Following the positive results of the tank test completed at the Wolfson Unit in April 2010, Heesen Yachts is proud to present the revolutionary 65 Metre concept based on the Fast Displacement Hull Form (FDHF). The FDHF is the result of studies and tank tests carried out over 20 years by the Dutch Naval Architects Van Oossanen and Associates. Perry Van Oossanen comments on 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 says: “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.”
