🔍 Key Concepts

• Transverse center of gravity (TCG) and its relation to vessel stability • Difference between heel, list, trim, and loll • How a vessel behaves when weight is off-center versus when stability is marginal

💭 Think About

• Think about whether the condition described (TCG off the longitudinal centerline) is temporary/caused by an external force, or a more or less steady condition due to weight distribution. • Ask yourself which terms apply to angles of inclination about the longitudinal axis (side to side) versus the transverse axis (bow to stern). • Consider which term is used when a vessel takes up an angle because of a permanent off-center weight, with no external moment acting.

✅ Before You Answer

• Verify which motions/conditions (heel, list, trim, loll) are associated with the ship’s longitudinal axis versus transverse axis. • Confirm which term describes a more or less steady inclination caused by weight distribution, not by wind or turning forces. • Check that your chosen term correctly matches a MODU’s side-to-side inclination due to its TCG being off the centerline.
