Green Marine has today launched the first boat to be built to the exciting new Wally Cento class rules at its facility on the south coast of England. The latest innovation in the Wally lexicon of superyachts that are designed to be genuine cruiser racers, the new 100ft Hamilton III has been built for experienced racing yachtsman Charles Dunstone, whose previous racing boats have included the Reichel Pugh 76 Enigma, a Judel Vrolijk TP52 and the 36m Briand Hamilton II. Designed within a box rule by Judel/Vrolijk and with an interior by Design Unlimited, Hamilton III is an exceptionally sophisticated composite yacht built to the most exacting weight limitations yet boasting a luxurious cruising interior with every modern convenience and comfort.

To meet both the technical requirements and the remarkably short time scale set by the owner required the services of one of the top composite yards in the world. A substantial number of factors led to the selection of the UK’s Green Marine, not least its outstanding facilities, long experience in building complex, Grand Prix racing yachts using composite materials, and its ability to manage and co-ordinate a wide range of specialist sub-contractors. Its proven track record of delivering boats on time and meeting the most exacting technical demands was also taken into account.

The construction and fit-out took place using two of Green Marine’s four new build boxes. Designed to provide the optimal environment for all the processes during the build of a yacht, these 38m long ovens are equipped with computer controlled air management systems that can be set to different modes including oven, dust extraction, solvent extraction, post curing and painting. It was this capability to process both composite and paint materials in a single facility that saved Green Marine several weeks during the build. The build box also provided two-floor access to the boat which greatly streamlined the logistics around the boat and an overhead handling system enabled the rapid installation of heavy machinery and systems. Green Marine is unique in having four such facilities side-by-side, giving it the capacity to handle multiple projects of this complexity simultaneously. Continued overleaf…/

While the fit-out work was underway, the CNC machines in Green Marine’s component department produced the tooling for the various components. The rudder, hatches, winch pedestals, sheave boxes along with critical deck components such as the pedestal, centre console and aft arch were laminated with carbon pre preg. The rudder stock was built as a solid part to achieve maximum stiffness at minimum width.

Meeting the exceptional challenges presented by the design was something that few yards could have achieved. The target displacement with a keel weight ratio of 50% could only be accomplished by using build methods refined at Green Marine over decades of building racing yachts in carbon fibre and an uncompromising focus on weight saving. Green Marine’s long established practise of integrating the client’s management team into its own internal structure proved itself to be as effective in the building of a racing superyacht as it has in the past for thoroughbred Grand Prix race boats. Owner’s representative James Stagg and Green Marine’s Richard Clampett together mastered the unenviable task of integrating a luxury interior and push bottom sail management systems into a high spec racing yacht. To them also goes the credit of finishing this boat on time and in just 15 months, although Green Marine’s highly experienced workforce played a major part with up to 38 technicians and engineers working on her at any one time.

Ultimately Hamilton III has been engineered and built to a standard that has not been seen before in this type and size of boat. As the first of her class she provides a unique combination of thoroughbred Grand Prix racer and luxury cruising yacht with a premium quality interior executed to the highest levels of craftsmanship. Her successful completion further consolidates Green Marine’s position as a global leader in the construction of high performance sailing yachts.
