Question 620 Deck Safety
70% to passYour stability calculations indicate your vessel has a marginal GM. Which of the following is the most effective way to increase the stability of the vessel?
A
lower the center of buoyancy and raise the center of gravity
B
raise the center of buoyancy and reduce freeboard
C
raise the center of gravity and raise the center of buoyancy
D
lower the center of gravity and raise reserve buoyancy
AI Explanation
The correct answer is D) lower the center of gravity and raise reserve buoyancy. Lowering the center of gravity and increasing the reserve buoyancy are the most effective ways to improve the stability of a vessel with a marginal GM (Metacentric Height). Lowering the center of gravity increases the righting moment, which helps the vessel resist heeling. Raising the reserve buoyancy, or freeboard, increases the vessel's ability to resist capsizing in rough seas. The other options either do not directly improve stability or could potentially decrease stability.
