Deck General · Centers (G, B, M, K)
The center of gravity (G) moves when:
- AThe vessel heels to either side
- BA weight already on board is shifted✓ Correct
- CThe vessel pitches in a seaway
- DWatertight compartments are opened to the sea
Explanation
G shifts only when weight is added, removed, or moved. Heeling or pitching changes the position of B but not G, because the distribution of mass aboard does not change with heel angle alone.
