Design
[edit]The J/70 is a small racing keelboat, built predominantly of fiberglass. It has a fractional sloop rig, a transom-hung rudder, a retractable bowsprit and a lifting keel. It displaces 1,790 lb (812 kg) and carries 628 lb (285 kg) of lead ballast. The boat features a very large asymmetrical spinnaker with an area of 491 sq ft (45.6 m2), flown from the carbon fiber bowsprit.[2]
