SP, the marine business arm of Gurit, has been approached and is heavily involved in the next generation of racer-cruiser, with Rogers Yacht Design's latest project. SP is providing the the structural design, engineering and materials for the dual-purpose Rogers 82. Dual-purpose as it incorporates the light weight and modern technology of a racing yacht with the luxury of a cruising vessel.
Currently at the halfway point in the build process at Goetz Custom Boats in the USA, this "thoroughbred high-performance yacht of only 30 tonnes" is steadily taking shape. The Rogers 82 will feature a flexible 4 cabin "superyacht interior" with a silent-running capability for relaxed performance cruising. The build – which is constructed entirely from pre-preg carbon – is the result of a period of intense structural design in association with SP.
With high performance in mind, a unique package of structural materials has been selected by the composite specialists, including SE70 Prepreg, supplied specifically with a large proportion unidirectional for optimum structural performance. The hull – which is now fully structured – is mainly a sandwich construction utilising SP’s carbon skins and P-Grade Corecell™, while the deck has been dry fitted enabling systems and interior fit-out to begin.
SPRINT® has also been specified by SP for use on some components of the Rogers 82 for its better performance and ease of lamination. As one of the unique composite technologies developed by SP, SPRINT® results in a patent-approved, award-winning product range, which the company considers to offer exceptional finishing and performance properties, perfectly suited to this new design.
With Rogers transferring many of the technologies they use in their racing yachts to the Rogers 82, SP has also worked closely with the design team to select materials that will guarantee a light, stiff and robust structure. Ampreg22 resin is used for wet-laminated parts and the epoxy structural adhesive SP345 is used throughout the boat for its high strength and toughness. SA70 adhesive film has been selected to bond the core due to its many advantages over traditional wet lay-up techniques.
SP’s Design Engineer, Dr Paolo Manganelli, has been involved in the structural design of the build since the start: “SP engineers have worked in very close collaboration with the designers at Rogers and the yard at Goetz to achieve the ultimate weight efficiency for this impressive yacht. The main challenge for the SP team was to meet the request for optimum structural performance and efficiency while retaining a comfortable interior layout and cruising boat-type ergonomics. Where typically metal would be used for other racer/cruisers, a large number of components have been engineered and manufactured using carbon fibre-epoxy composite to produce this inspiring dual-purpose yacht”.
The launch of the first Rogers 82 – christened Aegir – is scheduled for Spring 2010 with the composite structure due for completion by Summer 2009.
