Garroo Clagh ("Rugged Boulder") is a location on the coast north of Fleshwick in the west of the Isle of Man. A landslide at this site swamped a fleet of Dalby fishing boats that were sheltering there on a Sunday night, with only one fisherman surviving. The disaster, believed to have occurred more than a century before 1809, was regarded as divine punishment for Sunday fishing and is counted among the three great losses of the Peel herring fleet.
