Sailing under reefed jib and triple-reefed main, the Swan 44 Laughing Lady had its boom sheared cleanly just forward of the boom-vang attachment during an accidental jibe. The full force of 35 knots of wind whipped the sail over to leeward and snapped the boom in two. The mainsail was ripped to shreds.
Few cruising boats are built to be dropped vertically off huge waves. Sailing at seven knots, beam to the wind and waves, Break'nWind, a Hunter HC50, fell off an unusually large and steep wave, slamming into the trough far below. The impact of the free fall bent the boom vang, a two-inch stainless-steel tube with a stainless-steel ram inside, into a semicircle and crushed the ends of bulkheads and interior furniture.
