At 5.30pm on Saturday April 15, Valentia Coast Guard requested Lough Derg RNLI Lifeboat to launch to assist 10 people after their 40ft cruiser ran aground by the Scilly Islands on Lough Derg.
Valentia Coast Guard informed the lifeboat that the Killaloe Coast Guard RIB had also launched to assist.
At 5.45pm, the lifeboat launched with helm Eleanor Hooker, Ger Egan, and Keith Brennan on board. Winds was south-westerly, Force 4, gusting 5. Visibility was good. Valentia Coast Guard informed the lifeboat that the Killaloe Coast Guard RIB had also launched to assist.
The lifeboat arrived on scene at 6pm, the casualty vessel was aground north of the Scilly Islands. The Killaloe Coast Guard commenced an anchor and veering down to the casualty vessel.
All 10 people were unharmed and wearing their lifejackets.
As the vessel was high on a rocky shelf, it was decided to transfer all casualties to Mountshannon Harbour, five on board Lough Derg RNLI lifeboat and five on board the Killaloe Coast Guard RIB, and where the land mobile Coast Guard unit was waiting to receive the casualties.
Both the lifeboat and the Coast Guard RIB returned to the casualty vessel. Once satisfied that the cruiser was not holed, she was safely taken off the rock shelf and towed by the Killaloe Coast Guard boat to Mountshannon.
Peter Kennedy, deputy launching authority at Lough Derg RNLI Lifeboat, advised boat users to "bring charts with you and identify the areas close to shore and islands marked as not navigable, particularly as water levels are relatively low in the lake at the moment".
