Successfully retrofitting your boat with electric propulsion with Weenav
Do you have a motorisation project? Are you considering converting an existing thermal boat to electric or hybrid propulsion? The Weenav design office is here to support you at every stage, with a comprehensive, human, and technical approach.
At Weenav, we believe that the transition to cleaner navigation should not be a constraint, but an opportunity for performance and innovation. Thanks to our expertise in embedded systems and electrical engineering, we offer a structured process in four main phases, from technical analysis to concrete implementation.
1. Analysis of the boat's operation: a personalised energy diagnosis
Everything starts with a thorough understanding of your vessel and your actual needs. We carry out a comprehensive diagnosis based on several pillars:
- A detailed point on the boat's technical documents
- An energy assessment taking into account consumption while sailing and at berth
- An analysis of usage : leisure navigation, transport, tourism, work
- The definition of typical operating days according to the seasons, distances, onboard load, and weather conditions
This preparatory work allows us to identify the constraints to be respected, to lay the foundations of the future propulsion system, and to optimise autonomy while respecting your operational objectives.
2. Technical design & recommendations: a system tailored for your project
Based on the analysis, our design office develops a custom technical solution. At this stage, our team of engineers sizes the necessary equipment (motor, batteries, controllers, chargers, etc.) based on:
- The architecture of the boat
- The desired autonomy
- Regulatory requirements
- And operational specifics (type of navigation, frequency, duration, environment)
We also carry out a site study to ensure the optimal integration of equipment on board. Finally, we anticipate the upcoming administrative and regulatory steps and define a roadmap for the smooth progress of the project.
3. Drafting the regulatory file: heading for compliance
Navigating legally is imperative, especially on river and maritime basins subject to strict standards. That is why we take care of the preparation of the regulatory file essential:
- Drafting the technical file
- Prior declaration of commencement of work
- Identification of necessary modifications (after discussions with the relevant authorities)
- Monitoring of discussions with the instructing service
This step allows for obtaining the necessary navigation permits, with complete peace of mind.
4. Custom quote and site coordination: from project to reality
Final step: we move on to implementation. Our team establishes a consultation file intended for the selected service providers to intervene on the site (electricians, shipyards, suppliers). We assist you in:
- The choice of technical partners
- The analysis of the quotes proposed
- The organisation of the site
- And the management of the schedule of the works
The objective? For your boat to set sail in the best conditions, respecting the budget, the timeline, and the applicable standards.
