Choosing the Right Boat Fire Extinguisher
Having a properly rated marine fire extinguisher onboard isn't optional - it's a vital pat of safe boating. The U.S. Cost Guard (USCG) required all powerboats to carry at least one approved extinguisher, and the size and number you need depend on your vessel's length and engine configuration.
Most boats use Type B-I or B-II fire extinguishers, which are rated for flammable liquids like fuel and oil. For smaller boats under 26 feet, a single B-I extinguisher is usually sufficient. Larger or enclosed vessels may need multiple extinguishers placed in accessible areas near engines, cabins, and fuel tanks. For added safety, pair your extinguisher with a marine vapor or high-water alarm to detect hazards early and prevent fires before they start.
