Question 1899 Deck General

The correct answer is B) the number of persons on board at the time. The small passenger vessel regulations require that the number of approved adult life jackets carried must be equal to the number of persons on board at the time. This ensures that there are enough life jackets available for all passengers and crew in case of an emergency, regardless of the vessel's maximum capacity listed on the Certificate of Inspection. The other options are incorrect because they do not accurately reflect the regulatory requirement. Option A is based on a percentage of the maximum capacity, which may not match the actual number of people on board. Options C and D also use percentages, which are not the correct standard for this regulation.
