Appendix: Commercial Harbor Craft Survey
D - 3

I. Introduction and Background

In December 2002, the Air Resources Board (ARB or Board) conducted the 

Statewide Commercial Harbor Craft Survey (Commercial Harbor Craft Survey or 

survey). The survey was intended to collect information about the various 

commercial harbor craft operating in California's coastal waters, harbors, and ports. 

The information was collected to help update the statewide emissions inventory for 

commercial marine vessels operating in the State. This report provides an overview 

of the results from the survey. A copy of the survey is provided in the appendix.

Commercial harbor craft are vessels used for commercial purposes or to support 

public services.1 There are several types of harbor craft including crew and supply 

boats, charter fishing vessels, commercial fishing vessels, ferry/excursion vessels, 

pilot vessels, towboat or push boats, tug boats and work boats. The Statewide 

Commercial Harbor Craft survey requested vessel owners and operators to submit 

the following information for each commercial harbor craft:

• Vessel name

• U.S. Coast Guard Documentation Number

• Home Port

• Vessel Age

• Vessel Use

• Type of Fishing, (If a fishing vessel)

• Annual Fuel Usage

• Percent of Hours Operated Various Distances Off California Coast

• Auxiliary or Propulsion Engine

• Engine Placement (Port, Starboard, Center)

• Engine Make (manufacturer)

• Engine Model

• 2 or 4 Stroke Engine

• Model year

• Engine Horsepower

• Annual Hours of Operation

• Estimated Fuel Usage (1999, 2000, 2001)

• Wet or Dry Exhaust (Propulsion Engine Only)

The survey was distributed to approximately 5,000 potential owners and operators. 

The majority of the contacts were located in California with a small percentage being 

out-of-state contacts. Addresses of potential harbor craft owners and operators were 

obtained primarily from the U.S. Coast Guard and the California Department of Fish 

and Game. 704 surveys were returned providing data on approximately 900 vessels 

and over 1800 engines. In the following sections, the results for the survey are 

presented including the types of vessels in use, engine specifications (i.e., make, 

model, horsepower) and annual activity of the vessel.

The survey did not collect information on recreational vessels or the larger oceangoing vessels 

generally used to transport cargo. 
D - 4

II. Vessel Information Survey Results

The respondents to the survey were requested to provide information on the vessels 

that they owned or operated including the home port of each vessel, the primary use 

for the vessel, the annual fuel usage and the percent of time the vessel is operated at 

various distances off California's coast. Information for 909 vessels was collected in 

the survey. Not all surveys had data entered for every data field. Blank data fields 

were not included in average or population numbers in the survey summaries.

The majority of the respondents, 66%, reported information for 1 vessel, 17% 

reported owning or operating 2 to 5 vessels and 18% reported owning 6-20 vessels. 

In this section the vessel information described above is summarized. 

Table 1 provides a summary of the home ports for the vessels reported in the survey. 

For the purpose of the survey, home port is defined on the survey as the principal 

place for loading or unloading of passengers, or the loading or unloading of supplies, 

and normally used for the overnight berthing of the vessel. In total there were 99 

home ports identified. Several vessels were reported to have home ports outside of 

California. Out of state ports included Honolulu, Seattle, and Portland. For these 

vessels, follow-up discussions with the vessel owners revealed that, in most cases, 

these vessels spent only a few months out of the year in California waters.

A. Vessel Age

The age of the vessels reported in the survey ranged from 99 years old to new 2002 

vessels, with most vessel types having an average vessel age around 30 years. The 

vessel age for commercial passenger fishing, ferry, crew and work boats were similar 

with a population weighted average age of about 27 years. Commercial fishing and 

tug boats tended to have slightly older vessels, with an average vessel age around 

32 years. Tow boats were the oldest on average at 39 years. In Figure 1, this data is 

summarized with the long vertical lines representing the vessel age range and the 

square dots representing the weighted average vessel age.

B. Vessel Use

The survey requested information on the primary use for each vessel. The following 

types of uses were specified on the survey: 

Commercial Fishing Vessels: Self-propelled vessels dedicated to the search for, and 

collection of, fish for the purpose of sale at market. 

Commercial Passenger Fishing Vessels: Self-propelled vessels for hire by the 

general public (seven or more people) dedicated to the search for, and collection of, 

fish for the purpose of personal consumption. 

Crew and Supply Boats: Self-propelled vessel used for carrying personnel and 

supplies to and from off-shore and in-harbor locations (including, but not limited to, 

off-shore work platforms, construction sites, and other vessels). 

Ferry/Excursion Vessel: A vessel owned, controlled, operated, or managed for public 

use in the transportation of persons or property, except rowboats, sailing boats, 

barges under 20 tons dead weight carrying capacity, and vessels that are under the 

burden of five tons net register and under 30 feet in length. 

Pilot Vessels: Self-propelled vessels used to guide ocean-going vessels safely into 

and out of a port or harbor. 

Towboat/Push Boats: Self-propelled vessel designed to tow/push barges and 

pontoons. The hull is usually rectangular in plan and has little freeboard (the portion 

of the side of a hull that is above the water). 

Tug Boats: Self-propelled vessel for the towing (and pushing) of ships or other 

floating structures such as barges in ports/harbors. 

Work Boats: Self-propelled vessel that performs duties such as fire/rescue, law 

enforcement, hydrographic surveys, spill/response, research, training, and 

construction (including drilling) vessels.

Other: Any vessel use that does not fit with the categories identified above. 

As shown in Table 2, commercial fishing and commercial passenger fishing vessels 

are the most commonly reported use for the vessels with approximately 595 or 62% 

of the vessels reporting these uses. Ferry or excursion vessels accounted for 9% of 

the vessels and tugboats, about 8%. 

There are 67 vessels reported as "other." Vessels in the other category included 

vessels used for a variety of uses: excursion/dinner cruises, diving, and sailing boats.

C. Types of Fishing

For fishing vessels the survey also requested the respondent to identify what type of 

fishing is typically done with the vessel. Table 3 lists vessel types and fishing types. 

The survey identified eight common types of fishing techniques used by the 

commercial fishing fleet: drift gill netting (DG net), rakes-air lifts, trolling, set gill 

netting (SG net), trawling, purse seine, trapping and other.

 A single vessel may have reported more than one type of fishing therefore the total number of 

vessels reported in Table 3 will exceed those in Table 2.

D. Annual Fuel Use

The survey requested vessel owners/operators to report the annual fuel used for 

each vessel for the years 1999 through 2001. Table 4 lists the annual fuel used (in 

gallons) by specific harbor craft. In each case, the annual fuel listed is the combined 

usage for propulsion and auxiliary engines. Tug boats had the largest reported fuel 

usage with approximately 5, 374,440 gallons used on average for the years 1999 

through 2001. Overall, there was approximately a 21 percent increase in the amount 

of fuel over the years 1999 to 2001. 3

 The survey collected data on the total annual fuel usege (Form B) per vessel and the annual fuel use 

per engine (Form C). In most cases the total annual fuel useage and annual fuel per engine agreed 

within an average 14%. However, the differences were higher in ferries, tugs, and commercial fishing 

due to many reporting only total annual fuel useage. Total annual fuel useage had a better response 

overall so that was reported. 
D - 10

E. Percent of Hours Operated at Various Distances off the California 

Coast

The Commercial Harbor Craft Survey requested vessel owners provide the percent of 

hours operated at various distances off the California coast. The options were harbor 

operations, 0-25 miles, 26-50, 51-75, 76-100 or greater than 100 miles from the 

California shore. The survey results are presented in Figure 2. Overall, the data 

demonstrated that, for the majority of the time, most commercial harbor craft operate 

within 25 miles of the California coast. 

For example, commercial passenger fishing vessels reported spending over 50% of 

the hours of operation at distances 0-25 miles from shore. The hours operated 

further off shore steadily declined with distance. Nineteen percent of hours were 

spent at 26-50 miles off shore and less than 1% at 76-100 miles. Ferries, in 

comparison, operate 65% of the time in the harbor area and 30% in the 0-25 mile 

zone.

III. Propulsion/Auxiliary Engine Survey Results

For each vessel, the survey requested information on the number, type, and annual 

activity of auxiliary and propulsion engines. Data for 1241 propulsion engines and 

586 auxiliary engines was submitted. In this section summaries are provided of the 

information received on the vessel engine. 

A. Auxiliary Engines

Auxiliary engines are used to power various equipment on-board such as electrical 

lights, refrigeration units and radios. Of the vessels reported in the survey, 40% or 

375 reported having auxiliary engines. For those vessels with auxiliary engines, 56% 

reported having 1 auxiliary engine. Approximately 38% reported having two auxiliary 

engines and five percent reported having three to five auxiliary engines. Data 

provided on auxiliary engines include make and model, model year, horsepower 

data, annual hours of operation and annual fuel usage. As shown in Table 5, the 

horsepower range for auxiliary engines ranged from 6 to 400 horsepower with an 

overall average of about 75 horsepower.

As shown in Figure 3, the most prominent engine manufacturer of vessel auxiliary 

engines from the survey was Detroit Diesel comprising 22% percent of the engines. 

Other more common manufacturers were Isuzu, Northern Lights, Caterpillar, and 

John Deere. Included in the other category were 27 different manufacturers such as, 

Honda, Kubota, and Thermo King. It is possible that some survey respondents may 

have included the name of the manufacturer of the piece of equipment powered by 

the diesel engine as opposed to the actual manufacturer of the engine.
D - 12

Figure 3: Harbor Craft Auxiliary Engine Manufacturers

B. Propulsion Engines

The majority of the vessels had one propulsion engine. 63% of the vessels reported 

having one propulsion engine, 33% had two propulsion engines, and about 3% had 

three or more engines. Data provided on propulsion engines included make and 

model, model year, horsepower data, annual hours of operation, and annual fuel 

usage. As shown in Table 6, the reported horsepower for the propulsion engines 

ranged from 8 to 3,600 horsepower with an overall average of about 500 

horsepower. Tug boats tended to have larger engines with an average of over 1,200 

horsepower.

The most prominent engine manufacturer of vessel propulsion engines from the 

survey was Detroit Diesel comprising 34 percent of the engines. Figure 4 illustrates 

other common manufacturers to be Caterpillar, Cummins and Volvo. Included in the 

other category were 34 different manufacturers such as Bray Marine, International, 

and Deutz. It is possible that some survey respondents may have included the 

engine name other than the actual engine manufacturer, such as a vessel 

manufacturer.

The respondents to the survey were requested to provide information on whether the 

vessels propulsion exhaust was wet or dry. Wet exhaust is exhaust that exits the 

engine under the water, whereas, dry exhaust is emitted into the air, above water. 

Fifty-two percent of the propulsion engines were reported as having dry exhaust and 

forty-six percent wet exhaust. The remaining two percent of the vessels did not have 

the exhaust type specified.

C. Horsepower and Model Year

Table 7 listed below shows the survey population for associated model years and 

horsepower ranges for propulsion engines and auxiliary engines. For both 

propulsion and auxiliary engines, about 80% were 1970 or newer models. About 

10% were pre-1970 model years and roughly 10% did not indicate the engine age.

Figure 5 provides a graphical representation of the vessel and engine model year 

range and average model year reported for each vessel type. In Figure 5, the long 

bar indicates the range model year reported for the vessel (V), propulsion engine (P) 

or auxiliary engine (A) and the rectangular box the population weighted vessel or 

engine average model year for the specified category. While most categories had a 

fairly large range in model years reported, overall, the average age for vessels was 

about 30 years old and the engine average was fairly new, 1980 and newer model 

years.

D. Hours of Operation 

Figure 6 provides information on the average number of hours of operation per year 

for propulsion and auxiliary engines by vessel type. With respect to propulsion 

engine operation, on average, tug boats, commercial fishing boats, and tow boats 

operated the most hours averaging approximately 2,000 hours per year. Crew boats 

and work boats had the lowest average hours of operation reported, at less than 

1,000 hours per year. For auxiliary engines, with the exception of ferries and pilots 

boats, they operated for more hours on a yearly basis than the propulsion engines.

Figure 6: Average Engine Hours of Operation Per Year

For all vessels, the total combined hours of operation for the propulsion engines was 

1,668,000 hours and for auxiliary engines, 975,000 hours. As shown in Figure 7, 

commercial fishing boats reported the highest number of combined hours of 

operation for the propulsion engines at over 550,000 hours annually. Combined, the 

hours of operation of the propulsion engines for commercial fishing, commercial 

passenger fishing, ferries, and tug boats accounted for over 88% of the total hours 

reported. Similarly the hours of operation of the auxiliary in these same vessel 

categories accounted for 85% of the total hours of operation for auxiliary engines 

reported in the survey.

SURVEY OVERVIEW

The Air Resources Board’s (ARB) commercial harbor craft survey is intended to 

collect information about the various commercial harbor craft operating in California’s 

coastal waters, harbors, and ports. This information is being collected to help update 

the emissions inventory for commercial marine vessels operating in the State. 

Below, we have provided information about the Survey in a question and answer 

format. 

What is the ARB’s authority to conduct this Survey?

This request for information is made pursuant to sections 39600, 39607, 39665, 

39701, and 41511 of the California Health and Safety Code and section 91100, 

Title 17 of the California Code of Regulations. These sections authorize the ARB to 

require the submission of information needed by the ARB to estimate atmospheric 

emissions and carry out its other statutory responsibilities. 

Why is the Survey necessary?

The ARB maintains a statewide emissions inventory for all sources of air emissions 

such as cars, trucks, marine vessels, construction equipment, industrial facilities, and 

architectural coatings. The ARB’s emission inventory is regularly updated to reflect 

the most up-to-date emission information, including results of surveys such as this 

one.

The commercial harbor craft component in the emissions inventory has not been 

updated on a statewide basis for more than 10 years. It is necessary for us to gather 

information about the current in-use fleets in California. That way, we can reflect 

current fleet populations and provide a more accurate estimate of emissions in the 

emissions inventory for commercial harbor craft.

Who should complete the Survey form?

All owners/operators of commercial harbor craft that are operated in California are 

being asked to complete the Survey.

Do I have to complete the Survey?

Yes. State law requires that you provide the requested information by completing 

and returning the Survey. If the Survey does not apply to you, please state in the 

Survey why it does not apply to you and return it to the address indicated.

What information needs to be provided in the Survey?

The Survey requests specific information about each vessel. This includes 

information like who owns or operates the vessel, how the vessel is used, and where 

its home port is. The Survey also requests information on the propulsion and 
2002 Commercial Harbor Craft Survey

PART II: SURVEY OVERVIEW AND INSTRUCTIONS

D - 26

auxiliary engines on the vessel, including the make and model, the horsepower, and 

the engine’s age. Information on the typical operating parameters is also requested,

including the annual hours of operation, how far offshore the vessel is operated, and 

an estimate of annual fuel usage.

If the Survey information is claimed as confidential, how will it be treated?

The ARB has adopted regulations to protect the confidentiality of trade secrets 

(Title 17, CCR, sections 91000 to 91022). A summary of ARB's confidentiality 

regulations can be found in Part II of the Survey on the “Confidential Information 

Submittal Form.” You should fill out this form if you wish to designate any Survey 

information as confidential.

When do I need to return the Survey, and where do I send it?

Please return the Survey by February 14, 2003 to:

CONFIDENTIAL INFORMATION SUBMITTAL FORM

If you wish to designate any information contained in your survey data as CONFIDENTIAL 

INFORMATION, please provide the information requested below and return it with your 

completed Survey form.

In accordance with Title 17, California Code of Regulations (CCR), Sections 91000 to 

91022, and the California Public Records Act (Government Code Section 6250 et seq.), 

the information that a company provides to the Air Resources Board (ARB) may be 

released (1) to the public upon request, except trade secrets which are not emissions 

data or other information which is exempt from disclosure or the disclosure of which is 

prohibited by law, and 2) to the Federal Environmental Protection Agency, which 

protects trade secrets as provided in Section 114(c) of the Clean Air Act and 

amendments thereto (42 USC 7401 et seq.) and in federal regulation, and 3) to other 

public agencies provided that those agencies preserve the protections afforded 

information which is identified as a trade secret, or otherwise exempt from disclosure by 

law (Section 39660(e)).

Trade Secrets as defined in Government Code 6254.7 are not public records and therefore will 

not be released to the public. However, the California Public Records Act provides that air 

pollution emission data are always public records, even if the data comes within the definition of 

trade secrets. On the other hand, the information used to calculate information is trade secret.

If any company believes that any of the information it may provide is a trade secret or otherwise 

exempt from disclosure under any provision of law, it must identify the confidential 

information as such at the time of submission to the ARB and must provide the name, 

address, and telephone number of the individual to be consulted, if the ARB receives a 

request for disclosure or seeks to disclose the data claimed to be confidential. The ARB may 

ask the company to provide documentation of its claim of trade secret or exemption at a later 

date. Data identified as confidential will not be disclosed unless the ARB determines, in 

accordance with the above referenced regulations, that the data do not qualify for a legal 

exemption from disclosure. The regulations establish substantial safeguards before any such 

disclosure.

 confidentiality may be submitted to the state board prior to the time

 disclosure is sought. 

 (e) The state board shall, within ten (10) days of the date it sought to

 disclose the data or received the request for disclosure, or within 20 days

 of that date if the state board determines that there are unusual

 circumstances as defined in Government Code Section 6256.1, review

 the request, if any, and supporting documentation, if received within the

 time limits specified in subsection (b) above, including any extension

 granted, and determine whether the data is entitled to confidential

 treatment pursuant to Government Code Section 6254, 6255 or 6254.7

 or other applicable provisions of law and shall either: 

(1) decline to disclose the data and, if a request was received, provide to the

 person making the request and to the person claiming the data is

 confidential a justification for the determination pursuant to Government

 Code Section 6255; or 

(2) provide written notice to the person claiming the data is confidential and,

 if a request was received, to the person requesting the data that it has

 determined that the data is subject to disclosure, that it proposes to

 disclose the data, and that the data shall be released 21 days after

 receipt of the notice by the person claiming confidentiality, unless the

 state board is restrained from so doing by a court of competent

 jurisdiction. The state board shall release the data in accordance with

 the terms of the notice unless so restrained. 

 (f) Should judicial review be sought of a determination issued in accordance

 with subsection (e), either the person requesting data or the person

 claiming confidentiality, as appropriate, may be made a party to the

 litigation to justify the determination.
