The propulsion system uses a generator driven by a hydrogen-diesel internal combustion engine which can be operated by either hydrogen or diesel oil to provide power for the Azipod units. At a speed of 10 knots, operating on hydrogen mode, the yacht has a range of more than 3,500 nautical miles. At speed of 18 knots it can reach more than 1,800 nautical miles. The forward slender spaces in the yacht are used efficiently for the storage of hydrogen tanks and tender boats.
Diesel capacity is 170,000 liters; liquid hydrogen fuel capacity is 220,000 liters.
The yacht is based around an advanced slender hull form with an axe bow, offering lower resistance due to low angle of entrance, excellent sea-keeping and a range of up to 13,000 nautical miles. The hull design is to have a minimal surface and hull wake, thus reducing its impact on sensitive marine life as well as shoreline erosion.
