Question 60Deck General70% to pass
You are preparing for what promises to be a rough ocean passage. Your 120-foot schooner carries a yard on the foremast, about 50 feet above the water. The yard weighs about 1000 pounds. If you take the yard down and stow it on deck for the trip, you will _______________.
AI Explanation
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.
