The design and construction of a 140 foot ketch at Royal Huisman Shipyard presented a unique prospect for designer and builder. In answer to a design brief calling for exceptional performance under both sail and power an extensive research programme was commissioned involving the Dutch Technical University at Delft and the Wolfson unit in Southampton. Both tank testing and computer velocity predictions were carried out to optimise all aspects of performance with special consideration being given to both stability and sailing balance. The result of this work confirmed the most optimistic design goals. Displacing 230 tons and carrying 825 square metres of sail, the sailing loads were clearly going to be significant to say the least. Ron Holland Yacht Design and Royal Huisman Shipyard developed the construction in concept and detail with Lloyds to assure unquestionable structural integrity. The lower hull floor sections are welded to fore and aft girders to create integral fuel and water tanks. At the top right of the photograph is the lower keel structure which has already been fabricated. Derived from America's Cup tank testing the keel, with a depth of 17 feet supports a 34.5 foot long bulb which will encase 64 tons of lead ballast.
