Welcome to our glossary. You will find clear and concise definitions of essential terms related to our business. We want to offer you a quick and accessible understanding of the key concepts related to electric motorization for boats.

Alignment

A method of navigation consisting of sighting two fixed points in line with each other to determine a course.

Anchor

An anchor is a metal device used to hold a boat in place by catching on the seabed or riverbed.

Anchoring

The act of stabilising a boat on the water using an anchor or buoy; also refers to the place where the anchor is dropped.

Autonomy

The autonomy of a boat refers to the distance it can travel without recharging batteries or without refueling. With Weenav electric motors, the autonomy varies according to the configuration of the batteries and the type of navigation. For example, a boat equipped with the KRONOS engine can have a range of up to 100 nm. This autonomy is crucial for long trips, and Weenav offers real-time energy management through integrated systems, making it possible to maximize energy efficiency during trips.

Autopilot

Autopilot is a system that allows a course to be maintained without manual intervention.

Barge

Flat-bottomed vessel, often used on rivers for transport or work.

Battery capacity (kWh)

The capacity of a battery, expressed in kilowatt hours (kWh), indicates the total amount of energy it can store.

BMS (Battery Management System)

The BMS is the electronic system responsible for monitoring, protecting and optimising a boat's electric batteries. In particular, it controls the temperature, voltage and state of charge of each cell to ensure safe use and maximum battery life. At Weenav, the BMS is integrated to guarantee reliable and efficient energy management.

Boom

The boom is a horizontal bar attached to the bottom of a sailing boat's main sail. It is used to control the orientation of the sail.

Bow

The front part of the boat, which cuts through the water.

Buoy

Floating device used to mark an area, indicate danger or for mooring.

Cap

Heading represents the direction a boat must follow to reach a destination, expressed in degrees from north (0° to 360°). Weenav's navigation systems, coupled with GPSMAP screens and electric motors like the KRONOS, allow users to track and adjust course in real time, ensuring accurate and optimized navigation to save energy while maintaining safety, even in complex environments.

Carbon footprint

The carbon footprint represents the total quantity of greenhouse gases emitted directly or indirectly by an activity or product, often expressed in CO2 equivalent. Reducing the carbon footprint in navigation involves opting for electric motors that limit CO2 emissions compared to traditional internal combustion engines.

Catamaran

A catamaran is a boat with two parallel hulls. This design offers better stability, low energy consumption and comfortable sailing.

CE standards

CE standards (European Conformity) ensure that products, especially electric motors, meet European health, safety and environmental requirements. Applying the CE mark to a product indicates that it complies with European Union regulations, making it possible to sell it within the European Economic Area. The Weenav system fully complies with these standards, ensuring that their solutions meet the strict requirements for safety and environmental protection.

Réglementations

Channel

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

What is a retrofit?

The transformation of a thermal vehicle (car, boat, bus...) into an electric or hybrid vehicle, also called retrofit, involves the replacement of the combustion engine by an electric motor or the integration of a hybrid system. This includes installing batteries, an electric motor, controllers, and other components needed to provide electric propulsion. This process reduces greenhouse gas emissions while increasing the vehicle's fuel efficiency.

What is the energy consumption of an electric motor?

Our electric motors range from 50 kW to 400 kW. At low speeds, consumption can drop to 10 kW, which ensures a minimum autonomy of 10 hours on any boat, depending on specific sailing conditions and battery capacity.

What is the maintenance difference between electric and thermal motors?

Electric motors require less maintenance than internal combustion engines due to their mechanical simplicity (fewer moving parts) and the absence of certain critical components such as oil filters, spark plugs, etc. Electric motor maintenance focuses primarily on maintaining electronic systems, batteries, and the motors themselves, with less need for mechanical adjustments or frequent replacement of parts.

What advanced technologies are used in electric motors?

The advanced technologies used in electric motors are high-performance permanent magnets, vector control and oriented flow controls (FOC), advanced sensors, variable frequency drive (VFD), improved cooling, monitoring and self-diagnosis systems, modeling and simulation, modeling and simulation, modeling and simulation, compact optimized coil technology, compact optimized coil technology, optimized compact coil technology, cooling at the core of the rotor optimizing efficiency as well as the development of the dashboard with a connection of information between them.

What are the ecological advantages of electric motors?

Electric motors offer undeniable ecological advantages by reducing local emissions of exhaust gases and particulates, by reducing the carbon footprint through the use of renewable electricity, and by minimizing noise pollution, thus maintaining marine ecosystems. Their design with fewer moving parts and simplified maintenance also contributes to reducing the overall environmental impact while meeting strict environmental standards.
