Question 2189Deck Safety70% to pass
When a wind force causes a vessel to heel to a static angle, the _______________.
AI Explanation
The correct answer is B) the righting moment equals the wind-heeling moment.
When a vessel heels to a static angle due to wind force, the righting moment, which is the force that acts to restore the vessel to an upright position, must be equal to the wind-heeling moment, which is the force that causes the vessel to heel. This is a fundamental principle in vessel stability and ensures that the vessel remains in equilibrium at the static heel angle.
The other options are incorrect because: A) deck-edge immersion is a separate stability criterion, C) the centers of buoyancy and gravity are not necessarily in the same vertical line at the static heel angle, and D) the center of buoyancy does change as the vessel heels.
