🔍 Key Concepts

• GM (metacentric height) and what makes it positive or negative • Behavior of a vessel at an angle of loll • How BM (metacentric radius) and beam affect stability

💭 Think About

• Think about what physically changes when the vessel heels over to an angle of loll: is it KG, BM, or the underwater shape? • Which option describes something that would directly increase GM from negative to positive? Recall: GM = BM - KG (for G above keel). • Consider what happens to the waterplane and effective beam when a vessel is heeled instead of upright.

✅ Before You Answer

• Recall that GM = KB + BM - KG. Which term is most affected when the vessel heels to an angle of loll? • Ask yourself if KG actually changes just because the ship heels, without cargo or liquids moving vertically. • Visualize the waterplane shape at a heel angle: does the effective beam between port and starboard waterline intersections change in a way that affects BM?

KG is reduced as the vessel seeks the angle of loll

free surface effects are reduced due to pocketing

effective beam is increased causing BM to increase

underwater volume of the hull is increased
