VittersVitters Shipyard is continuing construction on 43.6m (143ft) J-Class Svea. Currently being outfitted, the yacht was originally begun at Claasen Shipyards before being taken over by Vitters. She will be the first J Class yacht launched from the Vitters Shipyard.

With naval architecture and exterior styling by Hoek Design Naval Architects, when launched, Svea will be the longest of all the Js. She is constructed in aluminium with an integrated traditional long keel. Her  hull construction is based on longitudinals on web frames, with high tensile frames and Alustar hull plating. Research by the Hoek Design office suggests that the design of J-S1 will be very capable, especially upwind.

Alustar hull plating offers greater corrosion-resistance and improved performance producing stronger, lighter, more durable hulls. It has a greater overall strength and, in particular, retention of strength after welding, than traditional alloy.

Svea’s owner’s brief called for a change in the original deck arrangement, to accommodate the equipment used in modern J-Class racing. The deck construction in the original design allowed options to be kept open for various interior and deck layouts. Svea’s interior will be designed by Pieter Beeldsnijder Designers & Naval Architects, and will have traditional styling in line with the overall character of the yacht.

Hoek Design redesigned the lines plan, strength and construction plans, using the original drawings by Thore Holm from 1937 as the basis. Today’s design is based on an aluminium hull and a 53.75 metre carbon fibre main mast. Svea will be one of the longest yacht construction projects with a design which began in 1937, more than 75 years ago.

The hull lines of the Svea project were originally drawn by Tore Holm, famous for his Meter Class designs in the 1930s.  Hoek Design redesigned the lines plan, strength and construction plans, using the original drawings by Thore Holm as the starting point.
