RedactedNarrative: V1 was occupied by 3 individuals who decided to go bow fishing out of the 16' flat bottom Polar Kraft with a homemade wooden platform installed on the front of the boat. After leaving the Lincoln access boat ramp at Saylorville Lake on the evening of November 7th, 2014, V1 navigated north up to the Mosquito Creek area.  After bow fishing for 15 minutes they decided to return back to the ramp. On the way back to the boat ramp the waves continued to get bigger as the wind was picking up.  Wind speeds that night reached 25+ mph. The waves started going over the side of the boat and the boat sank fast once it started filling up with water.  Operator and occupant1 were the first ones to jump out of the boat and lost contact with each other & lost contact with the victim.  Both survivors swam to shore but victim didn't make it.
