🔍 Key Concepts

• Metacentric height (GM) and its effect on stability and rolling period • How weight shifts high vs. low affect GM • Relationship between larger GM vs. smaller GM and whether the vessel rolls faster or more slowly

💭 Think About

• Think about what happens to GM when you add weight high up on the vessel versus low down. Does that make the vessel more or less stiff? • Ask yourself: does a vessel with a large GM roll quickly or slowly? How about a vessel with a small GM? Which condition gives a longer (increased) rolling period? • For each choice, decide whether it tends to increase or decrease GM, then connect that to whether the rolling period becomes longer or shorter.

✅ Before You Answer

• For each option, decide clearly: does this increase GM, decrease GM, or leave it about the same? • Recall: a stiff vessel (large GM) has a short, quick roll; a tender vessel (small GM) has a long, slow roll. • Check which option(s) would decrease GM or increase the vessel’s tenderness, since that is tied to an increased natural rolling period.
