High-performance sailing is achieved with low forward surface resistance—encountered by catamarans, sailing hydrofoils, iceboats or land sailing craft—as the sailing craft obtains motive power with its sails or aerofoils at speeds that are often faster than the wind on both upwind and downwind points of sail.
During his time as the meteorologist for the Australian sailing team at the 1976 Summer Olympics in Montreal, Quebec, Canada, Bethwaite collected copious wind data that led him to write his first book, High Performance Sailing. In 2008 he followed this up with a further volume, Higher Performance Sailing, also published by Adlard Coles Nautical.
The 29erXX is a high performance sailing skiff, it was designed to allow light crews, particularly female crews, to sail twin trapeze boats and as a training boat for the more powerful 49er. The class gained International Sailing Federation Class status in May 2011, but lost it in 2014. [1]
The 29er is a two-person high performance sailing skiff designed by Julian Bethwaite and first produced in 1998. Derived from the Olympic class 49er class, it is raced in the ISAF Youth Sailing World Championships. [3]
High Performance Sailing. Waterline (1993 ed.), Thomas Reed Publications (1996, 1998, and 2001 eds.), and Adlard Coles Nautical (2003 and 2007 eds.). ISBN 978-0-7136-6704-2. The book also covers the history of the 18 ft Skiff and of high-performance sailing in general, as well as the sailing techniques required to achieve high performance.
The boat has been an Olympic class since it was selected by the International Sailing Federation to be the men's high performance double handed dinghy Sydney Summer Games of 2000. Its derivative featuring a re-designed rig, the 49er FX, was selected by World Sailing to be the women's high performance double-hander at the Rio Summer Olympics of ...
High-performance catamarans, including the Extreme 40 catamaran and International C-class catamaran can sail at speeds up to twice the speed of the wind. [ 18 ] [ 19 ] Sailing hydrofoils achieve boat speeds up to twice the speed of the wind, as did the AC72 catamarans used for the 2013 America's Cup .
Sailing skiffs have developed into high performance competitive classes. Many of today's skiff classes are based in Australia and New Zealand in the form of 12 ft (3.66 m) , 13 ft (3.96 m), 16 ft (4.88 m) and 18 ft (5.49 m) skiffs .
