Heesen Yachts has sold its 50m (154ft), all-aluminium explorer yacht, YN 16750, which will be fully custom-built for delivery to the owner in 2015.

Based on the Fast Displacement Hull Form (FDHF) developed by Dutch naval architects, Van Oossanen and Associates (VOA), the superyacht can reach a maximum speed of 18.5kt with only two 1,000kW MTU’s installed, providing significant improvements in fuel efficiency. Space saved from carrying less fuel can be reallocated to provide the crew with valuable storage volume under the crew mess.

“Modest propeller tunnels have been defined allowing for 1.5m diameter propellers,” says Perry van Oossanen, naval architect at VOA. “The hull will be fitted with Quantum XT zero-speed fins and bilge keels, allowing for a maximum reduction in roll angle when at anchor. The design of the hull, appendages and propulsion arrangement has been focused on obtaining the best fuel efficiency possible without sacrificing performance and comfort when running in waves.”

The owner commissioned Frank Laupman from Omega Architects & AB Studios to design the exterior and layout with clean and elegant lines, which are emphasised by contrasting bands of wraparound glass, which Laupman describes as “complex simplicity”. The interior will be based on the colour contrast between swamp oak panelling and dark joinery details. Ten guests can be accommodated in five cabins.
