I think that's a great idea. But should it include all areas you can put your cat in and sail from (such as a boat ramp) or only areas such as beaches you are allowed to sail from? Last weekend I was up at a state park that is on the beach in Hollywood. A beautiful beach. The park ranger told me that if I could get the catamaran to the beach through the walking paths without driving it with the car then I was welcome to do so. I am constantly looking for nice places to sail from. If everyone puts in their .02 I'm sure we can get a much more complete database than the on the wire one.
