According to the USCG, all recreational boats with permanently installed fuel tanks, or spaces capable of trapping fumes, must have fire extinguishers readily available. This includes:
- Closed compartments under thwarts and seats where portable fuel tanks may be stored
- Double bottoms not sealed to the hull or not completely filled with flotation materials
- Closed living spaces
- Closed stowage compartments containing combustible or flammable materials
The number of extinguishers required depends on your vessel's length and whether a fixed suppression system is installed.
| Boat Length | No Fixed System Installed (# of 5-B extinguishers needed*) | Fixed System Installed (# of 5-B extinguishers needed) |
|---|---|---|
| Under 16 feet | 1 | 0 |
| 16 ft – under 26 ft | 1 | 0 |
| 26 ft – under 40 ft | 2 | 1 |
| 40 ft – under 65 ft | 3 | 2 |
