H-1 — Recommended Practices and Standards Covering Visibility From the Helm Position

NOTES:

1. In order for this standard to be effective the boat must be operated in a reasonable and prudent manner.

2. Boats can be operated in a manner and at certain speeds causing trim and/or roll angles such that vision is obscured. This standard cannot assure that a boat can be operated without some loss of vision from the helm position while operating at high trim angles during the transition between displacement and planing mode.

3. This standard does not relieve the operator of the requirement to comply with the Rules of the Road.

These standards and recommended practices apply to boats 79 feet (24 meters) in length, or less, powered by machinery.

H-2 — Ventilation of Boats using Gasoline

NOTES:

1. The United States Coast Guard has promulgated mandatory requirements for ventilation in 33 CFR, Subpart K, Sections CFR 183.601 — CFR 183.630. Refer to the CFR for complete, current federal requirements.

2. Ventilation Principle — Ventilation cannot be relied upon to remove all flammable vapors emanating from the presence of liquid fuel resulting from fuel system failures or fuel spillage. See ABYC H-24, Gasoline Fuel Systems. Boat ventilation cannot create a safe condition when liquid gasoline is exposed to the atmosphere in a boat because liquid gasoline will continue to create gasoline vapors as long as liquid gasoline is present.

These standards and recommended practices apply to boats using gasoline for electrical generation, mechanical power, or propulsion, including outboard boats.

NOTES:

1. Ventilation guidelines for boats using diesel fuel are contained in ABYC H-32, Ventilation of Boats Using Diesel Fuel.

2. Ventilation cannot be relied upon to remove all carbon monoxide vapors that may be produced from the operation of the vessel or its equipment. See ABYC T-22, Educational Information About Carbon Monoxide, and TH-23, Design, Construction and Testing of Boats in Consideration of Carbon Monoxide, for further information.

3. Heat Dissipation — The ventilation system described in this standard is sufficient to provide for the requirements for ventilation of vapors from the engine space. However, the standard is not intended to provide for the ventilation required for heat dissipation.

S-30 — Outboard Engine and Related Equipment Weights

This industry conformity standard applies to all outboard boats less than 26 ft. in length.

NOTES:

1. This document is intended to serve as a single source for engine and related equipment weights to be used where applicable in ABYC standards and when referenced by other sources. This document will facilitate the adjustment of the weights reflected in the table as engine technology changes.

2. The weights contained in this document are higher than those listed in Title 33 CFR Part 183 and have been determined as a result of a review of existing outboard engine and related equipment weights. The weights reflected in the CFR are based on weights of engines manufactured in the 1970's. As engine technology has evolved weights have increased for the same given horsepower. Title 33 CFR Part 183 may eventually reference this document as the required weight table for engine weights used in flotation testing.

TH-22 — Educational Information About Carbon Monoxide

Carbon monoxide can accumulate in interior spaces and exterior areas. Carbon monoxide accumulation is affected by a multitude of variables (e.g., boat geometry, hatch, window and door openings, ventilation openings, proximity to other structures, swim platforms, canvas enclosures, location of exhaust outlets, vessel attitude, wind direction, boat speed, boat system maintenance, etc.)

This technical information report discusses many of these variables and enables the reader to better understand some of the more predictable effects. However, this report is limited in that it cannot cover all conceivable variables, and the reader is cautioned not to rely exclusively on it to prevent the accumulation of carbon monoxide.

The information in this technical information report concerns all boats.

TE-4 — Lightning Protection

The probability of a lightning strike varies with geographic location and the time of the year. When the conditions that create an electrical charge between clouds and the earth exist, there is nothing that can be done to prevent the lightning discharge. A boat can be struck in open water or while tied to the dock.

This technical information report applies to powerboats and sailboats if a lightning protection system is installed. Complete protection from equipment damage or personal injury is not implied.

A lightning protection system offers no protection when the oat is out of the water, and is not intended to afford protection if any part of the boat comes in contact with power lines while afloat or ashore.

Protection of persons and small craft from lightning is depended on a combination of design and maintenance of equipment. The basic guides contained in this technical information report should be considered and used in designing and installing a lightning protection system. However, in view of a wide variation in structural design of boats, and the unpredictable nature of lightning, specific recommendations cannot be made to cover all cases.
