Question 2154 Deck Safety

The correct answer is B) for small angles of inclination. Metacentric height (GM) is a measure of a vessel's initial stability, which is the ability of the vessel to resist overturning for small angles of heel or inclination. Metacentric height is an indication of a vessel's stability for small angles of inclination because it represents the distance between the center of gravity and the metacenter, which is the point around which the vessel initially rotates when a small heel or list occurs. The other answer choices are incorrect because: A) Metacentric height is not an indication of a vessel's stability for large angles of inclination, as other stability criteria become more important at larger angles. C) Metacentric height is relevant for indicating a vessel's stability, not for "no case." D) Metacentric height is specifically an indicator of stability for small angles of inclination, not for all angles of inclination.
