The propulsion systems of large vessel are generally dimensioned for cruising at sustained speeds between 9 and 15 knots.
However, engine performance and wear and tear deteriorate outside the optimal operating range. LEEN-TRIMARANS innovates on this point by offering an auxiliary engine for low speeds.
LEEN-TRIMARANS organises the propulsion of its trimarans around 3 engines, for greater efficiency and safety:
- 1 main engine in the central hull
- 2 electric auxiliary motors in the side floats

A professional solution for system durability
Mechanically, the major advantage of electric motors over internal combustion engines is their very high torque at low speed.
LEEN-TRIMARANS optimises its efficiency with adapted propulsion systems, resulting in less wear, less maintenance and more efficiency.

An environmentally friendly choice:
With suitable solar panel equipment, the LEEN can be propelled with 100% solar-generated electricity for short periods and at low speed. Hybrid propulsion reduces the discharge of hydrocarbons into the sea.

Increased navigation comfort and flexibility
Hybrid propulsion means less noise pollution and makes it possible to access protected areas in full electric mode (with up to 2 hours of autonomy without recharging the batteries).
