Future Boat Propulsion

Flying Yacht By Yelken Octuri

For last year’s Aircraft of the Future show at the Air and Space Museum in Paris, designer Yelken Octuri concepted a seaplane-convertible trimaran sailing yacht. Octuri, who works as an interior designer for a plane manufacturer in France, designed a sailing yacht that can transform into a plane thanks to its four mobile masts. The sails are retracted and the four masts are lowered to become wings.

According to the designer’s site The propulsion is provided by the sails of the four masts in Boat mode. The surface of the sails is 1,302 sq. m. Each mast can be individually oriented through a double-jack system that ensures an optimal positioning regardless of the wind direction. In order to transform into wings, the masts must be lowered in horizontal position. The sails will then go to storage compartments located inside each mast. The four masts are lifted and lowered by a set of four shrouds set up on two central masts. Four dual propellers “Nissen & Brasseur” powerhead engines take care of the propulsion in Plane mode.

ICOMIA's First International Hybrid Marine Propulsion Conference

In the first conference of its kind, ICOMIA will report all aspects of hybrid marine propulsion systems in detail. The 1st ICOMIA International Hybrid Marine Propulsion Conference is to be held immediately prior to METS on Monday 14 November 2011. The conference will review the technical issues surrounding the design and implementation of marine hybrids and provide objective data on their advantages and disadvantages. It will draw heavily on new information from the EU-funded HYMAR project.

The marine industry still has much to learn about these technologies and the HYMAR team has tackled the challenge by taking a systems approach. From energy generation and storage, right through to propulsion motors, propellers and control systems, HYMAR has reviewed all of the critical elements.

Historically, one of the major issues has been integrating the broad array of technologies necessary to produce a complete system. To achieve this holistic view, HYMAR has brought together nine partners from across the EU with all of the skills necessary to develop, not just the specialist components, but also the underlying systems architecture and control system.

The presentations will be of interest to anyone considering investing in hybrids including boat builders, equipment suppliers, systems integrators and naval architects. 

Speakers include Malo Yachts, Mastervolt, Steyr Motors, J&J Marine, Homewood Products, Bruntons, INSEAN, Triskel Marine and ICOMIA. Mr Jean-Jacques Woeldgen form the European Commission will present the EU policy context.

Nigel Calder, Technical Director of HYMAR said: “ HYMAR’s analysis of hybrid systems cuts through misinformation in the marketplace to define the challenges is a great opportunity to discuss its future direction.”
