Designer Luca Brenta wanted a fast, affordable one-design class. Following these guidelines, the boat is constructed with vinylester resin and fiberglass vacuum bonded over an Airex core. The steel keel has a lead bulb, and class rules specify an aluminum mast, Dacron main, and 105-percent jib. The $31,000 price includes sails. The 470-sq. ft. asymmetric spinnaker is extra.
