One Type I, II, III or V Coast Guard-approved wearable life jacket must be carried for each person aboard. Life jackets must be readily accessible and properly fit the intended wearer.
Note: An inflatable life jacket must be worn to be considered readily accessible. In addition, the vessel must carry an approved Type IV throw able device, which should be immediately available.

Fire Extinguisher:
Three B-I or one B-I and one Coast Guard-approved fire extinguisher must be carried when no fixed fire extinguishing system is installed in machinery spaces. With a fixed system in the machinery space, two Type B-I or one Type B-II extinguisher must be carried.

Backfire Flame Arrestor:
A Coast Guard-approved backfire flame arrestor is required for inboard gasoline motors that are not exposed to the atmosphere above the gunwale level.

Muffling System:
An effective muffling system is required for the exhaust of each internal combustion engine. Unmodified outboards usually meet legal requirements (see page 37).

Ventilation System:
All motorboats or motor vessels, except open boats made after 1940 and using gasoline as a fuel must have at least two ventilator ducts fitted with cowls or their equivalent for the efficient removal of explosive or flammable gases from all engine and fuel tank compartment bilges

Boats built after July 31, 1990, that have a gasoline engine for electrical generation, mechanical power or propulsion must be equipped with an operable ventilation system.

Sound Signaling Devices:
Vessels 39 feet 4 inches (12 meters) or more in length are required to carry a whistle and a bell.

Visual Distress Signals (Coastal Waters Only):
All boats 16 feet or more in length must carry devices aboard at all times. Boaters must carry either of the following devices that are suitable for day or night use:

  • Hand red Flare, distress signals

  • Pistol projected parachute red flare distress signals
  • Hand-held rocket-propelled parachute red
  • Hand-held orange smoke distress signals (day only)
  • Distress signal for boats, red aerial pyrotechnic flare
  • Orange flag (day)
  • Electric distress light for boat (night)


Navigation Lights:
Navigation lights must be kept in serviceable condition and displayed between sunset and sunrise and at times of restricted visibility. A recreational motor-powered Bessel underway is required to display a masthead light forward, red and green sidelights and a stern light.
