New Rainbow Project:

Amsterdam, The Netherlands, October 20, 2009 (Press Release)


New J-Class Yacht Rainbow, based on the 1934 America's Cup Defender. Drawing: 2009 Dykstra & Partners

J-Class Rainbow update, building has started

The J-Class Rainbow, designed by Dykstra & Partners for a repeat client, has started building at Bloemsma Aluminiumbouw. When the hull will be ready, Rainbow will be transported to be finished at Holland Jachtbouw (HJB).  The re-build of this originally William Starling Burgess designed yacht will be under supervision of Dykstra & Partners Naval Architects, who also have been responsible for the re-builds and refits of the J-Class yachts: Shamrock V, Endeavour, Velsheda, Ranger and the soon to be sailing new J-Class Hanuman (Endeavour II project).  Rainbow will be built and fitted out to race with the existing and new Js according to the JCA (J Class Association) rules.  

Dykstra & Partners and the J-Class:

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 & Partners 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 Js in the current fleet.  

Dykstra & Partners have gained over 20 years of J-Class experience and where responsible for the rebuilds of the J-Class yachts: Shamrock V, Velsheda, Endeavour, refit of Ranger and the new build Hanuman (Endeavour II project). Rainbow will be the 2nd new J-Class in order for the Dykstra team. More new J-Class projects in design for clients and refits under supervision of Dykstra & Partners for current J-Class yachts are planned to take place in the coming year.
