We placed sixth out of thirteen in offshore B class in the 1992 Key West Worlds in a 30' Sonic. I put 13 pieces of tape on the dash that the owner thought represented laps. When we passed our first broken boat I pull a piece of tape off the dash. That's when he figured out I was counting competitors down not laps. We had a blast.
Great story. I've had to teach that lesson to my 16 YO and others.
