The aim of this participative wiki-type website is to take advantage of the well-named World Wide Web to collect and make public as much information as possible about the « 5.5 metre International Class » yachts, born in 1937, and to build up a documented history of the Class.
6096 documents, links and infos have already been uploaded and made accessible to everybody via the web, since the creation of this wiki in November 2005.

The very first « 5.5 metre » racing yacht design, and the Rating Rules issued from this project were created in 1937 by Charles E. Nicholson. However, the first unit built (K-1 « The Deb ») and launched conforming to these rules wasn’t until 1949, about eight years later. No further notes needed to explain that long gap…
Since that date, the successful « 5.5 metre » has not only been recognized as an « International Class » by the World Sailing association (named « IYRU » at this date), the but also by the Olympic Games Committee as an Olympic category for the games that held in Melbourne, Australia in 1956, until the last campaign in 1968 at Acapulco, Mexico.
Approximately 800 original and different boats have been designed, built and sailed all over the world by ca. 131 designers, 184 boat builders and more than 1578 owners over almost 34 countries to date ! What a record !
This heritage is now regularly preserved in two famous spots: the Yachting Heritage Center - Robbe & Berking Museum in Flensburg (GER) and the Musée du Léman in Nyon (SUI). [ Less ]
