70% to passThe factor contributing to the greatest effect on the ship's period of roll is the _______________.
Amoment to trim 1 inch (MT1
BB
CC
DD
AI Explanation
The correct answer is A) moment to trim 1 inch (MT1). The period of roll of a ship is primarily affected by the ship's metacentric height (GM), which is the distance between the center of gravity (G) and the metacenter (M). The moment to trim 1 inch (MT1) is a measure of a ship's stability and directly influences the GM, and therefore the period of roll. A higher MT1 value indicates greater stability and will result in a shorter period of roll. The other options (B, C, and D) do not have a direct impact on the ship's period of roll.
