Next-generation on-board power
No battery. No generator. Complete silence on board.
‘When silence becomes a luxury.’
The first supercapacitor power system for yachting. No lithium, no diesel, no chemicals — and no noise from the generator whilst at anchor.
The solution
Another way to power your boat
Yacht Power replaces the diesel generator and reduces — or even eliminates — the need for a battery bank. All this is made possible by electrostatic supercapacitor technology: no more need for lithium.
Total silence
No noise, no vibration. A full night at anchor without the hum of the generator.
Zero emissions
No smoke, no odour, no burnt fuel. Comfort without the pollution.
Charges in 1 hour 30 minutes
1½ to 4 hours depending on the model, for a full 6 to 8 hours’ battery life. Whereas lithium batteries take 6 to 10 hours.
Chemical-free
Contains no lithium, lead or acid. Therefore, there is no risk of thermal runaway or fire on board.
Technology
The electrostatic supercapacitor
The same principle as in the rail and aerospace industries: energy is stored through an electrostatic effect, without any chemical reaction. Designed and assembled in Italy to withstand the marine environment.
20,000 cycles guaranteed
That is 4 to 7 times the service life of a lithium battery pack (3,000 to 6,000 cycles).
Intrinsic safety
No risk of thermal runaway, explosion or fire. No gases, no acids.
Operates between -20°C and +60°C
No accelerated ageing due to heat, unlike lithium at temperatures above 35°C.
Maintenance-free
No BMS to monitor, no cell balancing. No maintenance. 5-year manufacturer’s warranty.

100 per cent (calibrated to 95 per cent)
→ Equivalent performance, a service life four times longer, and no risk of fire on board.
The actual cost
When you buy, the price is the same. After that, the gap widens.
On a 15–18-metre yacht, compared with an equivalent diesel generator and lithium battery system, the initial investment is similar — but with every passing year, the returns work in your favour.

purchase price difference
With equivalent set-ups, you start on an equal footing.
≈ 30 %
total cost savings over 5 years
that is, a saving of nearly €19,400.
≈ 53 %
total cost savings over 10 years
that is, savings of over €51,700.
Assumptions: 300 hours of operation per year, 3.5 litres per hour at €1.40 per litre, generator maintenance ~€1,150 per year, replacement of the lithium battery bank in year 7.
Beyond the figures
Benefits that cannot be quantified, but are very real
Some benefits cannot be captured in a cost table. It is often these that make all the difference in practice.
Insurance premium
No more risk of lithium fires on board: a solid argument for negotiating your premium with your insurer.
Resale value
A Yacht Power fit-out enhances the value of the boat: premium technology, modern and sought-after equipment.
Ease of use
Complete silence at anchor = a full night’s sleep without the band. The number one selling point for a charter.
Carbon footprint
Over 1,000 litres of diesel not burned each year, equivalent to nearly 2.8 tonnes of CO₂ avoided — and no rare earths or critical metals, unlike in lithium.
Winter storage
No chemical precautions are required for winter storage, and there is no risk of deep discharge. You can leave the boat with complete peace of mind.
Minimal maintenance
No more draining, no more BMS to monitor, no more cells to balance. More time to spend sailing.

How it works
A smart, autonomous system
Yacht Power automatically manages energy sources according to the usage context.
01
Silent mode
Powers the whole boat without a generator: air conditioning, kitchen, electronics, lighting. Completely silent.
At anchor, whilst sailing, at night
02
Bypass mode (quay)
At the harbour, the boat is powered from the jetty whilst Yacht Power recharges at the same time, without any interruption.
At the port with a jetty connection
03
Power Assist
If the shore supply is limited (16A, for example), Yacht Power automatically makes up for any peaks in power consumption.
On undersized quays
04
Group self-management
If a generator is fitted, it only starts up when necessary, at full power. Less fuel, less wear and tear.
As an addition to an existing group
Supervision
Your whole boat, right in the palm of your hand
A true energy management hub, accessible via the 7" touchscreen on board or from the dedicated mobile app — wherever you are in the world.
Real-time monitoring
Production, consumption and state of charge, in real time.
Remote equipment control
Air conditioning, lighting, refrigeration… you maintain control over everything on board.
Integrated WiFi + GSM connectivity
Secure remote access from anywhere, and full usage history.
Automatic generator management
Manual or automatic start and stop, if a genset is present on board.
