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]

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.
