For a vessel in the 26 to 40 feet range with no fixed fire suppression system, what is the required extinguisher configuration?

• A. Two B-I or one B-II
• B. One B-I and One B-II
• C. Three B-I
• D. One B-I only

Answer: (A)

On boats in the 26–40 ft range without a fixed fire suppression system, you must carry two portable extinguishers for Class B fires (flammable liquids). The allowed configurations are either two B-I extinguishers or one B-II extinguisher. A B-II has a higher overall capacity and is considered equivalent to having two B-I extinguishers, which is why either setup meets the requirement. This ensures there's enough portable extinguishing power and a backup in case one unit is used or not readily reachable, addressing the practical risk of fuel fires on a mid-sized vessel.
