🔍 Key Concepts

• Longitudinal Center of Gravity (LCG) – where the ship’s weight acts along the length • Longitudinal Center of Buoyancy (LCB) – where the buoyant force acts along the length • How the relative position of LCG and LCB affects trim (by the head or by the stern), versus list (athwartship)

💭 Think About

• If the vessel’s weight (LCG) is located aft of the buoyant force (LCB), which way does the ship tend to rotate longitudinally? Picture a seesaw: where is the weight relative to the pivot? • Which choices describe fore-and-aft trim, and which choice describes side-to-side inclination? Eliminate the ones that involve the wrong plane of movement. • If LCG and LCB are in the same longitudinal position, what trim condition exists? Now think about what happens when LCG moves aft of that point.

✅ Before You Answer

• Identify which options refer to trim (fore-and-aft: bow vs stern) and which refer to list (port vs starboard). • Confirm that LCG aft of LCB causes a rotational moment about the LCB – decide whether that makes the stern go deeper or shallower. • Verify your understanding that an even keel occurs when LCG and LCB are in longitudinal alignment, with no net trimming moment.
