Heesen Yachts have released the concept design of their 65 Metre based on a revolutionary hull intended to increase performance and reduce its environmental impact by focusing on the yacht’s entire speed range rather than just the maximum.



This Fast Displacement Hull Form (FDHF) is the result of studies and tank tests carried out over 20 years by the Dutch Naval Architects Van Oossanen and Associates.



The naval architect Perry Van Oossanen explained the idea that led the VOA team to create the FDHF design, “The typical load profile of a motor yacht often consists of long range cruising at low speeds and only short periods of time at higher and maximum speeds. This indicates the need to focus hull design over the entire speed range rather than on maximum speed only. The FDHF incorporates design features that have a large effect on hydrodynamic resistance over the whole speed range, such as the area of the immersed transom, bulbous bow, trim control and spray rails.”



Fabio Ermetto, Sales and Marketing Director at Heesen Yachts said, “Heesen Yachts is well known in the yachting industry for being a shipyard that likes challenges. We are proud to be the first shipyard to build a yacht featuring this innovative hull configuration using aluminium for both hull and superstructure. The Fast Displacement hull configuration is the perfect platform for creating a new luxury yacht in which increased performance and reduced environmental impact begin with the hull design.”



The Heesen 65 Metre Fast Displacement design offers some notable luxury features, such as a duplex beach club (located aft on the main and lower decks) with a 10 square metre side-balcony and a 22-square-metre swimming platform. On the lower deck of the duplex beach club there are a sauna, hammam, shower room, day head and a fully equipped bar.



Another notable feature is the glass bottomed swimming-pool located on the main deck allowing the natural light to glimmer through the water to the bar area beneath.



On the fore deck, the large sunbathing area can be transformed into a touch-and-go heli-deck. The tender garages with gull-wing doors are also located beneath the fore deck.



The exterior lines of this revolutionary Heesen 65 Metre Fast Displacement have been drawn by Frank Laupman from Omega Architects. The design clearly shows the Heesen bloodline, while invigorating it with the muscular appearance of a racing car.



Frank Laupman said, “We found a way to integrate the hull with the main deck element of the superstructure, by eliminating its normal overhang of the aft deck. On top of this integrated two-deck body, we developed the freestanding superstructure, which contains only the wheelhouse deck and the sundeck. Helmet shaped, it has no side deck overhangs and slopes down towards the stern.”
