Small wooden hull passenger vessels, whose routes are limited to coastwise warm water routes on the high seas, must carry approved life floats or buoyant apparatus __________.

Correct Answer: Option B — for not less than 100% of all persons permitted on board

For small wooden passenger vessels on coastwise warm water routes, regulations require life floats or buoyant apparatus for at least 100% of all persons permitted on board. This ensures that even in less severe water temperatures, every passenger has access to primary lifesaving equipment during an emergency.
