Vessel 1 was attempting to return to shore with the approach of an incoming storm.  The Operator of Vessel 1 was turning Vessel 1 into the incoming waves when one of the waves struck the starboard side of Vessel 1 and half filled Vessel 1 with water, stalling the motor on Vessel 1. Several additional incoming waves completely swamped Vessel 1, and then capsized Vessel 1 sending the Operator into the water.   The Operator was able to climb onto the top of Vessel 1 after the capsizing and the Operator was located and rescued in that location on the following morning.
