🛟 Self-Righting Lifeboat Stability Curve and Capsize Recovery Lab

A generic 12 m self-righting rescue lifeboat with a sealed wheelhouse: the righting arm GZ curve is integrated numerically from the hull geometry, with metacentric height, capsize energy as the area under GZ, stability of the inverted state and nonlinear roll in beam seas. An experiment compares the roll rate that capsizes the boat with the energy balance.
