OUPV & 100-Ton Master · Stability
A vessel that rolls slowly and hangs at the end of each roll before returning is described as:
- AStiff, with excessive GM
- BIn a state of negative buoyancy
- CTrimmed by the head
- DTender, with reduced GM✓ Correct
Explanation
A tender vessel has a small GM: it rolls slowly and lingers at the extremes of the roll, which is uncomfortable but signals reduced reserve stability. A stiff vessel (large GM) snaps back quickly with a short, jerky roll.
