Boat Club - Roscommon Sports Partnership - The local boat club was established in the 1960s. An annual regatta was held in July. It consisted of single, double sculls at underage and senior levels. The route would run from the edge of the bay at Cope wall to point of Cruit and back. Classes were run to build boats in some years during the winter. Seamus Kilroy from Strokestown a Vocational School Teacher was one of the instructors. It took from September to March to make. The materials cost 100 Irish pounds. In the shed of the railway station Des Murphy, James Kelly, Michael Mugan, Pat Lyons and John Devaney gathered. When the boats were completed they were lined up outside the local church to be blessed.
The decline of the Boat Club occurred in the 1980s due to emigration.
