Motor

All systems use a patented permanent magnet DC motor that operates at an efficiency up to 93%.
The high efficiency means less power consumption and gives the motorsolutions longer distance before the need for recharging.
Due to the high efficiency, the need for recharging after a shorter period of motoring is reduced. This gives the battery bank a unique long lifetime.

Console

The motor is mounted on a console, custom built to fit into a sailboats engine room. The console can reuse foundations from most diesel installations and is very easy to install.
As it requires less space than a diesel engine, boats with a small engine room, now have the possibility of having an inboard motor installed.

Gearing

We have chosen to use a belt reduction gearing instead of mounting the motor direct on the drive shaft. The gearing optimizes the efficiency of the motor to the most efficient RPM of the propeller.
The gearing improves torque and thereby acceleration.
Gearing reduces wear and tear of the engine dramatically and ensures a lifetime that by far exceeds the lifetime of a diesel engine.

Motor controller

The electronic motor controller is the heart of the system as it controls the power of the engine. With an average efficiency of 97%, the motor controller is along with the rest of the components used in the system, securing an optimal usage of the battery bank.
The motor control box is designed for easy installation so throttle, key lock, charger, battery monitor and DC-DC converter can be connected by plug and play.

Throttle

The motor solution comes with a waterproof, infinitely variable forward/back throttle making speed control and maneuvering easy and accurate. The throttle is ready for cockpit mounting.

Key Lock

The motor solution comes with a keylock ready for cockpit mounting.

Batteries

Batteries are the fuel tank of the electric motor system. As so it is important to choose the batteries that fit your requirements.

There are a lot of producers of batteries, but no matter which manufacturer you choose, please note that you must use batteries that can be discharged by 75-80% on a regular basis.
These batteries come in the following two groups:

Dry batteries:
AGM or Gel batteries:
Advantages: Maintenance free and near to none gas when charging.
Disadvantage: Less charging cycles than by wet batteries.

Wet Batteries:
Semitraction (flat plate) or tubular.
Advantages: Lower purchase cost and more charging cycles
Disadvantage: Maintenance must be done.

DO NOT use starting batteries.
They are not developed for deep discharge.

The size of the battery bank depends on the required cruising speed and motoring distance. Providing your local dealer with information on your boat and your motoring requirements, the optimal size of battery bank will be calculated.

Recharging Batteries

Whether you can install the engine yourself is solely a question of your handyman skills.
If you do not want to make the installation yourself, any boatyard can install it, as it is far easier to install than a diesel inboard.
The engine, including gearing and console weights a fraction of a diesel engine, so it can be easily aligned without the usage of heavy tools, and the electrical components comes pre-wired for easy installation
Note - we recommend using motor mount, to absorb vibrations from the propeller.

On Shore Charging

The size of the shore charger depends on the size of the battery bank and the time available for charging. Your local dealer will help calculate the right charger size upon choosing the size of your battery bank.
Note - if the system chosen is a hybrid solution including a generator, the charger must have Power factor 1, so it can be used for both the generator and shore power.
Note – when ordering the charger, make sure to inform what kind of batteries there will be used, as the programming of the charger differs from lead-acid to gel batteries.

Solar Panels

Solar Panels (Photovoltaic panels) can easily be combined to the system, to charge the batteries by the forces of nature.

Wind Generation

Windmill(s) can easily be combined to the system, to charge the batteries by the forces of nature.

Regeneration by Propeller

By letting the propeller turn while going for a sail, you can charge the batteries by the forces of nature.
Note – to gain a sufficient charge the boat should go a minimum 5 knots while sailing.

Generator

The system can be combined with a generator if the distance that can be achieved by batteries alone does not meet the motoring requirements. The generator can provide power to the electric propulsion system as well as the house loads.

DC to DC Converter

By installing a DC-DC converter you can draw 12 V from the 48 V battery bank for onboard 12 V applications. Hereby you do no longer need to have an additional battery bank and charger onboard for the house loads.

Battery Monitor

By installing a battery monitor you can keep track of your power supply. The battery monitor shows the current consumption and the state of the battery bank (Amps drawing, battery level, how many hours of cruising left at the current speed).

Installation

Whether you can install the engine yourself is solely a question of your handyman skills.
If you do not want to make the installation yourself, any boatyard can install it, as it is far easier to install than a diesel inboard.
The engine, including gearing and console weights a fraction of a diesel engine, so it can be easily aligned without the usage of heavy tools, and the electrical components comes pre-wired for easy installation
