Heesen has announced the sale of the first motor yacht to be equipped with Hull Vane even before the official presentation of this innovation to the yachting community. Created by Piet van Oossanen from van Oossanen Naval Architects, Hull Vane is a foil fitted below the hull that can reduce resistance through the water by 24% at maximum speed, achieving an average reduction in drag of nearly 18% over the entire speed range. In addition, Hull Vane also reduces the motion and acceleration of the yacht in heavy seas due to the damping effect of the foil below the hull. When the bow pitches upwards on a wave the foil produces an opposing upwards force at the stern, and vice versa when the bow pitches downwards into a wave trough. The result is a much more comfortable motion in heavy waves.
At a design displacement of 350 tons, YN 17042 will achieve 15.9 knots with 2 x 1080 kW of power from the engines. At the cruising speed of 12 knots, the power requirement is only 2 x 240 kW: the fuel consumption figures are correspondingly low. The exterior lines of this 42-metre motor yacht have been designed by Frank Laupman from Omega Architects. Laupman has created a new bow design that combines a lower hull profile and matching seakeeping behaviour with a relatively short overall length, because of a characteristic ‘knuckle’ at half height of the bow. Big windows of continuous glass further enhance the guests’ proximity to the ocean. Twelve guests sleep in six cabins: the Owners have two suites: one positioned on the upper deck aft, which includes a gymnasium; the second is traditionally located on the main deck fore and has a balcony on the starboard side, a studio and a large walk-in closet. The guest area on the lower deck features two twins and two double cabins all with private ensuite bathrooms.
This innovative yacht is due for delivery in 2014 and the project is going to be presented to the yachting community at the Monaco Yacht Club on September 19, 2012.
