For a number of years I raced a Nelson Marek 36 plus. I had the boom extened 4 feet and the mast was lengthened 6 feet., with extra support added between the mast step and the keel. custom made North Sails, and a folding prop for motoring around the marina. The boat weighed in at approximately 13,000, and had a draft of 6;11 Very fast boat, especially in a jibing duel.. Also raced an Olympic class 6 meter called a flying dutchman, and of course, the obligatory Hobie Cats. I enjoy the "J" boats too, great light air boats. Not as fast as a hobie 33 in a puff.. but still a good boat.
