The boat
that sails
itself.

NAIR Sailing is ETH Zürich's student engineering team designing a fully autonomous sailboat to cross the Atlantic.

4,000 kilometres of open ocean

The Microtransat Challenge is the longest-running autonomous sailing competition in the world — a transatlantic race for uncrewed vessels under 2.4 metres long. Since 2010, no team has completed the east-to-west crossing. We are out to change that.

We are building a 2.4-metre sailing platform that navigates, trims its own sails, and routes around weather — running the entire autonomy stack on less than 20 W of continuous power.

Portugal to the Caribbean. The long way.

The Microtransat course runs from a line off the coast of Portugal to a line stretching from Martinique to Barbuda. Boats must cross the entire Atlantic without intervention.

Built for sixty days alone.

Every subsystem onboard is chosen for reliability above all other qualities: the ability to fail gracefully two thousand kilometres from the nearest human. Mechanical simplicity, redundant compute, and zero moving parts where we could help it.

Cross-discipline
by design.

We are commited to building the most reliable boat we can, and that means building a team with the widest possible range of skills and perspectives.
