MARINE EXTINGUISHER REQUIREMENTS
Though not all motorboats are required to carry a fire extinguisher, it is highly recommended that all motorboats have some form of fire extinguisher aboard. Numerous types and sizes of fire extinguishers meet Coast Guard requirements. With any type of marine fire extinguisher, accessibility is of the utmost importance; ensure the fire extinguisher is mounted where it can be easily and quickly retrieved within arms reach of the operator or passengers in the event of a fire emergency.
