The Achill Yawl Festival is an annual series of races involving traditional Achill yawl sailing boats. The races take place at various locations along Achill Sound, the body of Atlantic water that connects Clew Bay with Blacksod Bay on the west coast of County Mayo. The Achill Yawl is a traditional wooden sailing boat with a solid hull and a single mast. In recent years, partly due to the success of The Achill Yawl Festival, there has been a revival in this traditional vessel. The Achill Yawl Festival runs from July to September each year, with races taking place at weekends and in the evenings (when tides allow). An exciting spectator sport, the races are keenly contested by local teams from the Achill and Mulranny areas.
