Heesen lays the keel of its biggest-ever project...

Yard Updates

She’s a 65m fast-displacement motoryacht destined for a Bannenberg & Rowell interior.

FEBRUARY 2011

Heesen Yachts has started laying the keel for 'YN16465', its largest-ever new-build. She’s a 65m (213ft) fast-displacement motor yacht. The ceremony took place in Shed 6 – the fabrication shop – at Heesen’s shipyard in Oss, The Netherlands.
This hull is due for completion in January ‘12, exhibits some interesting new techniques in the construction of its decks, bulkheads and part of the superstructure plating. Extruded aluminium plates of 300mm wide are welded together using a ‘friction-stir’ technique to form huge plates of 2.5x12m; effectively they are welded without filler rods. This method, developed by NASA, has the enormous benefit of creating less heat during the welding process. The result is a large plate with uniform mechanical properties and much fairer and smoother construction.
When combined with smart naval architecture, this improved construction technique results in a vessel that is 30 per cent more efficient than a round-bilge motor yacht. This vessel’s advanced design combines narrow beam and a special hull form to result in a very low wave profile over the entire speed range, while also improving its sea-keeping and manoeuvrability. This will translate into reduced running costs and less environmental impact.
Bannenberg & Rowell is responsible for her interior design.
“To complement such a dynamic and sleek exterior, we knew that we would have to produce an interior with the same qualities,” says Dickie Bannenberg. “We have already begun concept work on the main-deck saloon and dining areas and now very much look forward to designing the really exciting beach club, which will be located beneath the pool. An ‘infinity loop’ floor plan allows for neat zoning of spaces, with living and seating aft, dining forward and a free standing bar positioned opposite a fireplace, thus making dramatic design capital out of this potential ‘no-man’s land’ located amidships between the engine room air ducts.”
Having been signed during summer '10, YN 16465 is due for delivery in June 2013.
