Question 1755 Deck Safety
70% to passA vessel aground may have negative GM since the _______________.
A
displacement lost acts at the point where the ship is aground
B
lost buoyancy method is used to calculate KM, and KB is reduced
C
decrease in KM is equal to the loss of draft
D
virtual rise of G is directly proportional to the remaining draft
AI Explanation
The correct answer is A) the displacement lost acts at the point where the ship is aground. When a vessel runs aground, the displacement lost acts at the point where the ship is in contact with the ground. This causes the center of gravity (G) to shift upwards, resulting in a negative GM (metacentric height). The other answer choices do not accurately explain the reason for the negative GM in a grounded vessel.
