Trim is defined as the difference between which measurements?

• A. Difference between forward and aft draft
• B. Side-to-side tilt
• C. Cargo density
• D. Tank volume

Answer: (A)

Trim is the ship’s longitudinal tilt, defined by the difference between the forward draft and the aft draft. If the forward draft is deeper, the vessel trims by the bow; if the aft draft is deeper, it trims by the stern. This measurement comes from reading the water depth at the forward and aft perpendiculars and subtracting one from the other. Trim matters because it affects stability, hull stresses, loading balance, and safe maneuvering. The other ideas describe different concepts: side-to-side tilt is list, cargo density influences buoyancy but not how trim is defined, and tank volume is simply capacity.
