Heesen has delivered the YN 18250 White.

At 50 meters, with a Gross Tonnage just below the 500GT threshold, this semi-displacement motor yacht is the latest in the award-winning 5000 Aluminium class.

Extensive sea trials took place in the North Sea in good weather conditions, with waves up to half a meter. Seventh in the 5000 Aluminium class, White proved to be very responsive during her sea trials, reacting to steering commands instantaneously thanks to the large rudders in conjunction with the power steering unit.  Her powerful bow thruster in combination with the propellers optimized for her speed range, allow the vessel to be maneuvered with confidence in close quarters even in windy conditions.

Heesen’s acknowledged expertise in weight reduction, combined with two high power-to-weight ratio MTU 2,880kW engines, has proved to be a winning formula once again. The maximum contractual speed of 23 knots was largely exceeded, while at the same time vibration tests proved White to be extremely quiet.

A sister ship of White – YN 18750 Project Aster – is currently under construction at the shipyard in Oss and is available for delivery on June 30, 2019.
