Dutch yachtbuilder Heesen Yachts has launched its second hybrid yacht in the 5000 aluminium Fast Displacement Hull Form (FDHF) class. YN 19150 – Project Electra combines conventional diesel with diesel-electric propulsion.

Project Electra is the successor to motor yacht Home, which received international accolades for its innovative and eco-friendly propulsion system and fast displacement hull design.

Four cruising modes

Compared to a traditional diesel engine arrangement, the hybrid power and propulsion system chosen by Heesen is quieter and more fuel-efficient. It offers cost-saving benefits and flexible power management as the yacht operates in four different cruising modes:

  • Hybrid Mode: up to 9 knots at noise levels of 46 dB. Two water-cooled DC electric shaft motors of 127 kW each quietly power the yacht. The benefits are silent cruising and higher manoeuvrability in close quarters.
  • Economic Mode: Speeds of 9-12 knots with main engines on and generators off. Ideal for longer passages and offers extended generator life. Fuel consumption at 12 knots is 98 litres per hour.
  • Cruising Mode: Speeds of 12-15 knots. This is the traditional mode, where the diesel engines drive the yacht’s propellers and the generators supply the hotel electrical demand.
  • Boost Mode: For top speed of 16.3 knots. Generator-powered shaft motors are brought into service alongside the main engines giving an extra kick of power to the gearbox.

Electra stays just below the 500 GT threshold. The profile was created by Frank Laupman of Omega Architects. A near-vertical bow, long waterline and extensive use of glass characterise its exterior lines. The layout offers plenty of outdoor living areas. Italian designer Cristiano Gatto created the interior design.


Twelve guests sleep in six staterooms with private en-suite bathrooms. Traditionally located on the main deck forward, the master suite comprises an office, a bedroom that spans the full beam and bathroom with large marble shower, large vanity and separate toilet room. The remaining guests reside on the lower deck in a full beam VIP, two twins and two double suites, all with direct access to a fully equipped gym with sauna aft.

Sea trials

After completing the commissioning of its systems, Project Electra will undergo intensive sea trials in the North Sea and is due for delivery in April 2020.
