RedactedNarrative: After interviewing all four subjects involved, and inspecting the damage to both vessels, this is a summary of what occurred.  Vessel 1, a 48’ Sabre Yacht owned by operator, was cruising north in the ICW of Roberts Bay at a speed of approximately 18 mph; there was only one other occupant aboard this vessel.  The owner and operator of Vessel 2, a 29’ Tidewater, was overtaking V1 while traveling north in the ICW of Roberts Bay; There was only one other occupant of V2. 
  
  	According to the V2 subjects, while attempting to overtake along V1’s portside, the bow of their vessel was thrown to the right (back towards the transom of V1) while traversing through V1’s large wake.  This caused Operator2 to accelerate the throttle controls and lose his footing, falling to the deck.  Operator2 recalled being less than 50’ away from V1 at this time.  In the mere second or two before impacting the transom of V1, Operator2 regained his footing and may have steered starboard at the time of impact.  
  
  	Vessel 2 struck V1 with enough speed and momentum that the lower bow of V2 launched up the swim platform (which extended off the transom of V1), causing the upper bow and anchor to impact the top portion of V1’s transom.  The momentum continued V2’s launch over the transom and into the roof section of V1.  Ultimately, V2 launched over the starboard transom, coming completely out of the water, and clearing the starboard side of V1 before landing back in the water upright.  At that point in time, Operator2 was able to pull back the throttle and retake control of his vessel. 
  
  	From subject’s perspective within the cabin of V1, he described V2 as always coming closer at a high rate of speed.  Subject did not recall V2 ever changing course as if to go around, at the last second, he warned to operator1 of the impending collision, and they both dove to the floor for shelter.
