V1 was traveling north in Blackwater Sound at a high rate of speed and hit a wake from another vessel.  The bow of V1 lifted and caught air.  This caused the bow of the vessel to go straight up in the air.  As the engine hit the water, the stern of the vessel was forced forward causing the vessel to flip backwards.  The bow then struck the water, breaking off just in front of the cockpit and landed upside down.  The operator was ejected at some point during this evolution.  His injuries were caused by impact with the vessel during ejection.  He was not wearing a PFD.; Operator received lacerations to the top of his head, upper lip, and left leg as he was being ejected from his vessel.  He also fractured two ribs on his left side.  He had slight edema from water in his lungs.
