Dykstra Naval Architects from Amsterdam took on the job for a repeat client to design the replica of this biggest J ever built to date. Hanuman (Endeavour II) is built in Alustar with a Carbon mast at Royal Huisman Shipyard, not a stranger to the J-Class yachts. In 1989 J-K4 Endeavour was re-built at the yard in Vollenhove. Dykstra Naval Architects were also responsible for the design work of this re-built. Hanuman has a Pieter Beeldsnijder interior. Design and building of Hanuman have been according the maximum performance rules of the JCA (J Class Association). Hanuman is the first new J built and launched in The Netherlands.
Below decks, by contrast, interior designer Pieter Beeldsnijder has drawn upon traditional materials and period design references to create all the warmth and ambience of a bygone era using French and American Walnut.
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.
