Energy Observer is a floating laboratory, [8] destined to test an innovative energy architecture in extreme conditions, to prove its feasibility onshore. The energy system encompasses 3 renewable energy sources (sun, wind and hydropower) and two types of storage (li-ion batteries for the short-term and hydrogen for the long-term).
The increased low wind capabilities of optimized, modern devices enable downwind steering down to 1.3 m/s apparent wind and 1.5 kn of boat speed [8] [9] – properties that make an electronic steering device nearly redundant and enable crossing the doldrums under wind vane self-steering. An increasing number of long distance regatta sailors are ...
The 12 Metre class was used in the Olympic Games of 1908, 1912 and 1920 but few boats participated in these events. The 12 Metre class boats are best known as the boat design used in the America's Cup from 1958 to 1987. Competitiveness between boats in the class is maintained by requiring the boats to be in compliance with the 12 Metre formula.
While consuming only a fraction of the energy generated before, the generator now acts as a motor and reels-in the tether. [12] The system continuously repeats this process, flying the kite at an altitude of 200 to 400 meters. Energy generated by the Airborne Wind Energy System can be fed into the grid, stored in batteries, or directly consumed.
Nicknamed "Lego Boat" because the yacht (keels, rigs, rudders, bustles) could be set-up in different configurations as a 12 Meter. She portrayed Boomerang and later Platypus in the 1992 film Wind and was in the TV series "No Boundaries". In 2015 the New York Harbor Sailing Foundation signed a deal to acquire US 42, the sister-ship to America II ...
Australia II (KA 6) is an Australian 12-metre-class America's Cup challenge racing yacht that was launched in 1982 [1] and won the 1983 America's Cup for the Royal Perth Yacht Club. Skippered by John Bertrand , she was the first successful Cup challenger, ending a 132-year tenure (with 26 successful defences) by the New York Yacht Club .
This new general underbody type, with relatively minor refinements, was used on every subsequent Cup boat until the 12-metre Australia II ' s winged keel of 1983. Above decks, Intrepid featured a very low boom, made possible by locating the winches below decks.
Weatherly is a keel sloop designed to the 12-metre Rule. She was designed by Philip Rhodes and built by Luders Marine Construction Company at Stamford, Connecticut in 1958 for a syndicate of owners formed by New York Yacht Club members Henry D. Mercer, Cornelius S. Walsh and Arnold D. Frese.
