40 to 45 feet, less than 12 tons monohull sailboats

Ideal to cruise with the family, it has all kinds of comfort on board, electrical self sufficiency is an important point if you do not want to stop every evening in crowded ports in summer.

We recommend the following solutions for the electric motors and the autonomous production of green energy on your boat :

• Electric or hybrid motor solutions
• Solar panels
• Power generators

ELECTRIC OR HYBRID MOTOR FOR SAILBOATS

OCEANVOLT Sail Drive 15 kW or SERVOPROP electric motor

OCEANVOLT offers 2 types of sail drive from 10 to 15 kW. The standard SD model and SERVOPROP. The latter is equipped with a variable-pitch propeller that improves propulsion power by 30% and the regeneration by 300%.

From 39,000 euros HT (SD) and 46,000 euros HT (SERVOPROP) with a 19 kWh battery pack and chargers.
Not including installation and transport.

photovoltaic production

Technological advances in terms of solar panels on boats make them almost essential nowadays, whether it is to maintain the charge of the batteries during absences, without having to moor the boat to the dock, or to spread the ever-increasing consumption on board and supply power to the batteries of the electric motor propulsion.

For a boat that is less than 40 to 45 feet, the installation of fixed panels on the davit is ideal, it can be combined with flexible solar panels to be placed on the roof or the bimini.

We offer SUNBEAM products, a Swedish company that produces the strongest and most efficient flexible panels on the market.

25% high efficiency cells and Rear Contact Technology
Anti-slip coating trampling resistant
Optimized coating for shaded areas
5-year warranty

GENERATOR FOR A SAILBOAT

Take advantage of the space saved with the installation of an electric motor to give yourself the comfort of a generator.

We have selected the sets from the brand Fischer Panda because they are compact, silent and they can be easily integrated into a 48 volts electric motorization system.

The set could therefore supply the batteries and the motor. We recommend the AGT DC with a power of 3 to 25 KW.

Almost unlimited autonomy
Comfortable electrical equipment
Low noise thanks to its cocoon
Low Weight
(Generator + electric motor + batteries) equivalent to a Diesel engine.

The electric motor is clean, silent, powerful and what is even better: self sufficient. It is a dream to use it in difficult situations, because you only have to push the handle and you are ready to go !
