The Microtransat Challenge

Sailing across an ocean

We're aiming to be the first fully autonomous sailing vessel to cross the Atlantic successfully and win the Microtransat challenge. Since 2006, no one has succeeded in the autonomous division. SailBuoy won the unmanned division in 2018, but our category requires that no data be sent to the vessel during its voyage.


The challenge covers a wide range of engineering issues: low-power control, sensing reliability and energy autonomy being key focus points. Crucially, all vessels must be under 2.4m, making autonomy an even more difficult task.

With great thanks to our sponsors
