I was there racing on an I-20 and I agree that it was silly to only award class trophies when the individual classes only had 2 or 3 boats each. Results were posted as overall, but trophies were not awarded as such. Overall it worked out to:

Ding F-18
Langefeld I-20
Bedgood I-20

Not too sure what happened after that, but I think it was Pete (F-16), then T-Back (F-16).
