Hetairos the ultimate in superyacht propulsion

Heitaros_copySince 2009, OYS have been working in conjunction with Baltic Yachts and Marine & Hydraulics in Finland to custom design and manufacture a state of the art hydraulic propulsion system for the newly launched Hetairos.

With a facade of something you would expect to see on an old British Cutter Pilot boat, reality could not be further from first appearances. This magnificent Superyacht uses the most ultra modern day composite materials available, to ensure performance in comfort and style. Built to the owner requirements to have a Superyacht with a classic look, yet that was the largest and fastest possible yacht capable of passing through the Panama Canal.  As such you would be lead to believe her transom is made of the finest teak, yet this is actually carbon fibre, saving 100kg of weight. This is just one example of how modern materials have been used on this magnificent Superyacht.  

OYS have supplied 2 x 460hp hydraulic swing down retractable primary drives for Hetairos, the first of their kind in the world. Combined they generate over 14knts under power and provide a bollard pull in excess of 1100kgf. The units themselves rotate 360 degrees and are positioned either side of the centreline just aft of the keel, providing incredible manoeuvrability. Hetairos is built for performance, whether under sail or power, and therefore these hydraulic powered units fully retract into the hull within seconds when not in use, leaving a completely flawless hull as per the designs of Gerard Dykstra & Partners in association with Reichel Pugh Yacht Design.

OYS custom design, engineer and manufacture Sail Drive systems from 30-600hp on a project by project basis. They can be powered through hydraulics, electric or direct drive couplings, which deploy the leg drive through a vertical or swing down motion, all of which can rotate through 360 degrees. OYS will produce a product exactly to your requirements.

At 66.7m, Hetairos has been designed for performance, Baltic Yachts have entered new territory with her propulsion system and OYS and proud to be part of such a fine Superyacht.
