Show the answer
Correct answer: d) GM decreases and the boat loses stability.
Why it is correct
Moving a weight vertically raises G without shifting it sideways. So there is no heel, but GM decreases and stability is lost.
Why the others are not
- a) Buoyancy does not move, since the submerged volume is unchanged.
- b) A vertical shift causes no heel.
- c) G rises.
How to work it out in the exam
- Vertical: GM changes. Sideways: heel.
