🔍 Key Concepts

• Use the rolling period / metacentric height (GM) formula that relates vessel beam, rolling period, and GM. • Be careful converting feet and inches into a single unit before using the formula. • Remember that the rolling-period formula often uses seconds and feet, and may include a constant (like 0.44 or similar) depending on units.

💭 Think About

• What standard formula connects a ship’s natural rolling period (T), beam (B), and GM? Write it down first. • Once you rearrange that formula to solve for GM, what values for T and B will you plug in, and how will you handle the beam and draft in the problem? • After computing GM, which answer choice is closest to your computed value (watching for rounding)?

✅ Before You Answer

• Confirm you’ve converted 7'-10" correctly if you need draft in decimal feet. • Confirm you are using beam in feet and period in seconds consistently in the rolling-period formula. • Double-check your squaring operations (e.g., (T^2) or (B^2)) and make sure you don’t mix up numerator and denominator when solving for GM.
