Renewable energies for a sustainable boat
But rather than likening it to an electric car requiring nightly charging, consider it more akin to an electric bike, where the motor complements and works alongside your sails, which after all should be the primary means of propulsion on a sailing yacht.
An essential point to highlight is that the batteries not only power the electric motor but also serve as an energy source for all onboard systems, allowing the “Smart Electric Solution” to seamlessly integrate with you how you live onboard.
In place of a large diesel engine, a hybrid electric motor is now installed, powered by a substantial bank of lithium-ion and phosphate batteries, charged by a 16kw generator.
Engaging “Silent Mode” allows for approximately 35-40 nautical miles of noiseless navigation, perfect for harbour manoeuvres or mooring.
When it comes to hoisting sails and harnessing wind power, there are instances where maintaining passage speed or navigating unfavourable winds becomes challenging. This is where the “Smart Electric” system shines. In “Hybrid Mode,” you can apply a discreet amount of silent electric power to assist your passage speed for up to 12 hours.
The charging system operates automatically, with the generator activating when battery capacity reaches 30%, typically replenishing the batteries in 4-6 hours. Additionally, the propeller acts as a hydro generator while sailing, contributing to battery charge. Solar panels can offer an extra charging source, and when docked, shore power can will also recharge the batteries.
Notably, the battery capacity supports overnight operation of a full air conditioning system without needing recharging, eliminating generator noise in peaceful anchorages.
In summary, Dufour’s “Smart Electric” solution seamlessly integrates with the boat’s systems, presenting a practical and enjoyable alternative to traditional diesel engines, ultimately enhancing your sailing experience and how you live onboard.
The Smart Electric version is available on the following models:
Dufour 530 – Dufour 470 – Dufour 44 – Dufour 41
