If the association were…
- Key words: AUTONOMOUS SAILBOAT
- A book: La longue route by Bernard Moitessier
- An animal: the dolphin
- A famous person: the love-child of Tabarly and Elon Musk
The sailing robot: architectural choices
After undertaking joint brainstorming and research in small groups, the team made the following choices:
- a very narrow stem, dubbed a “wave-piercer”. This maximizes the vessel’s ability to cut through the waves.
- rigging: this will comprise a rigid sail, which is easy to steer thanks to a rear panel.
- tilted keel, to stop the boat from getting stuck amidst seaweed.
The skills to be combined are wide-ranging and include naval architecture, automation as well as embedded intelligence.

History of the association
The HydroChallenge club follows on from the Hydros Paris-Brest club, set up to compete in the HydroContest.
