Dutch shipyard building company Heesen has launched the second hybrid yacht in the 5000 aluminium FDHF class, combining conventional diesel propulsion with and efficient diesel-electric propulsion

YN 19150 – 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.

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

Hybrid Mode: Up to nine knots at noise levels of just 46dB, equivalent to soft rain. Two water-cooled DC electric shaft motors of 127kW each quietly power the yacht. The benefits are silent cruising and higher manoeuvrability in close quarters.

Economic Mode: Speeds of nine to 12 knots with main engines on and generators off. Ideal for longer passages, this mode comes with several interesting perks – frugal fuel consumption (at 12 knots the yacht burns only 98 litres per hour) and extended generator life.

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.

Italian designer Cristiano Gatto created a contemporary interior that exudes a sense of elegant calm.

The flowing, organic curves of custom furniture and low cabinetry allow guests to enjoy spectacular vistas from the floor-to-ceiling windows flooding the interior with natural light. Dark oak flooring and mullions contrast the pale colours of the panelling and cabinetry to emphasise space through the yacht while the grand staircase adds just a touch of drama.
