A repeat client, the former owner of Windrose of Amsterdam, showed his trust in the Dykstra team to be the Naval Architects and designers for this new J-Class yacht. The award winning J-Class Rainbow is built in aluminum and designed according to the JCA (J Class Association) maximum performance rules, based on William Starling Burgess' lines of the original 1934 America's Cup winner. The hull is from Bloemsma Aluminiumbouw and she is finished at Holland Jachtbouw (HJB). Art deco interior by Dykstra Naval Architects who partnerd up with deVosdeVries Design for the interior design.

Dykstra Naval Architects have gained over 30 years of J-Class experience and where responsible for the rebuilds of the J-Class yachts: JK3 Shamrock V, JK7 Velsheda, JK4 Endeavour, performance refit of J5 Ranger, the new builds JK6 Hanuman and JH2 Rainbow and J Yankee on the drawing board. To keep the J-Class fleet and races alive and to encourage new build yachts to enter the field, new JCA maximum performance rules have been developed, including allowing aluminum as building material. The new rule is a VPP (Velocity Prediction Program) based rating system which puts limits to the performance. This new rule has been developed by the Dykstra Naval Architects office and the Wolfson Unit in Southampton. The aim of the JCA, the Dykstra team and the rule is to bring fair & close racing to the fleet and to give all designs a chance of winning (on a handicap based system). Over the years the Dykstra team gained an enormous amount of hands-on information by racing on all the Dykstra J's in the current fleet.
