RedactedNarrative: The Operator of Vessel 1 was paddling from Middle Bass Island to Marblehead Lighthouse.  As it began to get dark, the Operator of Vessel 1 was approximately 1 mile north of the Marblehead Lighthouse.  At this point, with darkness approaching, the Operator began paddling aggressively to get to shore; the Operator could not keep Vessel 1 perpendicular to the waves and Vessel 1 subsequently capsized.  The Operator of Vessel 1 then tried to re-board Vessel 1, but was initially unsuccessful; the Operator was later able to re-board, but the cockpit of Vessel 1 was full of water and partially submerged at this time.  The Operator then tried to swim Vessel 1 to shore, but was also unsuccessful.  After spending the night out, the Operator tried on the following morning to swim to Cedar Point, but was also unsuccessful.  At approximately 4:00 p.m. on that same day, the Operator was observed by another boater in the area, pulled from the water, and brought to shore.
