Heesen Yachts is proud to announce that on 1 July 2017, the world’s first Fast Displacement motor yacht equipped with hybrid propulsion was delivered to her Owner in international waters.
HOME (formerly Project NOVA) – a 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. Heesen is renowned for its meticulous attention to weight reduction and HOME is an effortless embodiment of this; being lighter than predicted, she is the perfect demonstration of Heesen’s signature capabilities.
HOME will début at the Monaco Yacht Show from September 27 to 30, 2017.
