Question 60 Deck General

The correct answer is B) increase your vessel's GM. Lowering the yard from the foremast will decrease the vessel's vertical center of gravity (VCG), which in turn will increase the metacentric height (GM) of the vessel. A higher GM means the vessel will have a greater righting moment, resulting in a more stable and less "tender" (less roll-prone) motion in rough seas. The other options are incorrect because: A) Decreasing the VCG by lowering the yard will actually increase the metacentric height, not decrease it. C) Lowering the yard does not directly affect the vessel's reserve buoyancy. D) Increasing the GM will give the vessel a gentler roll, not a more pronounced one.
