J/70 is a trailerable, 6.93-metre (22.7 ft) American sailboat class designed by Alan Johnstone and first built in 2012.[2]

Production[edit]

The boat is built for J Boats by three builders, CCF Composites in the United States, J/Composites in Europe and J/Boats Argentina in South America.[3] At least 1451 had been constructed by 2019.[4]

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]

One thought on “Cannabaceae

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
