I have very limited experience with the Gemini but the thing that I have noticed being on one is that they a re terribly noisy in any sort of waves. That puts them off my list of possibles.
One of our customers just dropped off the lit. on the Tom Cat for me to look at and make a recommendation but I have not looked at it much. The one thing I don't like is the centerboard that is surface pierceing by itself( not in a hull). I would think that it would collect weeds alot and be very subject to ventilation. Dave
