The Irish Coast Guard has contracted five medium-lift Sikorsky Search and Rescue helicopters deployed at bases in Dublin, Waterford, Shannon and Sligo. The helicopters are designated to be in the air from initial notification in 15 minutes during daylight hours and 45 at night. We hope that we will never need to call on them but it is reassuring to know that in an emergency they are on standby 24 hours per day.
