upside down." In any event, adopting heaving to as a storm tactic proved to be a good preventive of capsize during the race. Not one of the hove to yachts were capsized or suffered any serious damage. See also Capsize of Drum (1985) and Capsize of Rambler (2011), both of which involved large Maxi yachts that lost their keels. In December 2008, the high speed experimental sailing hydrofoil trimaran Hydroptère set a world speed record, then pitchpoled while going over 60 knots. The turtled yacht had to be towed back to port for being turned right side up. In the 2011 Chicago Yacht Club Race to Mackinac, the high performance monohull sportsyacht WingNuts, a Kiwi 35, turtled in an extreme storm, killing the captain and one crew member. Later inquiry determined the boatspecifically its high performance extremely wide low displacement hullwas unfit for the location, weather, and the lengthy multiday race format, and urged race officials to change ratings and revoke privileges for similar boats to enter the race. The waves were not all that unusual, although the wind was. The boat may have buried one of its hiking wings into a wave, causing it to 'trip', and had the other lifted by the wind. It is rare but not unheard of for keelboats to turtle and remain upside down, particularly if its keel is intact. However, this boat's unique hull form, which made it very fast, also rendered it more stable upside down than right side up. This was a recipe for the disaster. This loss was occasioned despite a competent and experienced crew which was as well equipped and prepared as thought to be necessary. WingNuts met then current offshore stability standards, which failed to adequately take into account the dynamic effect of the "radical" winged hull. On 13 June 2012, in the trials leading to the America's Cup, Oracle Team USA on an AC45 spectacularly capsized the boat, and it was righted with minimal damage ("there's a little rip there") ten minutes later. Skipper Russell Coutts dismissed it as "a learning experience". This was an epilogue to earlier similar incidents by other teams in Australia. On 9 May 2013, the 2013 America's Cup challenger Artemis broke apart, broached, capsized, and turtled destroying its wing/sail and trapping two crew members under its hull. The AC72 wing-sail catamaran was sailed on behalf of the Royal Swedish Yacht Club, sponsoring
