I think it would depend on the distance of the race. Something too long may deter non-spin boats. The mere fact that it is a beach regatta, may deter a few teams that don't feel comfortable in the ocean. The past Cat Dashs would have 20-30 boats. I remember way back (late 80's- early 90's), there was a one day distance race in Atlantic Beach called Canonball Run. It would have 100+ boats. It was a race from Atlantic Beach to Cape Lookout and back. When we got to Cape Lookout, you would beach the boat inside the hook and run to touch the lighthouse. That would stop your time. They would have a keg and lunch waiting for about an hour break. They then restarted us for the trip back. It was a great race.
