RedactedNarrative: V1 was drifting in open water and V1's occupants were swimming and floating on life jackets directly behind V1 when they noticed a boat (V2) quickly approaching. V2 never veered or changed directions and continued to head straight at them. V2 struck V1 in the stern port side, while also striking the victim.  According to V2's operator and passenger, they were traveling across the lake attempting to take down a rain shield from across the front of V2.  V2 stated they believed they hit a stump at first but then realized they struck another boat. Both the operator and passenger of V2 stated they never saw V1 prior to striking them.
