While looking over the Portsmouth Ratings, I took out the boats that are in the Notice of Race and all the boats that do not fit the 70 or less parameter. Then you are down to possibly getting a class of F-16s, Tornados, Hobie 20s, F18HTs, or a portsmouth (which is not listed) There are other boats that fall into that catagory but the are not sailed (read raced) much anymore, that I know of. Including in the Performance line, Nacra 5.8, 6.0, Prindle 18.2, 19. The big class, Hobie 16s are not allowed? I thought that was a bold choice, but maybe there are not many of them in your area.
