RedactedNarrative: Boat with four occupants was headed NE on the lake en route to a family cabin on Sand Point Lake. The operator reported his spotlight flickered then went out and he lost sight of a buoy marker. As the operator started to throttle down, the boat hit large visible and submerged rocks on the south side of Indian Island. The boat possibly went airborne for a short distance and landed on submerged rocks in shallow water. Two female passengers were in the cabin area, and one sustained injury and was taken to the hospital. The operator and a male passenger received minor injury. The operator refused medical treatment. The male passenger was taken to the hospital but refused medical attention once he was there. Life jackets were on board, but were not being worn at the time of the incident. The boat received damage. Alcohol was not a factor.
