Man overboard — execute the Williamson Turn to return to the datum on a reciprocal track, then locate and recover the casualty before hypothermia reduces their survival probability to zero. Covers IAMSAR search-and-rescue patterns (expanding square, sector, parallel track sweeps), the Williamson and Anderson Turns for immediate MOB return, and SOLAS man-overboard equipment requirements including SART, lifebuoy with light, and smoke marker.
Man-overboard recovery is the most practiced emergency in maritime safety training and the most time-critical seamanship decision a watchkeeper faces. This game builds the course-and-timing discipline needed to execute a clean Williamson Turn in any sea state.
