The term for the difference between forward and aft drafts is called what?

• A. List
• B. Heel
• C. Draft
• D. Trim

Answer: (D)

Fore-and-aft attitude describes how the ship sits along its length, specifically the difference in depth between the bow and the stern. The term for that difference between forward and aft drafts is trim. It tells you whether the bow or stern sits lower in the water and by how much. Trim is adjusted with ballast, cargo distribution, or lifting operations to optimize stability, propulsion efficiency, and sea-keeping. The other terms describe different tilts: list is side-to-side tipping, heel is a tilt about the same axis caused by forces, and draft is the depth at a given point, not the difference between two points.
