The limits of the Irish Marine Search and Rescue Region (IMSRR) correspond with those of the Irish Flight Information Region (FIR) - approximately 200 miles off the West Coast, 30 miles off the South Coast and dividing the Irish Sea.
The Irish Coast Guard's Search and Rescue region has been divided into three zones each under the coordination of a particular Coast Guard Coordination Centre. They are the Dublin, Malin and Valentia Divisions.
