Electric / Hybrid propulsion
Conventional diesel propulsion is no longer the only option and neither necessarily the best choice. Nowadays, hybrid and electric propulsion is for many situation a viable and preferable option providing several significant benefits over diesel propulsion;
- Less maintenance and running costs
- More energy efficient
- Quiet and vibration-free operation
- Direct Control
- Sustainable and clean
- No diesel fumes
- No hassle with fuel and oil filters
- No risks regarding polluted diesel
- Clean engine room
An electric motor is far more efficient than an internal combustion engine. Some of the power of a conventional inboard is diverted to run equipment such as pumps and alternators. This means that an inboard rated at 30 horsepower isn’t delivering all the horsepower to the prop shaft. Electric motors don’t have similar power draws from auxiliary equipment. In general, you can get essentially the same boat speed from an electric motor as you would from an internal combustion engine rated at twice the horsepower.
Electric propulsion brings motorsailing a completely new experience. With the soft, almost unnoticeable hum of the electric drive, the yacht can be pointed much closer to the wind while still enjoying the quiet peaceful sailing that we enjoy so much.
There are many yachts with dated diesel engines that are in need of either overhaul or replacement. This is an excellent opportunity to electrify the ship by making a conversion. Removing and replacing the old diesel is recommended. The new electric drive can be mounted on the existing engine brackets and propeller shaft. As for power sources, a combination of solar, wind and shore is ideal. To extend the range of the ship the ‘standard’ battery bank’s (equivalent to diesel tank range) capacity can be increased (lithium Ion) or a quiet, clean and efficient generator can be added.
In case the diesel engine is to be maintained, a smaller electric drive can be added to create a hybrid system with the benefits of a silent, direct and odorless operation during short distances such as docking, entering and exiting marina’s, etc.
Working together with our specialized partner we join forces and combine the best of both worlds from our respective disciplines. The electric / hybrid propulsion systems are calculated based on the ship’s characteristics such as displacement, tonnage, size; 30ft / 40ft / 50ft / 60ft, as well as the type of usage; day sailingand cruising, weekends, holidays, long passages and blue water cruising.
