RedactedNarrative: V1 was anchored at the south end of the Narrows with the occupants in the water swimming. V2 approached from the east heading west, negotiated a right hand turn to head north up the Narrows when it struck V1. V2 operator stated he had the bow up and the sun was in his eyes so he did not see V1.  V2's bow made contact with V1's stern traveling up onto V1's canopy.
