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.

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.

CO2 emissions come from the combustion of fossil fuels and are one of the main causes of climate change. By opting for electric motors for boats, it is possible to reduce or even eliminate CO2 emissions, thus contributing to the fight against global warming.

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.

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.

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.

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 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.

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.

The Garmin GPSMAP is an essential navigation tool, available in various sizes, including 9, 12, and 16 inches. At Weenav, these screens are integrated into the energy management and navigation system for electric motors. Weenav also offers the customization of these screens, with the possibility of having two, in order to facilitate the management of navigation and embedded systems. The touch interface makes it possible to monitor the battery status in real time, to control the boat, and to access detailed maps, while improving the user experience while browsing.

Grants are financial aid granted by the State, local authorities or private institutions to encourage projects that are innovative, ecological or in line with sustainable development goals. In the navigation sector, grants can help finance the installation of electric or hybrid motors, the modernization of propulsion systems or even initiatives to reduce CO2 emissions. These grants are often decisive in reducing the initial cost of new technologies and promoting their adoption.

A hybrid propulsion system combines an electric motor and a combustion engine, offering flexibility between energy sources. It makes it possible to switch between electricity for navigation phases at low speed or in protected areas, and the combustion engine for longer trips requiring greater autonomy. This type of system is often chosen for reasons of energy efficiency and emission reduction.

The IP67 code is a degree of protection defined by the IEC 60529 standard, which assesses the degree of protection of equipment against solids and liquids. It is correct that the number 6 indicates complete dust tightness, ensuring that no dust particles can penetrate the equipment. The number 7, on the other hand, certifies that the equipment can withstand temporary immersion in water, generally up to a depth of 1 meter for 30 minutes. This IP67 certification is therefore ideal for marine electric motors, as it guarantees protection against humidity, splashes, and accidental immersion in difficult maritime environments. In addition, it is important to note that the IP code does not guarantee protection against water under high pressure (such as powerful water jets), which would be covered by a higher degree of protection, such as IP68, which provides better protection against prolonged immersions at greater depths. For marine environments, where engines are often exposed to humidity, salt water, and extreme conditions, an IP67 certified motor is particularly well suited, guaranteeing increased durability under these conditions.
