Heesen 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. Name M/Y Home and formerly Project Nova, YN 17850 is a fifty meter all aluminium super yacht below 500 GT with shallow draft and it 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 YN 17850 easily exceeded her contractual maximum speed of 16 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. Heesen YN 17850 is not only ultra-quiet, but she is also extremely fuel efficient. At 12 knots, she has a fuel consumption of 98 liters per hour excluding generators and at ten knots in hybrid mode this further reduces to a staggering 45 liters 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 YN 17850 is an effortless embodiment of this; being lighter than predicted, she is the perfect demonstration of Heesen’s signature capabilities. Heesen 50m YN 17850 will debut at the Monaco Yacht Show at the end of September.
