Vessel 3 was docked and not in motion at the time of the incident.  The Operator of Vessel 1 reported that they were just leaving the area and were just starting to bring Vessel 1 up onto plane (approximately 10 miles per hour) when an Occupant aboard Vessel 1 saw Vessel 2 approaching from their stern at a high rate of speed.  The Operator of Vessel 1 then turned hard to port to try to avoid a collision at which time Vessel 2 struck the starboard stern of Vessel 1.  The impact of the collision forced Vessel 2 into a sharp turn to starboard and Vessel 2 came to rest after striking an adjacent dock and Vessel 3. All v1 occupants suffered injury from impacting the vessel.
