During the final minutes leading into the start of Race 1 for the J Class at the Superyacht Challenge Antigua regatta a collision occurred between Svea and Topaz.
Both boats sustained damage and immediately retired from racing.
This was videoed from onboard Velsheda and was attributed to Nic Douglas and Bouwe Beking. Topaz (J8) is on starboard and Svea (JS1) comes in on port. Topaz evades but this swings her stern over and Svea climbs over it catapulting a crew into the water and snapping the back stay.
