Greg Duff, a Newport Beach resident, was participating in the final day of the Sprint Nationals Boat Races at Marine Stadium on Aug. 5 when the crash happened, according to race director Ross Wallach.

He and other racers were headed into a turn at more than 100 MPH when another boat collided with his, Wallach told the Post. He was hospitalized in critical condition in the intensive-care unit where doctors performed multiple operations in an attempt to save him, according to Wallach.

Greg Duff’s friends and family have set up a fundraiser to collect donations for his hospital bills.
