PWC Insurance, Safety Equipment for Class A Recreational Vessels More on Fire Extinguisher
One USCG-approved B-1 type fire extinguisher is required for all recreational motorboats except outboard-powered motorboats less than 26 feet long if constructed in a manner that will not allow gas fumes to accumulate. If your boat has a built-in fuel tank, an inboard engine, compartments where portable fuel tanks may be stored, or open areas between the hull and deck where flammable or explosive gases could accumulate, you must carry a fire extinguisher. Non-motorized boats are exempt from the fire extinguisher requirements.
NOTE: When an approved fixed fire extinguishing system is installed in the machinery space(s), it may be counted in the place of one B-I type hand-held portable fire extinguisher. Some fire extinguishers require specific mounting brackets for approval. Read the label on your fire extinguisher for this information.
