The Royal Western Yacht Club in Plymouth, southwest England, says three boats set off emergency beacons Friday amid 60-knot (69 mph, 111 kph) winds and 50-foot (15-meter) waves.
Canada's coast guard sent ships and air support to the boats. Cruise line Cunard said the Queen Mary rescued a lone yachtsman as part of the operation.
The ship's captain, Chris Wells, said Saturday the yachtsman "is safe and well."
The yacht club said everyone aboard three damaged boats was rescued and no injuries were reported. Two other boats were also damaged.
The boats were taking part in a race from Plymouth to Newport, Rhode Island.
