A classic T-bone collision severely damaged the boat sometimes raced by the King of Spain as triple gold and silver Olympic medallist Jochen Schuemann misjudged an attempt to take avoiding action in the Audi MedCup regatta on Sardinia's Bay of Angels.
The 56-year old Schuemann was at the helm of the Franco-German boat All4One and had no right of way as he tried to dip behind Bribon, owned by the king's friend Jose Cusi and on which British Olympic medallist, America's Cup skipper and Volvo race skipper Ian Walker is tactician.
The king was not on board and no-one was injured but Bribon cannot continue racing and repairing the damage could cost as much as €100,000. It may not even be ready for the class world championship which starts in Valencia on 4 October.
The only damage to All4One was a crumpled bowsprit. The team was fitting a spare overnight and hoped to be able to race again on Thursday, which sees a single coastal race which scores points and a half. That should leave a pair of two-race days on Friday and Saturday.
Conditions were tricky for the second day's trio of races and it was again a mixed bag of a day for Britain's Team Origin starting with an eighth, followed by a fourth and ending with a second
But the mixed fortunes applied to all, though Emirates Team New Zealand, with a last-placed 10th, a second and a third, is now looking unstoppable in its quest to defend successfully the series championship it won so impressively last year.
The Kiwis have a 50-point margin over their nearest rivals, the Quantum team from America. Origin is comfortably in fourth place behind the Argentinian boat, Matador.
