Construction
RCD Status: Our understanding is that the yacht is exempt from the essential safety requirements of the Recreational Craft Directive as she was built and placed into use within the EU prior to 1998.

Hull, Deck & Superstructure Construction:
- The yachts were designed to be exceptionally strongly built of steel in order that they could face all that the Southern Ocean might throw at them, with absolute confidence. The hulls are constructed of high tensile steel shell plating over “T” bar longitudinals and angle ring frames. A full depth skeg and ertalite bearings provide support for the steel rudder and good engineering ensures absolute reliability.
- The entire deck and superstructures are of stainless steel in order to reduce maintenance to a minimum.
- The stainless steel fuel, water and sullage tanks are provided with good access for cleaning. The International Paint coating systems are the best that current paint technology can provide with the result that on return from the world’s toughest yacht race, the yachts looked as if they had returned from a summer cruise.
- Above the waterline, the hull and deck are lined with approximately 60 mm of sprayed Polyurethane foam to provide thermal and sound insulation. The extensive use of Warerite laminates in the interior fit out, ensure light, bright accommodation, which is easy to maintain and keep clean. Maple hull liners and Afrormosa trim are highlighted by the white bulkheads and provide a warm comfortable feel to the accommodation.
