Vessels "A" and "B" are identical; however, "A" is more tender than "B". This means that "A" relative to "B" has a __________.

Correct Answer: Option A — smaller GM

A tender vessel is defined by a small metacentric height (GM). Because GM is the distance between the center of gravity and the metacenter, a smaller GM results in a slower rolling period and less initial stability compared to a 'stiff' vessel, which has a larger GM.
