Deck General · Metacentric Height (GM)
A vessel has a very small but still positive GM. This vessel is best described as:
- AStiff, likely to snap-roll
- BTender, with a long slow rolling period and reduced comfort margin✓ Correct
- CNeutrally stable with zero righting moment
- DIn a state of loll
Explanation
A small positive GM means the righting moment is weak. The vessel rolls slowly (long period) and is called tender. Although technically stable, the small margin increases the risk of a dangerous list or capsize if additional weight is added high.
