I'd venture to say - overscheduling.

You had the Statue Race, then Rock Hall JO event (that drew a lot of Hobie parents), then the Barnegat Breezer regatta, then the Corsica River event last weekend.

Area C is pretty much Hobie 16 and 17 territory - they're not so much interested about winning a spot to compete in an event on a spin boat that's totally different than what they're used to sailing.
