The exterior of Nova is designed by Omega Architects and it’s our second yacht with hybrid propulsion. In this case ‘Hybrid’ means that the yacht can draw on two sources of power for propulsion: diesel mechanical and diesel electrical. Either or both sources can be used at the same time. This provides less noise and vibration, a more flexible power management which means better efficiency.
Nova has a transatlantic range of 3,750 nautical miles at a cruising speed of 12 knots. Her top speed of 16.3 knots is remarkable for a displacement yacht of her size. The hybrid propulsion operates near-silent in electric mode. Moreover, Nova achieves lower fuel consumption and a higher top speed when the diesel engines and electric motors are combined
With our ever-increasing desire to minimise environmental impact, coupled with the enormous improvement in alternative power systems, Nova’s hybrid engine system embraces the very best of 21st century technology. The hybrid system offers irresistible advantages over a conventional diesel-powered system: it’s cleaner, quieter and more fuel efficient.
The engine can be operated in four different cruising modes depending on your priorities:
So you want to go places, but you’re not in too much of a hurry. Hybrid Mode will drive the yacht at speeds up to 9 knots, when the power is derived purely from Nova’s e-motors and the generators. With just a maximum of 46 dB(A) – the sound of softly falling rain - in the Owner’s stateroom, Hybrid Mode is beautifully silent and engine vibration is imperceptible because the generators are insulated and boxed. What’s more, fuel consumption is extremely low, running at no more than 70 litres per hour.
If you want to go a little faster, say between 9 and 12 knots, you have the option to switch off the generators and run off the main engines alone with the e-motors supplying the hotel load.
This is what you’d describe as the most conventional mode, when the main engines are driving Nova’s propellers along with the generators providing power to the Hotel Load, and the e-motor is switched off. In Cruising Mode, Nova is capable of speeds between 12 to 15 knots.
If you’re really in a hurry and want to hit the yacht’s top speed of 16.3 knots, Boost Mode will get you there. This is when you’re running on your main engines, the generators, and you’re feeding the e-motor on the gear box.
Sounds complicated? Well, the technology is complex, yes. But operation is simplicity itself. And the benefits - particularly when you’ve experienced the smooth and silent operation at lower speeds - are fantastic. For you and the environment.
