E- motion Hybrid systems use premium materials, advanced software, and high-performance battery technology to deliver one of the most advanced electric propulsion systems on the market.

Full Parallel Hybrid - 10 Functional Modes
1. Full-Diesel Traditional Propulsion
In this mode, the yacht can be operated traditionally, even if the hybrid system is off: both in hardware and software
2. Diesel-Electric Navigation Mode
Main diesel engines are off
Variable speed generators produce electrical power to operate the electric motors
Top comfort medium/long range navigation
3. Zero-Emissions Navigation Mode
All the internal combustion engines are off
Only the high voltage batteries supply power to the electric motors and to the Hotel Load
Zero noise while cruising
Zero pollution
4. Economy Navigation Mode
Only one main diesel engine is on
The engine supplies power to the system through the alternator mode of the electric engine
Both shafts are operative as one is powered by the main diesel engine and the second one by the electrical motor
In this mode, the electrical power for propulsion, Hotel Load, and the battery charge is generated by the shaft alternator
Both the generators can be switched off
Measured overall fuel savings up to 30%
Engine running hours drastically reduced
5. Power Booster Mode
The electrical motors and the diesel engines are working together on the same shaft
Increased acceleration up to 25% or more (depends on the hull trim)
Top speed Increased up to 3.5 knots
In this operation mode, both main diesel engines and all gensets diesel engines are working at 100% load
6. Cruising Booster Mode
The electrical motors and the diesel engines are working together on the same line shaft
In this operation mode, both main diesel engines and all gensets diesel engines are working at 80% load (continuous rating)
Increased cruising speed to the top speed of a traditionally operated yacht
7. Hotel-Load Zero-Emissions Mode
Lithium-ion batteries supply energy for all of the electrical systems of the yacht
At anchor, the yacht is fully operative up to 12 hours with all the diesel engines off
Top comfort
Zero noise
Zero pollution
8.International Shore Power and Plug-in Battery Charge Mode
While at the dock, the hybrid yacht has worldwide electrical shore power compatibility and charges the Lithium-ion batteries
No need for extra shore power converter
Save fuel for the next day at anchor
9. Generator Fast-Charge Mode
Main diesel engines are off
Variable speed generators operate at high speed to provide the power for a fast charge of the batteries and hotel load
Batteries will reach 90% charge in as little as 30 minutes
10. Navigation Fast-Charge Mode
Main diesel engines are on
Variable speed generators are off
The electric motors attached to the main diesel engines generate the power for the hotel load and charge the batteries to 90% in as little as 30 minutes

Select an e-Motion Hybrid system and discover all the advantages and benefits
Traditional diesel direct shaft propulsion remains unaltered
Fuel consumption is reduced up to 30% in Economy Navigation Mode
Long-range destination transfer by your crew at the lowest cost
Reduce engine running hours on propulsion engines and generators
Fast batteries charging: 90% charge in only 35 min. or less
International worldwide shore power compatibility
Our hybrid system is maintenance-free. Only the dedicated water cooling pumps require service
Permanent magnet technology of the electric engines and alternators: lightweight + power on-demand
Increased performances through Power Boost Mode
Higher resale value of the vessel
Enjoy the sound of the sea
The hybrid motor yacht becomes as silent as a sailboat while cruising in Diesel-Electric and Zero-Emission Mode
Silent fishing/trolling in Full Electric Mode. Reel in your fish without breathing noxious exhaust fumes. Enjoy the sound of the ocean while fishing
Noise-free dining and guest entertainment, even while cruising
Reduce environmental exhaust and water pollution
Drastically reduce your vessels yearly CO2 emissions
Improved Quality of Life On Board
Avoid waking sleeping guests in cabins by turning on diesel engines. Silently depart to your destination in Electric Zero-Emissions Propulsion Mode.
Full electric navigation in the medium range - or with the push of a button - switch to Hybrid Navigation Mode
After mooring, turn off your generators and run your yacht on battery power
In zero pollution, enjoy the peaceful sound of the sea instead of the hum and vibrations of the generators
Zero-Emissions Hotel Mode enhances the enjoyment of your favourite place on board: the swimming platform and aft deck
Play and swim in the sea behind your yacht without noxious exhaust fumes and noise from generators
