The best fire extinguisher for a boat depends on several factors, including the type of fires you might encounter and compliance with US Coast Guard (USCG) regulations.

Let’s explore some Fire Extinguisher options:

Amerex B417T 2.5 Lbs. ABC Dry Chemical (5-B / Old B-I Compliant): This extinguisher is suitable for Class A, B, and C fires. It’s compact and effective, making it a popular choice for boats.

Ansul 436500 Sentry 10 lb ABC Fire Extinguisher (20-B / Old B-II Compliant): A reliable choice with a 10-pound capacity, meeting Class A, B, and C requirements.

Remember that the USCG has specific requirements for fire extinguishers on boats. Generally, having a tri-class (1A:10BC) fire extinguisher is recommended, and having more than the minimum required by the Coast Guard is always advisable. Ensure that your chosen extinguisher has a visible pressure gauge, an approved mounting bracket, and meets the necessary standards.
