Cat 25 is a good boat, but I think it is a little too big to trailer regularly. It is fine if you are going to leave it in the water mostly, and only trailer it when you move to a new location. If you plan on keeping the boat on the trailer, and launching it each time you go sailing, then I would go with something smaller.
Also, what type of vehicle do you drive? With the 25, once you include weight of trailer and gear, you need something rater for at least 5000 pounds (preferably more).
