Microtransat Challenge

The Microtransat Challenge is a transatlantic race for autonomous boats, aiming to stimulate the development of autonomous boats through friendly competition. Running for over a decade, there is a rich and varied history of teams that have taken part.

Related Competitions

A spin off competition, the World Robotic Sailing Championships (WRSC) was created in 2008. This consists of a series of short races and other challenges for autonomous boats. Attached to the WRSC is the International Robotic Sailing Conference (IRSC), which allows researchers in the area a chance to meet up and discuss the scientific issues related to robotic sailing.

The SailBot competition is another competition for robotic sailing boats, which has taken place in North America since 2006. This is targeted at student teams and focuses on high performance short distance racing.

Microtransat teams are encouraged to attend a WRSC or SailBot event to meet other teams, exchange ideas and test out their boats.
