A nineteen year old sailor in a Zap Cat struck a submerged object and was thrown from his boat whilst travelling at approximately forty five knots. The impact with the water caused him to black out temporarily, tore off his lifejacket and injured his neck and leg muscles. The circling boat was observed by the volunteers at the National Coastwatch lookout at Froward Point who pinpointed the casualty some one hundred metres from his boat and alerted the Coast Guard. The Coast Guard called out the ILB and also called all vessels in the Dartmouth area. The Fishing boat Deborah Jane responded and had just picked up the casualty as the ILB arrived. A crewman from the ILB was placed on the Catamaran and she and the casualty were brought back to port. The casualty was transferred to Dartmouth Hospital.
