Two crew were thrown overboard and seriously injured in a top-speed collision between J Class superyachts jockeying for position on the start line of the Antigua Superyacht Challenge.
Both Svea and Topaz retired immediately with severe damage.
The 140ft, 180 tonne yacht smash was filmed by a guest aboard another competitor. The video went viral.
Louise Morton, Class Secretary, said: ‘As a class we remain thankful that the injuries to crews were not more serious or more widespread. We have fully reviewed what happened and lessons for the future have been learned in every different area.’
Morton refused to comment on what those lessons were when Ocean Sailor contacted her. One crew suffered several broken ribs.
