires each assured to comply with policy requirements "as if a separate

policy of insurance were issued' to that assured individually." Thus, under Occidental's hypothetical

separate time hull policy, it would have been require d—but for the Liner Negligence Clause—to

independently comply with the absolute warranty of seaworthiness implied at the moment the policy

attached. The Separate Policy Clause, while it affected the operation of the Liner Negligence Clause,

by itself neither displaced nor cha nged t he terms of the implied warranty of seaworthiness at theinception of the policy.

VI. WAIVER AND ESTOPPEL

As additional grounds supporting the district court's grant of summary judgment, Occidental

argues that Wausau and the American Underwriters have waived or are estopped to assert this

cross-claim. Occidental argues specifically that, by voluntarily paying the loss after they had adequate

time to investigate the circumstances surrounding the loss, Wausau and the American Underwriters

waived their right to assert policy defenses. In addition, Occidental argues that, due to their conduct

in the first lawsuit, Wausau and the American Underwriters are estopped from now asserting their

cross-claim.

Summary judgment on the waiver and estoppel theories advance d by Occidental is not

appropriate. With regard to Occidental's waiver theory, the undisputed facts demonstrate that

Wausau and the American Underwriters did not "voluntarily" pay the loss, but instead paid under a

reservation of rights. Moreover, with regard to the estoppel argument, there are clearly fact issues

regarding Occidental's alleged reliance on representations and/or conduct by Wausau and the

American Underwriters.

VII. CONCLUSION

The district court did not err in granting summary judgment in favor of Occidental. Although

Occidental is not entitled to summary judgment on the ground that (a) the Stands t ill Agreement

precludes the cross-claim, (b) it complied with the absolute implied warranty of seaworthiness at the

inception of the time hull policy, (c) the loss was covered under the Separate Policy o f Insurance

Treatment Clause in the policy, or (d) Wausau and the A merican Underwriters waived or are

estopped to assert this cross-claim, Occidental is entitled to summary judgment on the basis of the

Liner Negligence Clause. Therefore, we AFFIRM the judgment of the district court in favor of

Occidental.
