CRAW has confirmed it is hosting the F18 nationals in Racine. At the last regatta, we had 3 F16 boats there and they asked if they should consider expanding it to include the F16 nationals. I have not been to Racine, but they have hosted 100+ boats there before. We said we'd check into it.
BTW I expect more F16 boats in CRAW next year. At least 2 people are considering them.
