Followed the posts and thought I might jump in. I have an ARC 22 , actually my second one, and have been sailing them for 6-7 years now. Absolutely great boat with tremendous performance potential. I race the local events with my girlfriend and do all my day sailing with her as well. Real serious big events and I have a good friend sail with me as the chute can be a handful when it blows. I find the 22 to ideal in our conditions.... 10 up to 15 knots and shes a joy. The rig is so controllable that we can effectively flatten the main and jib and be in good shape into the upper teens . The biggest problem I see is some of the 22 sailors are conservative and might be tentative when it blows.....time on the water and you get comfortable in the breezes. Let me know if I can help with specifics. Its a great boat and quite frankly the rating is very winnable...we do quite well even when we screw up and thats against tough sailors in fort walton and pensacola.
Hope this helps!
