allowed to be built under the new J-Class Association rules,” Hoek explains. “We analysed the line honours and handicap of all 20 yachts and modelled them in our software in such a way that we could predict performance. A specifi c handicap system was developed by the J-Class Association for these yachts in order to enable smaller and larger and steel and aluminium Js to race against each other. This analysis gave us a great deal of insight into the performance differences between these yachts.” “The best fi ve performing yachts were further analysed with computational fl uid dynamic software in order to gain greater insight into the differences. The series of yachts originally designed for the Ranger project in 1936 proved to be very good performance-wise, although some are better for light air conditions and others for heavy air.” Currently under construction are Rainbow, Atlantis
and Yankee, while a Swedish designed J, Svea, has line plans approval. The original Rainbow was the successful Cup defender in 1934, while Yankee was an unsuccessful defence candidate for the Cup in 1930. Atlantis is a Frank Paine design from back in the Thirties, that was never built, and it is again Hoek Design who have now interpreted the original lines. The list of regattas for this class grows each year, as does the fl eet, with England now on the circuit, expect to see more of these magnifi cent craft gracing our waters. CY
