RedactedNarrative: Unit 1 was travelling NE when he crossed over the wake of another vessel that was also travelling NE.  When Unit 1 crossed the wake, it pulled the tiller handle of the motor from his hand.  At this point Unit 1 made a hard and abrupt turn that ejected all three people on board into the water.  Operator was wearing his lanyard which did disconnect.  The propeller did strike the person who was riding in the middle section of the vessel once he was ejected into the water.
