(With video) Van Oossanen Naval Architects has developed the Hull Vane. This spoiler placed underwater on the hull at the rear creates thrust and thus saves fuel.
The Hull Vane is now patented and was awarded with a nomination for the HME Maritime Innovation Award. SWZ Maritime’s November issue features an extensive article on the Hull Vane, its developing process, the workings, its fuel saving capability and the first applications.

Fast Displacement Hull Form
Van Oossanen holds more patents than just for the Hull Vane. The company has also developed a new hull form, the
Fast Displacement Hull Form (FDHF). The development of this concept was triggered by the desire to develop hull forms that are efficient over the entire speed range and not only in a restricted speed interval around the maximum speed.
The FDHF is applicable to all vessels and out-performs conventional displacement and semi-displacement type hull forms at all speeds up to full “planing” speeds (in excess of a Froude number of 1.0).
At semi-displacement speeds, the resistance values displayed by the FDHF are 15 to 20% better than those of well-designed hard chine hull forms.
Other benefits of the FDHF, especially when compared to hard chine yachts, are improved sea keeping behavior and maneuverability, as well as a lower sensitivity to an increase in displacement.
