The female visitor to Inis Mór had sustained a suspected fractured leg while out sightseeing, Aran Islands RNLI said.
The casualty was transferred safely aboard the Severn class lifeboat David Kirkaldy under coxswain Tommy Dirrane and a full crew, and was brought to the waiting ambulance at Rossaveal Harbour.
Dirrane said later: “The volunteer crew members train regularly to maintain their quick response time and that can make all the difference to the casualty you are going to help. We would like to wish the casualty a speedy recovery.”
Elsewhere on Saturday, Rosslare Harbour RNLI volunteers were called to assist a small yacht with two onboard in difficulty off Cahore Point off the North Wexford coast.
Tangled in a lobster pot line and unable to sail in the freshening south westerly wind, the crew called the Irish Coast Guard for assistance, according to the RNLI.
Rosslare Harbour RNLI volunteers launched their all-weather lifeboat and reached the yacht in a short time.
Lifeboat volunteers reached the yacht in short order and set up a tow line to bring it close to Cahore Harbour, where the Cahore inshore rescue boat took over due to the shallow water.
Rosslare Harbour RNLI coxswain Eamonn O’Rourke said: “I would like to commend our volunteer crew who worked hard to attach a tow to the yacht in challenging conditions. We were glad to see the vulnerable yacht and her crew safe.”
