RedactedNarrative: At approximately 3:00 am, Vessel 1 was travelling across the lake using a spotlight to operate the vessel home.  Vessel 1 travelled past the island on Wheeler Lake and then hit something on the left side.  Vessel 1 Operator stated that he though they hit a rock as they did not see any other vessels on the lake.  It was foggy on the lake and Vessel 1 Operator went around and found the Vessel 2 which had been floating, not anchored and not under power.  Vessel 2 Operator stated that he had not had the green/red lights on, only his rear white stern light.
