Heesen Yachts' biggest ever project...

Design

This Heesen 6500 is based upon an ultra-efficient fast-displacement hull form (FDHF) developed by Van Oossanen & Associates (Holland) and successfully tested recently at the Wolfson Unit in Southampton (UK).

SEPTEMBER 2010

Tank tests showed that in comparison with traditional hard chine and round-bilge hulls, the FDHF (fast-displacement hull form) improves vessel efficiency by around 30 per cent. The hull’s shape and slenderness result in a very low wave profile over the entire speed range, while also improving sea-keeping and manoeuvrability. As a consequence, it could have a significant impact on running costs, not to mention reducing carbon footprint.
The exterior design of this 65m (213ft) has been handled by Heesen favourite Frank Laupman of Omega Architects, which do doubt is why the Heesen DNA is so obvious in those lines.
Notable design features include a touch-and-go helipad forward and a semi-shaded area aft which surrounds the swimming pool on the main deck. On the lower deck is a vast beach club area, whose design incorporates bar, sauna and hammam. In addition to the large transom platform, there is a side balcony that opens from the hull to the port side to provide the owner and his guests with an even closer connection to the sea.
She will be the Oss, Holland-based yard's biggest project by a considerable margin. Thus far its biggest launches have been 50m (164ft), although it has a couple of 55m (180ft) projects in hand presently.
We understand an order has been signed and delivery will be for late 2012/early 2013.
