RedactedNarrative: Vessels 1 and 2 were operating on the Hudson River IAO of Tilcon. Both PWC operators denied having any recollection of the incident. They could not tell the the officer where the accident occurred, direction of travel or how they collided. V2 operator reported no injuries. V1 operator possibly has a broken nose/ laceration to his face and was admitted into the hospital. Neither operator possessed a Boater Safety Certificate. Based on the damage of the PWC's it would appear that this was a head on collision at a high speed. Inattention, inexperience and reckless operation appear to be contributing factors.
