Timbo, sounds like your dad lives near lake texhoma. Its a massive lake something like 90k acres of water. It's a bit crazy when the rednecks get to drinking. Other than that is a good lake and well within driving distance to me
Well my Dad doesn't have a cat, just a ski boat, and I'm in centeral Florida. Like Terry Back said above, you should take a flight to Orlando around time for the Wildcat Regatta, (Oct. 2-3) and get a ride on an F16, there will be many to look at of all variety, and some F18's and A cats as well as the Hobies.
There is very little correlation to a keel boat vs. the light cats, about the only thing that is the same is you still use the wind in the same way, the results however are very different and the little cats react to every puff, Very Quickly vs. a keel boat.
It's a fun challenge and you should take a ride if you can find one.
