Buy a Hobie tramp. They are worth every penny (and are required for racing). You will definitely want the hiking straps, because you'll mostly be single-trapping (crew only), and you'll want to be able to hike out.

I sail at the same weight as you. Takes a bit more wind to single-trap the crew (10-12 kts), more to double-trap (14-15 kts), but you can DEFINITELY fly a hull. You can actually do OK in light air. The moderate stuff is where you have no chance when racing against lightweights... <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />

Hope this helps.
