• Efficient, compact and robust brushless permanent magnet
motor for silent and carefree boating.
• Closed cooling system that combines the lubrication of
mechanics and motor cooling. The sail drive acts as a heat
exchanger.
• Sleek hydrodynamic profile on leg provides minimal
resistance in all sailing conditions.
• 1.93:1 reduction with custom made bevel gear for efficient
propulsion.
• Integrated controller for compact size and easy plug & play
installation.
• Flexible rubber mounting to the hull ensures a smooth
vibration free and silent ride as well as easy installation.
• Large propeller diameter for high propulsion efficiency.

Regenerating is achieved by letting the propeller turn while sailing and
using the motor as a dynamo, thus reducing the weight and cost of the
battery bank.

Electric Inboard Drive System
Electric motor with built-in regenerative function!
Models available for sailing yachts from 16 feet
to 45 feet (up to 10 tons).
Power range: 5 kW to 13 kW (can replace
combustion engines up to 40 HP).
The average required power is 1.5 kW to 2 kW
for each ton.
The motors are reversible and can regenerate
the batteries under sails (the water drag on the
propeller drives the gear shaft).
Battery regeneration makes it possible to
reduce the size of the battery bank while
providing sufficient energy.
Electric drive system can be installed as initial
equipment or as retrofit.
It is very easy to replace a combustion engine by an electric drive system:
»
Acoustic nuisance and
vibrations.
Warm up delay.
Inevitable pollution: oil / fuel
spillages, vapor relief).
Not easy to handle.
Complex installation.
Heavy maintenance: filters,
belts, oil changes…

The engine compartment
has been cleaned. The shaft
and motor bracket are kept
in place.
With an electric motor, the
system is virtually silent.
The power kicks in immediately,
making harbor maneuvering
easier and more accurate.
The environment is free of oil
spills, smell of diesel and
exhaust fumes.
Maintenance consists only in
replacing the brushes and the
gear belt.

Electric Propulsion Systems
Hybrid Propulsion
Operating principle:
Install a compact, low power generator with automatic start-up, to provide
complete autonomy to the electric propulsion system.
The generator receives continuous up-to-date information on the battery bank
and it automatically starts whenever the low voltage set point is reached.
The objective is to optimize the global efficiency of the propulsion system in
order to reduce energy consumption and to pollute as little as possible.
The generator works at constant speed and nominal power for an enhanced
efficiency.
Benefits:
- Autonomy (generator).
- Low maintenance.
- Power and torque available at any time.
- Battery capacity available for other equipments.

Lithium ion battery can be charged in a very short time
thus optimizing the generator operation and minimizing
the system weight and required space. Lithium ion
batteries can deliver high currents without capacity
losses which make them very attractive for an electric
propulsion system. Along with a high capacity battery
charger, a system using this battery technology is almost
completely autonomous.
