Deck General · Stability Definitions
The mean draft of a vessel is 18 feet forward and 22 feet aft. What is the trim, and in which direction?
- A4 feet trimmed by the head
- B4 feet trimmed by the stern✓ Correct
- C2 feet trimmed by the stern
- D40 feet trimmed by the stern
Explanation
Trim = aft draft minus forward draft = 22 - 18 = 4 feet. Because the aft draft is greater, the vessel is trimmed by the stern. Trim by the head means the forward draft exceeds the aft draft.
