RedactedNarrative: Vessel 2 was drifting in a southerly direction towards Browns Beach Marina. Vessel 2 had the engine off and all navigation lights illuminated. The bow of vessel 2 was pointing towards the Brown Beach marina which is in the southeast corner of the lake. Vessel 1 had departed their dock and went in a north west direction and traveled towards Snake Hill. Vessel 1 then turned to port and headed south east towards the browns Beach Marina. Two of the occupants of vessel 2 were standing on the swim platform and noticed vessel 1 coming straight at them. V1 continued its course and stated they did not see any lights on V2. V1 operator stated that there were so many lights on the shore and he couldn't distinguish the difference. As V1 closed in on V2 the operator then noticed V2 and quickly shifted his vessel into neutral and steered to the starboard side. The two persons standing on the swim platform jumped into the lake before the vessels collide. Both were retrieved from the water unharmed. The center pontoon on V1 struck the right side swim platform of V2 and the left pontoon struck the center of the swim platform. Both vessels drove in to the marina to seek assistance.
