Heesen’s first hybrid-propulsed FDHF motoryacht ‘Home’ exceeds expectations!

|

On 1 July 2017, the world’s first Fast Displacement motor yacht equipped with hybrid propulsion was delivered by Heesen to her Owner in international waters.  This 50m all aluminium motor yacht below 500GT with shallow draft, underwent intensive sea trials in the North Sea for five days in calm sea conditions, with waves of up to 0.5m and light breeze.

The results are impressive: not only has HOME easily exceeded her contractual maximum speed of 16.3 knots in the traditional diesel engine mode, but also expectations in her hybrid ‘silent cruising mode’.

Thanks to two 127kW water-cooled DC electric shaft motors, she exceeded the predicted speed of 9 knots with noise and vibration levels well below the specification levels.

HOME is not only ultra-quiet, but she is also extremely fuel efficient. At 12 knots, she has a fuel consumption of 98 litres per hour (excluding generators) and at 10 knots in hybrid mode this further reduces to a staggering 45 litres per hour, which for a 50m yacht, displacing 295 tons and with a Gross Tonnage of 499, is an outstanding achievement.

This impressive performance is achieved with just two MTU 12V 2000 M61 engines of 600 kW each, which are smaller than those typically fitted on a yacht of this size. This once again proves the remarkable efficiency of Van Oossanen’s FDHF (Fast Displacement Hull Form).  With a particular attention to weight control, HOME is predicted to achieve a transatlantic range of 3,750 nautical miles while cruising at 12 knots, despite carrying just 45,000 litres of fuel. This is  further underlining the remarkable efficiency of the FDHF (Fast Displacement Hull Form).

Despite being powered by relatively small engines for her size — twin 804hp MTU 12V 2000 M61s — HOME will still achieve a respectable top speed of 16.3 knots when powered by her main engines and the diesel-electric propulsion system will allow for silent cruising at up to nine knots. Smaller engines mean the yacht will also be more spacious, with less room taken up by the engine room. Interior stylist Cristiano Gatto worked closely with the Owner to create an interior décor that boasts a sophisticated linear design based on a two-tone palette.

The striking profile was designed by Frank Laupman of Omega Architects  and is considered a design delight with her vertical bow and characterising spray rails, to her stern with a large fixed swim platform, wide sweeping stairs leading to the main deck and floor-to-ceiling glass windows.

HOME will début at the Monaco Yacht Show from 27-30 September 2017.
