Q

What is used as an indicator of initial stability?

🔍 Key Concepts

• Initial stability vs. overall (large-angle) stability • Meaning of the terms GM, GZ, KM, and KG on a stability diagram • How the metacenter (M) and center of gravity (G) relate when a vessel is heeled slightly

💭 Think About

• Ask yourself: which quantity directly describes how ‘stiff’ or ‘tender’ a ship feels for small angles of heel? • Think about which term is a righting arm and which term is a metacentric height • Consider which of these values changes with loading (weight distribution) and which is used as the classic quick measure of initial stability in ship design

✅ Before You Answer

• Be clear which symbol represents metacentric height and which represents righting lever • Recall that initial stability is concerned with very small angles of heel (first few degrees) • Verify in your notes which parameter is traditionally used as the quick numerical indicator of a vessel’s initial stability (how stiff or tender it is)
