Mystic man water taxi from Jalousie to Anse Chastanet hotel. Waited 45 mins fror recalcitrant Americans. Good briefing using Marine Park Artboard. Off from hotel beach then bouyancy check at 3m. Superb reef, with very strong current running beyond the western point. Very hard finning against it. (Why?) Small cave with turnaround but no interesting marine life inside. Mark went back to find two missing Americans, but they had already aborted the dive and beached.
