Deck General · Angle of Loll
What condition most commonly leads to a vessel developing an angle of loll?
- ALoading too much ballast in the double bottom
- BConsuming fuel and water from low tanks during a voyage, raising G✓ Correct
- COverloading the vessel beyond its summer load line
- DFree communication with the sea through an open sea chest
Explanation
As a voyage progresses, fuel and fresh water are consumed from low tanks. This removes weight from below G, causing G to rise. If G rises above M, GM becomes negative and the vessel develops a loll. This is why stability must be monitored throughout a voyage, not just at departure.
