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, the 42m luxury yacht 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 the Heesen superyacht YN 17042 have been designed by Frank Laupman from Omega Architects. Laupman has created a new bow design that combines a lower hull profile and matching sea keeping 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.
