I took this in Pt. Pleasant, NJ. I was young, I think the race was still the Hennesy Grand Prix or maybe just became the Benihana. I didn't recall seeing the boat in the race that day.
Yes, It was called SEA KNIFE - We filmed it after the completion of a race - It was unique - kinda wet ride too -. It would slow down in a hurry as well when it dove into a big wave. Message T3x and ask him - he should have film of it -
