I have an FXone and love it. I'm a twig, but it handles bigger guys quite well. My boat is an 04', but the serial number say's its an 05' and I paid a little over 10k for mine.

Spinnaker sailing is so fun. I'm just learning at it but flying a hull both ways on the course is a phenomenal experience.

At 250lbs I don't think you can race it. I think the maximum weight you can add is 30lbs to make minimum, but it may be 50lbs. Short of the Queen Mary you should be able to right just about anything.
