Steeler Yachts - Havgap

The Steeler 61S Attétude is the world’s first fully electric and seaworthy prestige motor yacht. The triple decker ‘Flat floor Panorama Concept’ also adds the title of most spacious motor yacht in all its length. What more proof is needed that ultra-comfort really can go hand-in-hand with sustainability? This is a truly unparalleled combination.

She is a one of a kind motor yacht. Built according to our ‘single level living’ concept awarded European Powerboat of the Year. We have pulled out all the stops in accommodation, comfort and luxury, to convince even the most discerning watersports enthusiast that a water-borne villa really does exist under the 20m ship length.

But let’s start with the unique drive technology of the Attétude. We all know that the days dominated by fossil-fuelled ships engines are coming to an end. Instead, we are seeing bio-fuels, the possibility of hydrogen and most certainly electro-motors. While such progress may not be everybody’s cup of tea, it can certainly do no harm. On the contrary. The dimensions and weights are smaller than those of combustion engines, while their power continues to reach new heights. Batteries have become lighter and stronger with greater charging capacity and therefore quicker charging times. The costs of charging batteries are now also attractive, and even free of charge in some ports (in Norway for example)!

Furthermore, an electromotor powered by a generator is considerably more efficient than a conventional diesel engine. Even during the charging period for the batteries therefore, the Attétude is more economical than a traditional diesel engine.

With today’s state of technology, there is no other motor yacht with a more limited ecological footprint than the Steeler 61S Attétude.

The engine space of the yacht contains a state-of-the-art drive system, comprising a lithium-ion powered electromotor. The battery sets comprise 18 containers, each with 16 cells, sufficient for an action radius of 4 hours’ sailing. Out on the ocean waves, a diesel generator provides the power. The batteries are charged in two hours, so that the generator only needs to work two hours during a full 10-hour sailing day. The Attétude also features solar panels for a permanent and natural power supply.

The triple decker design of the Attétude makes it an impressive looker. Its silhouette is shaped by the bows and the streamlined length of the hull itself. Add to that the coupé-style cabin tapering backwards, with the flying bridge towering on top.

The principle of the triple decker ‘Flat Floor’ design of the Attétude is based on the Steeler vision of ‘single level living’, whereby the owner has full command of the saloon, galley and master bedroom on the single level middle deck, over the entire length from fore-to-aft, without any stairs or height differences.

The top deck houses the wheelhouse with entertainment area, freely connected to the open rear deck. The lower deck is home to two guest cabins, each with its own bathroom.
