Contact the HCA and ask if they want them to use for trophies. If they have any creative instincts, they will. So tell them you can stuff them into some boxes and find out what the UPS ground shipping charges will be. They send you the shipping money, and you ship them to HCA (or whoever the regatta organizers are).

I'm picturing the two pointy ends being for 1st and 2nd place and the two transom ends being for last and second to last, and the others for 3rd through whatever.

My ideas about trophies are sometimes a bit weird, but I think that if I were a Hobie 14 sailor, it would be neat to win a piece of an ancient Hobie 14 as memorabilia, since they don't make them any more.
