With your weight, you may want to consider a H20. There should be several newer ones on the market at a good price, since the racing class has been dwindling due to the emergence of the F18 class. I sold my 2000 model H20 last year well below what I would have liked to gotten. The H20 is fast fun boat that is forgiven with the added weight. You can take plenty of people on it to. Just be sure to inspect a used H20 for cracks at the lip of the hull and under the crossbars. The manufacture went through a period where they were not putting enough fiberglass in some major stress points... If you want a more durable boat, but not as fast, go with a TheMightyHobie18. They are tanks. Nacra 5.8 or 6.0's are also good choices.
