OUPV & 100-Ton Master · Stability
A vessel that is 'tender' (low GM) will:
- ARoll quickly with a short, snappy period
- BRoll slowly with a long, easy period and recover sluggishly✓ Correct
- CNot roll at all
- DAlways capsize in calm water
Explanation
A tender vessel (small GM, high G) has a long, slow roll period and recovers sluggishly, hanging at the end of a roll. A stiff vessel (large GM) snaps back quickly with a short, jerky period. Both extremes are undesirable; the goal is a moderate, comfortable period.
