What effect will transferring fuel oil from No.1P double bottom to No.3P double bottom have on the trim of a vessel?

Correct Answer: Option D — The forward draft will decrease.

Transferring fuel from a forward tank (No. 1P) to an aft tank (No. 3P) shifts the longitudinal center of gravity aft. This movement increases the draft at the stern and decreases the draft at the bow. Consequently, the forward draft decreases as the vessel trims by the stern.
