Welcome to the World Robotic Sailing Championship and International Robotic Sailing Conference (WRSC/IRSC). The WRSC is a competition open to fully autonomous and unmanned sailing boats up to 4m in length. This year's WRSC/IRSC is being held in Cardiff, Wales, UK. It is the fifth edition of the regatta, with previous events held in Austria (2008), Portugal (2009), Canada (2010), and Germany (2011). This year competitons in four classes are planned: the Microtransat class with boats of up to 4 m, the SailBot class with boats of up to 2 m, a One Design MicroMagic class with boat of 0.53 m in length, and the Hacker Challenge. The latter will be held for the first time and requires competitors to build boats during the course of the week for a short race on the final day.

The accompanying International Robotic Sailing Conference (IRSC) provides an ideal venue to discuss the broad range of scientific problems involved in the desgin and development of autonomous sailboats.
