The Lough Derg RNLI lifeboat assisted nine people on Sunday morning after their 55ft vessel ran aground near Drominagh Co Tipperary.
The alarm was raised at around 11.30am when the watch officers at the Irish Coast Guard marine rescue sub centre on Valentia Island in Kerry were alerted to the incident.
They received a report of a cruiser with a total of nine people on board having run onto rocks on the norther end of the lake. The Coast Guard immediately contacted the Lough Derg RNLI lifeboat by radio, knowing they were on the water at the time.
The Dromineer based volunteer crew had been been taking part in their routine Sunday morning training exercises when they were alerted.
They were requested to make their way to the scene so the lifeboat crew was able to break away from training and make its way to the area where it arrived about 15 minutes later.
On reaching the casualty vessel, lifeboat crew members set about determining that all casualties were safe and well and also carried out an inspection to see whether boat had been damaged. The crew then attached a tow rope and pulled the boat off the rocks and into safer and deeper water.
Crew members Dom Sharkey, Keith Brennan, Doireann Kennedy and new recruit Tom Hayes were onboard the inshore lifeboat at the time.
Lough Derg RNLI Helm Dom Sharkey said: “We were delighted to be able to assist those on the cruiser this morning. We would remind anyone planning a trip on the lake to make sure you stay between the markers to avoid shallow waters on the lake. Should you get into difficulty call 999 or 112 and ask for the Coast Guard.”
Earlier in the day, whilst engaged in training exercises near Droman Harbour, the volunteer crew noticed a sunken boat. The crew inspected the vessel to ensure there were no casualties on board and reported the details to the Irish Coast Guard.
