V1 was on plane at approximately 20-25 knots (est.).  V1 encountered prop wash from a working tugboat and lost directional control.  Operator of V1 reduced throttle, which also reduced steering effectiveness, causing V1 to turn to port .  V2 went full ahead to avoid collision in an attempt to allow V1 to pass astern.  Operator V1 turned back to starboard to avoid collision.  Port side of V1 struck port side of V2.
