Fire Extinguishers
Coast Guard approved fire extinguishers are required on certain boats.  Extinguishers are classified by letter and a number symbol.  The letter indicates the type of fire the unit is designed to extinguish (Type B for example is designed to extinguish flammable liquids, such as gasoline, oil, and grease fires).  The number indicates the relative size of the extinguisher (minimum extinguishing weight).  Coast Guard approved extinguishers are hand portable and have specific marine type mounting brackets.
Boats required to carry fire extinguishers: All motorboats with inboard engines All motorboats 26 feet or more with outboard motors All boats with closed compartments and compartments under seats where portable fuel tanks can be stored All boats with double bottoms not sealed to the hull or which are not completely filled with flotation materials All boats with closed living space All boats with closed stowage compartments in which combustible or flammable materials are stored All boats with permanently installed fuel tanks.  Fuel tanks secured so they cannot be moved in case of fire or other emergency are considered permanently installed.
