RedactedNarrative: Vessel 2 was travelling southwest on Big Bearskin Lake.  Vessel 1, while pulling a tuber was travelling northwest.  Vessel 1 Operator stated that he was watching the tubers in the rear view mirror.  Vessel 1 struck Vessel 2 within its bow on the port side.  As vessel 1 was about to hit vessel 1, the operator accidently pushed the throttle forward instead of backwards which caused the bow of Vessel 1 to rise and rest on the port side of Vessel 2 damaging the rails, skirt and benches on that side of the boat.  It also caused 2 of the Vessel 2 passengers to be injured, one had a cut to his hand, the other a bruse on her wrist.
