Question 1747 Deck Safety

The correct answer is B) longitudinal stability. The tendency of a vessel to return to its original trim after being inclined by an external force is a measure of the vessel's longitudinal stability. Longitudinal stability refers to a vessel's ability to resist changes in its longitudinal trim, which is the difference in draft between the forward and aft ends of the vessel. The other options are incorrect: A) Buoyancy is the upward force exerted by a fluid on a submerged object, which is not directly related to the vessel's tendency to return to its original trim. C) Transverse stability refers to a vessel's ability to resist rolling or heeling, which is a different aspect of stability. D) Equilibrium is a state of balance, not a measure of the vessel's tendency to return to its original trim.
