As an engineer, you should be familiar with the conditions that will cause a vessel to transversely incline, list, or trim. Which of the following conditions causes a vessel to trim?

Correct Answer: Option B — Fore and aft shift of G.

Trim is the longitudinal inclination of a vessel. A fore and aft shift of the center of gravity (G) changes the longitudinal righting moment, causing the vessel to rotate about the center of flotation, thereby altering the forward and after drafts relative to one another.
