A defined and secure navigation channel allowing vessels to navigate while avoiding shallow areas.

A charge cycle corresponds to a complete charge followed by a complete discharge of a battery. The service life of a battery is often expressed in terms of the number of cycles. The batteries used with Weenav motors are designed to withstand a large number of cycles in order to guarantee optimal longevity.

Navigation effectuée près des côtes, souvent d'un port à l'autre, par opposition aux voyages en haute mer.

Area of the boat where the helm and navigation controls are located. Steering area.

The Connect 50 is a device from Garmin's EmpirBus range, which specializes in digital switching systems for marine applications. Designed to manage and control electrical circuits on board boats, this module is part of a family of devices that centralize and automate electrical functions, such as lighting, pumps, or actuators. The Connect 50 is characterized by its compact design, ideal for smaller or less complex installations, while offering accurate management of energy consumption per channel. It can also be integrated into larger systems and communicates via the NMEA 2000® network, a popular standard in marine electronics. Thanks to its robustness and its multiple functionalities, it makes it possible to effectively control various electrical devices on board, while optimizing the safety and performance of the boat's systems.

Continuous torque is the force that the engine can deliver continuously, while maximum torque corresponds to the force delivered instantaneously at start-up.

Manoeuvre consisting of approaching a quay or pontoon in order to moor there.

The minimum depth of water required for a boat to float without touching the bottom.

ESTRIN (European Standard Technical Requirements for Inland Navigation Vessels) is a European standard that establishes the technical requirements for the construction, equipment and maintenance of inland navigation vessels, such as barges and other river boats. This standard aims to guarantee the safety and efficiency of ships, while promoting the protection of the environment. Weenav offers electric and hybrid propulsion solutions that fully meet the requirements of ESTRIN, thus ensuring that their engines comply with safety, performance and sustainability standards, while reducing the environmental impact of inland navigation boats.

Being eco-responsible consists in adopting practices that minimize environmental impact and promote sustainable development. In the shipping sector, this may include the use of electric motors, the reduction of polluting emissions, and the adoption of renewable energy solutions. An eco-responsible boat favors technologies that preserve the environment while improving energy efficiency.

The planking is the outer covering of a boat's hull (wood, aluminium, steel, composite, etc.).

The efficiency of an electric motor measures its efficiency in transforming electrical energy into mechanical energy to propel a boat. Unlike internal combustion engines, electric motors generally have an efficiency greater than 90%, with those from Weenav reaching up to 97%. This exceptional performance is due to an optimized design that minimizes energy losses in the form of heat. This high efficiency results in increased performance, reduced energy consumption, and improved durability, making Weenav engines particularly suited to the requirements of modern maritime solutions.

Device for signalling an exact position to rescue services in the event of an emergency at sea.

Energy efficiency measures the amount of energy consumed for a given activity, comparing the resources used with the results obtained. In the field of navigation, improving energy efficiency involves the use of engines and propulsion systems that consume less energy while offering optimal performance, such as electric motors, which transform energy into movement better than internal combustion engines.

The energy saving certificate (CEE) is a device put in place by several governments to encourage the reduction of energy consumption. Businesses and individuals who carry out works or installations that reduce energy consumption, such as the installation of efficient electric motors, can obtain this certificate, often accompanied by subsidies or tax incentives.

The term GATE refers to the Energy Transition Support Group, a support system for river transporters in the context of the energy transition. GATE helps these operators to green their fleet, in particular by facilitating the process of re-motorizing existing boats with electric or hybrid solutions. The program offers support at each stage of the project, from energy analysis to implementation, in collaboration with a Project Management Assistant (AMO). This system is financed by public institutions as part of the CEE ReMoVe program, which aims to improve the energy and environmental efficiency of transport fleets.
