🔍 Key Concepts

• TCG (Transverse Center of Gravity) vs LCG (Longitudinal Center of Gravity) – what direction does each one measure? • What does it mean physically when a vessel is level with no environmental forces (no list, no trim)? • Relationship between symmetry about the centerline and the transverse position of the center of gravity.

💭 Think About

• Ask yourself: does the word "forward" describe a transverse (side‑to‑side) position or a longitudinal (fore‑and‑aft) position? Which center of gravity uses that direction? • If a vessel is floating upright with no list, where must the center of gravity lie in relation to the centerline? • Look at the units and descriptions in the answers: which one is actually describing a transverse location, and which ones are describing a longitudinal location? Make sure you match the right type of center of gravity to the right direction.

✅ Before You Answer

• Be sure you know that TCG is measured port/starboard from the centerline, not fore and aft. • Confirm that "forward of amidships" refers to a longitudinal distance, which is associated with LCG, not TCG. • Before choosing, ask: if TCG were not on the centerline, what observable condition (like list or heel) would you expect, given that the problem says the vessel is level?
