Just a thought stimulated by an earlier comment from last fall on this thread. I got to race with my buddy in a medium (for the Chesapeake) distance race last fall on his Hobie 20 which he had modified with wings. What a ride! An 18-20' beach cat with wings added is a sweet ride for us older gheezers: comfortable seating, no trapezing needed, and you miss 90% of the spray. In a wild spin run up the Choptank, we just sat on the back corner of the wing and let her fly.
If one's considering low cost racing without the comfort/flexibility issues of sailng on a trampoline, this could be a great re-fit to many older beach cats. Add a hard or soft pouch/cuddy and you have a pretty nice set up.
I admit it would not be easy to get this type of set up accepted for most of the distance racing on the bay. Thanks to the NASS for allowing beach cats in their Oxford race.
