After we heard that Spirit of the East was nominated for a World Superyacht Award in the category Best Sailing yacht in 30 to 44m range we did some research on this 30m Ketch. We came in touch with naval architect Stuart M Roy and he was happy to tell us more about this new sailing yacht.
“We were very pleased to have been invited by the British owners of Spirit of the East to provide design and consultancy services to this project over the last two and a half years”. This fabulous 30.48m (100ft) LOA, 100 tonne, steel yacht was completed and launched at Aegean Yacht Services of Bodrum, Turkey in the spring of 2006 and completed motoring and sailing trials shortly afterward. She has a beautifully smooth hull and a superb interior finish, as well as many innovative features.
The yacht has been designed and built to the classification standards of RINA (Registro Italiano Navale) and the construction work carried out under their supervision. It is intended that the yacht will gain a charter certificate from the UK MCA (Maritime and Coastguard Agency) for Category 0 (unlimited) usage for 12 charter guests plus full crew.
Spirit of the East has the ability to make fast passages under sail or power. The yacht has a long slim hull with a tight turn of the bilge to enhance the transverse stability and sail carrying power without requiring excessively deep draught. The keel and rudder are aerofoil sections for good efficiency and the rudder is a partially-balanced spade type providing good control and manoeuvrability. The propeller is an AutoProp self-pitching unit for optimum efficiency under power and minimum drag when under sail. The powerful ketch rig features high-tech sails and running rigging controlled by Harken hydraulic winches and headsail furling systems for ease of operation.
With guest accommodation in suites, comfortable lounging cockpit areas, a luxury finish down below, stunning chestnut joinery and full air-conditioning, this yacht is expected to be very popular with charter guests.
Our contribution started with the design of the hull, rudder and keel to suit the original concept and preliminary general arrangement developed by the client. Then we were asked to design a sail plan and to assist with the deck plan and the accommodation layout, in addition to providing technical advice at all stages of the project. Particular emphasis was placed on the aesthetic aspects of the design.
Although the construction detailing was all carried out in the design office at the yard in Turkey, much of the naval architecture work including stability calculations, performance prediction, rig loading calculations and checking of the detailed mass estimates was carried out in the UK with both design drawings and technical information transferred between the two design offices using email attachments.
