U.S. Shipping Partners L.P. Notes to Unaudited Condensed Consolidated Financial Statements (in thousands, except per unit data)

1.      Nature of Operations

U.S. Shipping
Partners L.P. (the Partnership) owns and operates several types of
vessels, including six integrated tug barge units (ITBs), three
chemical product, or parcel, tankers (Parcel Tankers) and a product
tanker (Houston).  Additionally, the Partnership has contracted
to construct three articulated tug barges (ATBs) that are scheduled
for delivery in first quarter 2007, August 2008, and November 2008.  The
Partnership and its predecessor company have engaged, since 2002, in
transportation services between ports in the United States, principally for
refined petroleum products and petrochemical and commodity chemical products.
The vessels operate under the regulatory provisions of the Jones Act.

The Partnerships general partner holds a 2% general partner interest and certain incentive distribution rights in the Partnership.  Incentive distribution rights represent the right to receive an increasing percentage of cash distributions after the minimum quarterly distribution, any cumulative arrearages on common units, and certain target distribution levels have been achieved.  The Partnership is required to distribute all of its available cash from basic surplus, as defined in the Partnership agreement.  The target distribution levels entitle the general partner to receive 15% of quarterly cash distributions in excess of $0.50 per unit until all unitholders have received $0.575 per unit, 25% of quarterly cash distributions in excess of $0.575 per unit until all unitholders have received $0.70 per unit, and 50% of quarterly cash distributions in excess of $0.70 per
unit.

In the opinion of management, these financial statements reflect all adjustments necessary, consisting of normal recurring entries, for a fair statement of the financial results of such interim periods.  The results of operations for interim periods are not necessarily indicative of the results of operations to be expected for a full year.  These financial statements should be read together with the consolidated financial statements and notes thereto included in the Partnerships Annual Report on Form 10-K for the year ended December 31, 2005 (the Form 10-K).  The year-end condensed financial statement data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America.

2.       Net Income per Unit

Basic net income per unit is determined by dividing net income, after deducting the amount of net income allocated to the general partners interest, by the weighted average number of units outstanding during the period.  Diluted net income per unit is calculated in the same manner as net income per unit, except that the weighted average number of outstanding units is increased to include the dilutive effect of outstanding unit options or phantom units.  There were no options or phantom units outstanding during the periods ended March 31, 2006 and 2005.

3.      Vessels and Equipment

Vessels and equipment consists of the following:

Depreciation
of vessels and equipment for the periods ended March 31, 2006 and 2005 was
$5,496 and $4,939, respectively.  Amortization of drydocking expenditures
was $2,162 and $1,244 for the periods ended March 31, 2006 and 2005,
respectively.  Construction-in-progress at March 31, 2006 and December 31,
2005 includes amounts paid for the construction of ATBs (Note 7) and capitalized
interest of $1,662 and $1,140, respectively.  Capitalized drydock and
construction expenditures of $2,082 and $6,041 were accrued at March 31, 2006
and December 31, 2005, respectively.

Capitalized drydock expenditures include expenditures for drydocks in progress.  Currently, the Sea Venture drydock is in progress and is estimated to be placed in service in May 2006.  The total cost of the drydock is expected to be $9,300, of which $3,268 has been paid at March 31, 2006.

4.      Hess Support Agreement

On September 13, 2002, the Partnership entered into an agreement (the Support Agreement) with Hess in which certain daily charter rates were agreed for five years and based upon which support payments would be made by Hess to the Partnership.  Under the terms of the Support Agreement, Hess agreed to pay the Partnership for the amount by which the Partnerships negotiated third-party contract rates are less than the agreed charter rate. However, in the event that the charter rates the Partnership receives on the ITBs are in excess of the Hess support rate, then the Partnership must pay such excess amounts to Hess until the Partnership has repaid Hess for all prior support payments made by Hess to the Partnership, and then the Partnership must share 50% of any additional excess amount with Hess. The differences resulting from these rates are calculated on a monthly basis. The net
amounts received or paid by the Partnership will be considered contingent purchase price until the end of the Support Agreement term (September 2007), at which time the net amount received or paid will be treated as a purchase price adjustment.

From September 13, 2002 to March 31, 2006, the cumulative amount of payments made by Hess, net of amounts paid to Hess were $13,254, which are classified as advances from Hess.  Based on current contracts and projected revenue rates through 2007, the Partnership estimates that the net

##### 

cumulative payments received from Hess pursuant to the support agreement will be approximately $5,000 to $10,000 and will result in a reduction of the carrying value of the ITBs as an adjustment of their original purchase price.

5.      Financing

During the three months ended March 31, 2006, to finance a portion of the construction of its ATB series, the Partnership borrowed $10,000 from its $50,000 revolving credit facility.   These borrowings bear interest at LIBOR plus 2.00%, or 6.98% at March 31, 2006, and are classified as short-term borrowings.  At March 31, 2006, the Partnerships remaining available credit on its revolving credit facility was $39,400.

6.      Related Party Transactions

Hess is one of the Partnerships significant customers. Voyage revenues earned from transactions with Hess (which do not include amounts under the Support Agreement) for the periods ended March 31, 2006 and 2005 were $3,150 in each period.  The Partnership had a payable to Hess under the support agreement of $528 at March 31, 2006 and a receivable from Hess of $344 at December 31, 2005.

Certain subsidiaries of the predecessor of the Partnership were not contributed to the Partnership; however, these subsidiaries expenses are entirely reimbursable by the Partnership.  Amounts reimbursable to these subsidiaries include general and administrative expenses, and wages and benefits for crew members.  These amounts were $10,700 and $8,711, respectively, for the periods ended March 31, 2006 and 2005.

On September 23, 2005, the Partnership entered into a new ten-year lease for office space for our New York City office.  The Partnership subleases 75% of the leased space to certain companies affiliated with the Chairman and Chief Executive Officer of the Partnership.  The affiliated companies will pay their portion of the rent in advance of the Partnership making the rental payment.  The Partnership has provided a letter of credit totaling $214 to secure final payments of the lease commitment.  The Partnership has been reimbursed 75% of the cost of providing the letter of credit and has received a guaranty from its Chairman in the event of any default of the lease, including that which would require drawdown of the letter of credit.

7.      Commitments and Contingencies

ATB Contracts

In November 2005, the Partnership amended its contract with Southern New England
Shipyard Company (SENESCO) to build a 19,999 dwt articulated tug barge (ATB)

##### 

bringing the total cost of completion of the ATB to $53.4 million, with a scheduled delivery date of December 2006.  SENESCO has indicated that it is still experiencing cost overruns and further delays in completing the ATB.  The Partnership now expects the ATB to be delivered during the first quarter of 2007 at an additional cost of approximately $26 million-$28 million. SENESCO has posted letters of credit totaling $18 million to fund cost overruns on the ATB.  The Partnership is presently involved in negotiations with SENESCO and its principal shareholder to cover cost overruns, to identify means to accelerate construction and to avoid further delays, which could include the Partnership taking over management and completion of the construction.  If negotiations are not successful, the Partnership intends to vigorously pursue all remedies available.  The Partnership cannot assure unitholders at this time that our negotiations with
SENESCO will be successful or that the ATB will be completed on the revised schedule and at the revised cost, or at all.

On February 16, 2006, the Partnership entered into contracts to construct two additional ATBs with Manitowoc Marine Group (MMG) and Eastern Shipbuilding Group, Inc. (Eastern).  The total construction price for the two ATBs is anticipated to be approximately $130,000, or $65,000 per unit, including owner furnished items.  Additionally, the Partnership has committed to purchase owner-furnished items related to two additional vessels for which the Partnership has options totaling $17,498.  At March 31, 2006, the Partnership has made payments totaling $11,464 related to these new builds.

The contracts to construct our ATBs with MMG and Eastern are primarily fixed, however there is an escalator clause related to the price of steel.  The contract is priced utilizing a steel cost of $900/ton for steel plate and $1,100/ton for steel shape.  Increases or decreases from these stated costs could significantly impact the cost of the vessels.

Tanker Project

On March 15, 2006, the Partnership made a $5,000 deposit to reserve shipyard slots for the building of new vessels, of which $4,600 is refundable if the Board of Directors of the General Partner of the Partnership elects by May 26, 2006 not to proceed with the building of the new vessels.

At March 31, 2006, we had received advance payments of $2,270 for freight revenue from a customer.  This deferred revenue is classified as a liability until earned.  No advance payments were made at December 31, 2005.

Financing

Due to the commitments to construct ATBs at MMG and Eastern, the Partnership has secured a commitment from its existing lender to refinance its existing credit facility to increase availability of funds by up to $95,000, if needed.   Management is exploring with its advisors various funding alternatives for its ATB  construction program. The
Partnership will incur a fee related to this refinancing ranging from $2,500 to
$5,000, if exercised.  The credit facility commitment, if unexercised,
expires June 30, 2006.  If the Partnership is unable to consummate the refinancing, the Partnership would have to explore other
alternatives to financing the new buildings or scale back the new building program.

8.      Other Comprehensive Income

The Partnership uses interest rate swaps as required under the terms of its credit facility.  The Partnerships policy is to manage interest costs using a mix of fixed and variable rate debt.  The Partnership holds two interest rate swaps with notional amounts of $23,063 and $60,688 that effectively converted the floating LIBOR-based payments of its credit facility to a fixed rate of 3.15% plus 2.0%, and 3.9075% plus 2.0%, respectively. These contracts expire in December 2006 and 2008, respectively.  The unrealized gain related to interest rate hedges was $2,413 at March 31, 2006 and $1,869 as of December 31, 2005.   These amounts are reflected in other comprehensive gain as the contracts have been designated as cash flow hedges.

The
Partnership has entered into contracts for the purchase of owner-furnished items
relative to the Partnerships newbuild ATB series, denominated in Euros,
costing approximately $14,439.  To hedge the exposure to foreign currency,
the Partnership has entered into a series of foreign currency forward contracts
with an average exchange rate of $1.25/Euro. The fair market value of the forward contract at March 31, 2006 was $60.

9.      Subsequent Events

On May 2, 2006, the Board of Directors of the general partner declared and the Partnership announced its regular cash distribution for the first quarter of 2006 of $0.45 per unit. The distribution will be paid on all common, subordinated and general partner units on May 15, 2006 to all unitholders of record on May 10, 2006. The aggregate amount of the distribution will be $6,337.

On April 6, 2006, the Partnership paid $3,831 to Manitowac Marine Group to extend its option to build two additional barges, of which $3,331 is refundable if the option is not exercised by May 17, 2006.

To finance a
portion of construction costs related to the Partnerships ATB series, the Partnership drew
down two loans from its revolving credit facility on April 10, 2006 and April
28, 2006, of $5,000 each.  These borrowings bear interest at LIBOR plus
2.00%, or 7.023% and 7.059%, respectively.  At May 9, 2006, the
Partnerships remaining available credit on its revolving credit facility
was $29,400.

|ITEM 2. | Managements Discussion and Analysis of Financial Condition and   Results of Operations
|------- | ---------------------------------------------------------------------------------------

Overview

We are a leading provider of long-haul marine transportation services, principally for refined petroleum products, in the U.S. domestic coastwise trade. We are also involved in the coastwise transportation of petrochemical and commodity chemical products. Marine transportation is a vital link in the distribution of refined petroleum, petrochemical and commodity chemical products in the United States, with approximately 28% of domestic refined petroleum products being transported by water in 2004. Our fleet consists of ten vessels: six integrated tug barge units, or ITBs, one product tanker, and three specialty refined petroleum and chemical product, or parcel, tankers. Our primary customers are major oil and chemical companies. A significant portion of our fleet capacity is currently committed to these companies pursuant to contracts with initial terms of one year or more, which provides us
with a relatively predictable level of cash flow. We do not assume ownership of any of the products that we transport on our vessels.

Our market is largely insulated from direct foreign competition because the Merchant Marine Act of 1920, commonly referred to as the Jones Act, restricts U.S. point-to-point maritime shipping to vessels operating under the U.S. flag, built in the United States, at least 75% owned and operated by U.S. citizens and manned by U.S. crews. All of our vessels are qualified to transport cargo between U.S. ports under the Jones Act.

We generate revenue by charging customers for the transportation and distribution of their products utilizing our vessels. These services are generally provided under the following four basic types of contractual relationships:

| |  | time   charters, which are contracts to charter a vessel for a fixed period of time,   generally one year or more, at a set daily rate;                                                          
| | - | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
| |   |                                                                                                                                                                                                  
| |  | contracts of   affreightment, which are contracts to provide transportation services for   products over a specific trade route, generally for one or more years, at a   negotiated rate per ton;
| |   |                                                                                                                                                                                                  
| |  | consecutive   voyage charters, which are charters for a specified period of time at a   negotiated rate per ton; and                                                                             
| |   |                                                                                                                                                                                                  
| |  | spot   charters, which are charters for shorter intervals, usually a single   round-trip, that are made on either a current market rate or lump sum   contractual basis.                         

The principal difference between contracts of affreightment and consecutive voyage charters is that in contracts of affreightment the customer is obligated to transport a specified minimum amount of product on our vessel during the contract period, while in a consecutive voyage charter the customer is obligated to fill the contracted portion of the vessel with its product every time the vessel calls at its facility during the contract period and, if the customer does not have product ready to ship, it must pay us for idle time.

The table below illustrates the primary distinctions among these types of contracts:

|                            |  | Time Charter                                                  |  | Contract ofAffreightment |  | Consecutive Voyage Charter         |  | Spot Charter

For the three months ending March 31, 2006 and 2005, we derived approximately 75% and 66%, respectively, of our revenue under time charters, consecutive voyage charters and contracts of affreightment, and approximately 25% and 34%, respectively, of our revenue from spot charters.

The amounts received from or paid to Hess pursuant to the Hess support agreement are not recognized as revenue or expense but are deferred for accounting purposes and will be reflected as an adjustment to the purchase price relating to the acquisition of the ITBs.

On February
16, 2006, we entered into a contract with Manitowoc Marine Group
(MMG) for the construction of two barges, which are specified to
have a carrying capacity of approximately 160,000 barrels each at 98% of
capacity. The contract with MMG includes options to construct two additional
barges, for which we paid $3.8 million on April 6, 2006 to extend the option to
May 17, 2006.    If we do not elect to proceed with the
construction of the two additional barges, we will receive a refund of $3.3
million from MMG.  If we elect to proceed with the construction of the two
additional barges, the deposit will be applied to the contract price.  On
February 16, 2006, we also entered into a contract for the construction of two
tugs with Eastern Shipbuilding Group, Inc. (Eastern), which will be
joined with the barges to complete the two ATB units. The contract with Eastern
also includes options to construct and deliver up to four additional ATB tugs on
the basis that each such option shall cover an order for two tugs. The total
construction price for the two ATBs is anticipated to be approximately $130
million, or $65 million per unit.  The total construction price for the
third and fourth option ATBs is anticipated to be $132 million, or $66 million
per unit. We expect the first two ATBs will be completed in August 2008 and
November 2008, and the third and fourth option ATBs, if exercised, will be
completed in August 2009 and November 2009, respectively.  The options for
the tugs, which must be exercised by August 2006 and February 2007, remain
unexercised at the time of this filing.  Due to the commitments to construct ATBs at MMG and Eastern, we have secured a commitment from our existing lender to refinance our existing credit facility to increase availability of funds by up to $95.0 million, if needed.   We are exploring with our advisors various funding alternatives for our ATB construction program.  The
credit facility commitment, if unexercised, expires June 30, 2006. We will incur a fee related
to this refinancing ranging from $2.5 million to $5.0 million, if exercised. If we are unable to
consummate the refinancing, we would have to explore other alternatives to
financing our new buildings or scale back our new building program.

In November 2005, we amended our contract with Southern New England Shipyard Company

##### 

(SENESCO) to build a 19,999 dwt articulated tug barge (ATB) bringing the total cost of completion of the ATB to $53.4 million, with a scheduled delivery date of December 2006.  SENESCO has indicated that it is still experiencing cost overruns and further delays in completing the ATB.  We now expect the ATB to be delivered during the first quarter of 2007 at an additional cost of approximately $26 million-$28 million. SENESCO has posted letters of credit totaling $18 million to fund cost overruns on the ATB.  We are presently involved in negotiations with SENESCO and its principal shareholder to cover cost overruns, to identify means to accelerate construction and to avoid further delays, which could include our taking over management and completion of the construction.  If
negotiations are not successful, we intend to vigorously pursue all remedies available to us.  We cannot assure unitholders at this time that our negotiations with SENESCO will be successful or that the ATB will be completed on the revised schedule and at the revised cost, or at all.

On March 15, 2006, we made a $5.0 million deposit to a shipyard to reserve shipyard slots for new build tanker vessels, of which $4.6 million is refundable if we elect not to proceed by May 26, 2006.    We may elect to finance this new build series through off-balance sheet financing.

Definitions

In order to understand our discussion of our results of operations, it is important to understand the meaning of the following terms used in our analysis and the factors that influence our results of operations:

| |  | Voyage revenue. Voyage revenue includes   revenue from time charters, contracts of affreightment, consecutive voyage   charters and spot charters. Voyage revenue is impacted by changes in charter   and utilization rates and by the mix of business among the types of contracts   described in the preceding sentence.                                                                                                                                                                                                                                                                                                                                                                                                                        
| | - | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
| |   |                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
| |  | Voyage expenses. Voyage expenses include   items such as fuel, port charges, pilot fees, tank cleaning costs, canal   tolls and other costs which are unique to a particular voyage. These costs   can vary significantly depending on the voyage trade route. Depending on the   form of contract, either we or our customer is responsible for these   expenses. If we pay voyage expenses, they are included in our results of   operations when they are incurred. Typically, our freight rates are higher   when we pay voyage expenses. Our contracts of affreightment and consecutive   voyage charters generally contain escalation clauses whereby certain cost   increases, including labor and fuel, can be passed on to our customers.
| |   |                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
| |  | Vessel operating expenses. We pay the vessel   operating expenses regardless of whether we are operating under a time   charter, contract of affreightment, consecutive voyage charter or spot   charter. The most significant direct vessel operating expenses are crewing   costs, vessel maintenance and repairs, bunkers and lube oils and marine   insurance.

| |  | Drydocking days. Drydocking days are days   designated for the inspection and survey of vessels, and resulting   maintenance work, as required by the U.S. Coast Guard and the American Bureau   of Shipping to maintain the vessels qualification to work in the U.S.   coastwise trade. Both domestic (U.S. Coast Guard) and international (International   Maritime Organization) regulatory bodies require that our ITBs be drydocked   for major repair and maintenance every five years, with a mid-period   underwater survey in lieu of drydocking, and our parcel tankers be drydocked   twice every five years. Drydocking days also include unscheduled instances   where vessels may have to be drydocked in the event of accidents or other   unforeseen damage.

| |  | Net utilization. Net utilization is a   primary measure of operating performance in our business. Net utilization is   a percentage equal to the total number of days worked by a vessel or group of   vessels during a defined period, divided by total vessel days for that vessel   or group of vessels. Net utilization is adversely impacted by drydocking,   scheduled and unscheduled maintenance and idle time not paid for by the   customer.

| |  | Time charter equivalent. Time charter   equivalent, another key measure of our operating performance, is equal to the   net voyage revenue earned by a vessel during a defined period, divided by the   total number of actual days worked by that vessel during that period.   Fluctuations in time charter equivalent result not only from changes in   charter rates charged to our customers, but from external factors such as   weather or other delays.

U.S. Shipping Partners L.P. Unaudited Other Financial Data (in thousands)

Three Months Ended March 31, 2006 Compared to Three Months Ended March 31, 2005

Voyage Revenue.  Voyage revenue was $37.0 million for the three months ended March 31, 2006, an increase of $4.0 million, or 12%, as compared to $33.1 million for the three months ended March 31, 2005.  The increase is principally attributable to the addition of the Houston, which we purchased in September 2005, and which contributed $4.2 million of revenue.  A decrease in ITB revenue of $1.8 million was partially offset by an increase in revenue for our chemical vessels of $1.5 million.  The decrease in ITB revenue was attributable to a reduction in demand for spot vessels due to a warmer winter and a decrease in refinery output due to lingering effects of hurricanes, coupled with a reduction in utilization caused by unplanned maintenance to one of our vessels.  The increase in the chemical vessel revenue was attributable to rate increases, improved voyage
turnaround time and additional backhaul revenue resulting from competing vessels being out of service for drydocking during the 2006 quarter.

Vessel Operating Expenses.    Vessel operating expenses were $13.6 million for the three months ended March 31, 2006, an increase of $2.7 million, or 24%, as compared to $10.9 million for the three months ended March 31, 2005.  The addition of the Houstonadded $1.7 million of vessel operating expenses during the quarter and the addition of the Sea Venture, though not placed in service, resulted in $0.3 million of vessel operating expenses, principally comprised of crew wages and benefits for two crew members currently on the vessel while it is undergoing drydocking.  The remaining increase was primarily caused by the addition of a third mate to the crew complements of the ITBs due to Coast Guard regulations coupled with contracted crew wage and benefit increases.

Voyage Expenses.   Voyage expenses were $7.3 million for the three months ended March 31, 2006, an increase of $1.3 million, or 21%, as compared to $6.1 million for the three months ended March 31, 2005.  The addition of the Houstoncontributed $1.1 million of the increase.  The remaining increase is principally attributable to increased bunker expense due to rising fuel costs.

General and Administrative Expenses.   General and administrative expenses were $2.8 million for the three months ended March 31, 2006, an increase of $0.5 million, or 20%, as compared to $2.4 million for the three months ended March 31, 2005.  The increase is attributable to increases in personnel, accounting and legal expenses as well as costs incurred pursuing acquisitions and growth opportunities for our business.

Depreciation and Amortization.  Depreciation and amortization was $7.7 million for the three months ended March 31, 2006, an increase of $1.5 million, or 24%, compared to $6.2 million for the three months ended March 31, 2005.  Approximately $0.9 million of the increase is attributable to the addition of the Houston, which we acquired in September 2005 for $25.3 million and placed in service in October 2005 upon completion of its drydocking, which cost approximately $3.1 million. The

17



---



##### 

remaining increase is attributable to the amortization of drydocking expenditures related to the New Yorkand Jacksonville, which were completed at a cost of approximately $6.0 million each in November and December 2005, respectively.

Interest Expense.  Interest expense was $1.6 million for the three months ended March 31, 2006, an increase of $0.2 million, or 13%, compared to $1.4 million for the three months ended March 31, 2005.  The increase is attributable to higher average outstanding debt balance during the first quarter 2006 offset by an increase in capitalized interest and amortization of debt financing fees.

Benefit for Income Taxes.  The benefit for income taxes for the quarters ended March 31, 2006 and 2005 is attributable to pre-tax operating loss in our corporate subsidiary, principally caused by depreciation of the extensive 2003 drydock of the Chemical Pioneer.

Net Income.  Net income was $4.2 million for the three months ended March 31, 2006, a decrease of $2.4 million, or 37%, compared to $6.6 million for the three months ended March 31, 2005.  The decrease is attributable to a decrease in operating income of $1.9 million primarily related to amortization of the recently completed drydockings of the New York and Jacksonville coupled with lower time charter equivalent rates and increases in vessel operating and general and administrative expenses, partially offset by increased operating income contributed by the Houston.   An increase in interest expense and decrease in benefit for income taxes of $0.2 million and $0.3 million, respectively, also contributed to the decrease in net income.

Liquidity and Capital Resources

Operating Cash Flows

Net cash provided by operating activities was $8.0 million for the three months ended March 31, 2006, a decrease of $7.1 million, or 47%, compared to $15.1 million for the three months ended March 31, 2005.  The decrease is primarily the result of a $9.2 million increase in drydock expenditures, $0.4 million decrease in operating results, (after adjusting for non-cash expenses such as depreciation and amortization), a $0.3 million increase in current income taxes and a $0.1 million increase in cash interest expense, net of interest income, due to an increase in higher average debt balances, partially offset by a $2.9 million favorable working capital fluctuation.

Investing Cash Flows

Net cash used in investing activities totaled $15.6 million for the three months ended March 31, 2006, an increase of $9.3 million, or 148%, compared to $6.3 million for the three months ended March 31, 2005.  During the first quarter 2006, we made $3.9 million of progress payments toward the construction of our first ATB and $7.7 million of payments toward the construction costs of our second and third ATBs.  Additionally, in March 2006, we paid a $5.0 million deposit to secure shipyard slots to build tankers, of which $4.6 million is refundable through May 26, 2006.  During the first quarter 2005, we made $6.1 million of progress payments toward the construction of our first ATB.

The
amounts received from or paid to Hess pursuant to the Hess support agreement are
not recognized as revenue or expense but are deferred for accounting purposes
and will be reflected as an adjustment to the purchase price of the ITBs from
Hess at the end of the Hess support agreement. Pending such adjustment, they are
included in cash flows from investing activities as advances from (payments to)
Hess. If the rate for an ITB exceeds the support rate set forth in the support
agreement, we must pay the excess to Hess to reimburse Hess for any payments
made to us by Hess under the support agreement.  Once Hess has been fully
reimbursed for all payments made under the support agreement, we must pay Hess
50% of any remaining excess.  Advances from Hess under the support
agreement were $0.9 million for the three months ended March 31, 2006. 
Payments to Hess under the support agreement were $0.2 million for the
three months ended March 31, 2005.  For the three months ended March 31,
2006 and 2005, five ITBs were covered by the support agreement.  One ITB is
under contract with Hess at a charter rate less than the support rate. 
This vessel will be covered by the support agreement upon any termination of
that contract.

Financing Cash Flows

Net cash provided by financing activities was $3.2 million for the three months ending March 31, 2006 and net cash used in financing activities was $4.4 million for the three months ended March 31, 2005.  We borrowed $10.0 million under the revolver portion of our credit facility to finance the construction of the ATB series and fund a deposit for a shipyard slot to build tankers.  For the three months ended March 31, 2006 and 2005 we made scheduled debt repayments of $0.5 million and $0.4 million, respectively.  We paid $6.3 million and $4.1 in distributions to partners during the three months ended March 31, 2006 and 2005, respectively.  See Payments of Distributions below.

Payments of Distributions

The board of directors of US Shipping General Partner LLC, our general partner, declared a quarterly distribution to unitholders of $0.45 per unit in respect of the quarter ended December 31, 2005, which was paid on February 15, 2006 to unitholders of record on February 10, 2006.  The distribution paid on February 9, 2005, declared in respect of the quarter ended December 31, 2004 of $0.2885 per unit, was a pro ration of the $0.45 minimum quarterly distribution for the period that the Partnership was publicly traded, November 3, 2004 through December 31, 2004.

Ongoing Capital Expenditures

Marine transportation of refined petroleum, petrochemical and commodity chemical products is a capital intensive business, requiring significant investment to maintain an efficient fleet and to stay in regulatory compliance. Both domestic (U.S. Coast Guard) and international (International Maritime Organization) regulatory bodies require that our ITBs and ATBs be drydocked for major repairs and maintenance every five years and that we conduct a mid-period underwater survey in lieu of drydocking, and that our parcel tankers and the Houston be drydocked twice every five years. In addition, vessels may have to be drydocked in the event of accidents or other unforeseen damage. Periodically, we also make expenditures to acquire or construct additional tank vessel capacity and/or to upgrade our overall fleet efficiency.

During 2005, we placed three vessels, the newly purchased Houston, the New Yorkand the

Jacksonville,in drydock.  The Houstondrydock was completed in October 2005 at a cost of $3.1 million.  The ITB New Yorkdrydock was completed in November at a cost of $6.1 million and the ITB Jacksonville was completed in December at a cost of $6.0 million.  In January 2006, the Sea Venturewas placed in drydock at an estimated cost of $9.3 million and is currently scheduled to be completed in May 2006.  During 2006, the parcel tankers Charleston and Chemical Pioneer and the ITBs Grotonand Mobilewill also be placed in drydock with a total estimated cost of $19.0 million.  The Baltimoreand Philadelphiaare scheduled for drydock in 2007.  For future drydockings, we estimate that drydocking the ITBs will cost approximately $6.0 million per vessel, the parcel tanker drydocks will cost approximately $3.0 million to $5.0 million per vessel, the Houstondrydock will cost approximately $3.0 million and the ATB drydockings will cost between $1.0 million and $2.0 million.  While drydocked, each of our ITBs will be out of service for approximately 50 to 60 days, each parcel tanker and the Houstonwill be out of service for approximately 35 to 50 days and the ATBs will be out of service for approximately 25 days. At the time we drydock these vessels, the actual cost of drydocking may be higher due to inflation and other factors.  In addition, vessels in drydock will not generate any income, which will reduce our revenue and cash available for distribution.

Our partnership agreement requires our general partner to deduct from basic surplus each quarter estimated maintenance capital expenditures as opposed to actual maintenance capital expenditures in order to reduce disparities in basic surplus caused by fluctuating maintenance capital expenditures, such as retrofitting or drydocking.  Our annual estimated maintenance capital expenditures for purposes of calculating basic surplus increased from $17.2 million in 2005 to $19.6 million in 2006. This amount is based on our current estimates of the amounts of expenditures we will be required to make in the future, which we believe to be reasonable. The amount of estimated maintenance capital expenditures deducted from basic surplus is subject to review and change by the board of directors of our general partner at least once a year, with any change approved by the conflicts committee.

The following
table summarizes total maintenance capital expenditures, consisting of drydocking expenditures, and expansion capital expenditures for the
periods presented (in thousands):

Liquidity Needs

Our primary short-term liquidity needs are to make scheduled debt payments, pay our quarterly distributions, make progress payments related to our new build ATBs, and to fund general working capital requirements and drydocking expenditures.  Our long-term liquidity needs are primarily associated with expansion and other maintenance capital expenditures. Expansion capital expenditures are primarily for the purchase or construction of vessels, including the ATBs currently under

construction.  Maintenance capital expenditures include drydocking expenditures and the cost of bringing our vessels into compliance with OPA 90. Our primary sources of funds for our short-term liquidity needs will be cash flows from operations and borrowings under our credit facility.  Our long-term sources of funds will be from cash from operations, long-term bank borrowings and other debt or equity financings.

Due to the commitments to construct ATBs at MMG and Eastern, we have secured a commitment from our existing lender to refinance our existing credit facility to increase availability of funds by up to $95.0 million, if needed.   We are exploring with our advisors various funding alternatives for our ATB construction program. We will incur a fee related to this refinancing ranging from $2.5 million to $5.0 million,
if exercised. The credit facility commitment if unexercised, expires June 30,
2006. If we are unable to consummate the refinancing, we would have to explore
other alternatives to financing our new buildings or scale back our new building
program.  If our plans or assumptions change or are inaccurate, or we make any additional
acquisitions, we may need to raise additional capital to finance our ongoing
construction projects on a long-term basis, which financing may be on an
off-balance sheet basis and/or through the incurrence of additional debt. There
can be no assurance that we will be able to raise additional funds on favorable
terms.

|ITEM 3. | Quantitative and Qualitative Disclosures   about Market Risk
|------- | ------------------------------------------------------------

Our market risk is affected primarily by changes in interest rates. We are exposed to the impact of interest rate changes primarily through our variable-rate borrowings under our credit facility. Significant increases in interest rates could adversely affect our profit margins, results of operations and our ability to service our indebtedness. Based on our average variable interest rate debt outstanding during the first quarter of 2006, a 1% change in our variable interest rates would have increased our interest expense by $0.1 million for the first quarter 2006, after taking into effect the interest rate swap agreement we had in effect  as described below.

We utilize interest rate swaps to reduce our exposure to market risk from changes in interest rates. The principal objective of such contracts is to minimize the risks and/or costs associated with our variable rate debt. All derivative instruments held by us are designated as hedges and, accordingly, the gains and losses from changes in derivative fair values are recognized as comprehensive income as required by SFAS 133. Gains and losses upon settlement are recognized in the statement of operations or recorded as part of the underlying asset or liability as appropriate. We are exposed to credit-related losses in the event of nonperformance by counterparties to these financial instruments; however, counterparties to these agreements are major financial institutions, and the risk of loss due to nonperformance is considered by management to be minimal. We do not hold or issue interest rate swaps for
trading purposes.

We had two open interest rate swap agreements as of March 31, 2006.  The intent of these agreements is to reduce interest rate risk by swapping an unknown variable interest rate for a fixed rate. The following is a summary of the economic terms of these agreements at March 31, 2006:

| | Expiration   date        | 12/31/2008     |   | 

We have
entered into contracts for the purchase of owner-furnished items relative to our
newbuild ATB series, denominated in Euros, costing approximately $14.4 million.  To hedge the exposure to foreign currency, we have entered into a
series of foreign currency forward contracts with an average exchange rate of
$1.25/Euro.

The contracts to construct our ATBs with Manitowac and Eastern are primarily fixed; however there is an escalator clause related to the price of steel.  The contract is priced utilizing a steel cost of $900/ton for steel plate and $1,100/ton for steel shape.  The impact of an increase in steel prices of $100/ton would increase the cost of construction by $0.4 million per vessel.

|ITEM 4. | Controls and Procedures
|------- | -----------------------

In accordance with Exchange Act Rules 13a-15 and 15d-15, we carried out an evaluation, under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report.  Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of March 31, 2006 to provide reasonable assurance that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commissions rules and forms.

There has been no change in our internal control over financial reporting that occurred during the three months ended March 31, 2006 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART IIOTHER INFORMATION

|ITEM 1. | Legal Proceedings
|------- | -----------------

The Partnership is subject to various claims and lawsuits in the ordinary course of business for monetary relief principally from personal injuries, collision or other casualty and to claims arising under vessel charters.   Although the outcome of any individual claim or action cannot be predicted with certainty, we believe that any adverse outcome, individually or in the aggregate, would be substantially mitigated by applicable insurance or indemnification from previous owners of our assets, and would not have a material adverse effect on our financial position, results of operations or cash flows.  We are subject to deductibles with respect to our insurance coverage which range up to $150,000 per incident, and we provide on a current basis for estimated payments thereunder.

|ITEM 1A. | Risk Factors
|-------- | ------------

The following information updates the risk factors set forth in Item 1A. of our Annual Report on Form 10-K for the year ended December 31, 2005:

In August
2004, we entered into a contract with Southern New England Shipyard Company
(SENESCO) to build a 19,999 dwt articulated tug barge
(ATB) at a cost of $45.4 million with a scheduled delivery date of
April 2006.The agreement also provided for options to build up to three
additional ATBs. SENESCO had indicated that they were not able to complete the
first ATB on the contract terms due to infrastructure problems and production
line issues, and that the completion of the barge would be
delayed.  In November 2005, we amended our contract with SENESCO
bringing the total cost of completion of the ATB to $53.4 million, with a
scheduled delivery date of December 2006, and cancelled the options. SENESCO has
indicated that it is still experiencing cost overruns and further delays in
completing the ATB.  We now expect the ATB to be delivered during the first
quarter of 2007 at an additional cost of approximately $26 million-$28
million. SENESCO has posted letters of credit totaling $18 million to fund
cost overruns on the ATB.  We are presently involved in negotiations with
SENESCO and its principal shareholder to cover cost overruns, to identify means
to accelerate construction and to avoid further delays, which could include our
taking over management and completion of the construction.  If negotiations
are not successful, we intend to vigorously pursue all remedies available to
us.  We cannot assure unitholders at this time that our negotiations with
SENESCO will be successful or that the ATB will be completed on the revised
schedule and at the revised cost, or at all.  To the extent we take over
management and completion of construction of the SENESCO ATB, this will decrease
the amount of time our officers can devote to our business.

Certain of our customers have indicated they are not interested in chartering retrofitted ITBs, which could affect our strategy to make the ITBs OPA-90 compliant.

Our general partner has elected Gerald Luterman, Executive Vice President and Chief Financial Officer of KeySpan Corporation, to the Board of Directors of our general partner as an independent director.  Keyspan Corporation is the fifth largest distributor of natural gas in the United States and the largest in the Northeast, operating regulated gas utilities in New York, Massachusetts, and New Hampshire that serve 2.6 million customers.  Mr. Luterman has a Masters in Business Administration from Harvard Business School where he was a Baker Scholar. He is a graduate of McGill University in Montreal and earned a Bachelor of Commerce Degree with honors in economics.

In November 2005, we amended our contract with Southern New England Shipyard Company (SENESCO) to build a 19,999 dwt articulated tug barge (ATB) bringing the total cost of completion of the ATB to $53.4 million, with a scheduled delivery date of December 2006.  SENESCO has indicated that it is still experiencing cost overruns and further delays in completing the ATB.  We now expect the ATB to be delivered during the first quarter of 2007 at an additional cost of approximately $26 million-$28 million. SENESCO has posted letters of credit totaling $18 million to fund cost overruns on the ATB.  We are presently involved in negotiations with SENESCO and its principal shareholder to cover cost overruns, to identify means to accelerate construction and to avoid further delays, which could include our taking over management and completion of the
construction.  If negotiations are not successful, we intend to vigorously pursue all remedies available to us.  We cannot assure unitholders at this time that our negotiations with SENESCO will be successful or that the ATB will be completed on the revised schedule and at the revised cost, or at all.
