Summary
A rescue-boat winch continued hoisting after its motor contactor fused because its duty rating was exceeded. Crew isolated power before the boat contacted the davit. The flash relays USCG recommendations to check contactor condition, compare duty ratings with recovery practices, verify safety-device design and train operators in power isolation.
