Question 2658 Deck General

The correct answer is B) vessel gross tonnage. The number of fire extinguishers required on an uninspected "motor vessel" is based on the vessel's gross tonnage, as per the regulations outlined in 46 CFR 25.30-10. This regulation specifies the minimum number of fire extinguishers required based on the vessel's gross tonnage, with more extinguishers required as the gross tonnage increases. The other answer choices, such as vessel length (A), number of crew members (C), or vessel draft (D), are not the determining factors for the number of fire extinguishers required on an uninspected motor vessel. The gross tonnage of the vessel is the key factor that dictates the fire extinguisher requirements.
