sobriety and reuse
This circular approach aligns with low-tech ingenuity and DIY adaptability in preparing the boat for an unprecedented route. It is the opportunity for a powerful narrative: a human and athletic adventure with a minimal environmental footprint that embodies circular values!

The ocean
By analyzing satellite imagery over recent summers and ice condition trends, I confirmed the feasibility. A determined crew equipped with a perfectly adapted sailboat can navigate both the Northeast Passage, north of Eurasia, and the Northwest Passage, north of America. In doing so, I will complete a world circumnavigation via the shortest route. It is now up to me to deliver the practical proof!
Accomplishing an athletic and technical performance
October 2024 - February 2025
Initialization & Planning
- Choice and acquisition of the boat
- Assembly of the crew
- Theoretical study and routing simulations based on 4 years of archive weather & satellite data
- Design of technical solutions required for this navigation
- Management of administrative procedures (authorizations, visas, clearances)
February 2025 - July 2026
Technical refit on the boat
- Conveyance of the sailboat to Lorient and refit: complete structural check, reliability enhancement, and weight reduction.
- Preparation and specific adaptation of the boat: maneuver simplification, sail area expansion, structural reinforcements, pedal drive, safety systems, etc.
August 2026 - June 2027
Training & boat optimizations
- Sea trials, iterations and validations
- Training, team coaching and preparation.
July - September 2027
Expedition
- Departure in July 2027
- Arrival in September 2027
October 2027 - May 2028
Post-expedition
- Promotion of the expedition through a series of events
- Refit and exhibition of the boat in Lorient and in Paris, on the Seine.
