What kind of boats are required to have a fire extinguisher onboard?

Boats with permanently installed fuel tanks are required to have a fire extinguisher onboard because the presence of fuel increases the risk of fire. These boats are often powered by gasoline, which is highly flammable. The regulations ensure that in the event of a fire due to fuel leaks or ignition, there is a means to suppress the flames and ensure the safety of those onboard. This requirement is critical for preventing potentially dangerous situations and protecting both the boat and its passengers.

While boats over a certain size, all sailing vessels, and boats with higher capacities may also have specific fire safety requirements, the most direct link to the need for a fire extinguisher lies with those equipped with fuel tanks, as the risk of fire is significantly escalated under those conditions.
