The lifeboat launched at 1.46 pm at the request of Valentia Coast Guard with volunteer crew members Dom Sharkey, Owen Cavanagh and Christian Parker and helmed by Eleanor Hooker.
Weather conditions were calm with force 2 winds and good visibility.
The lifeboat reached the casualty vessel and established that the people on board were safe and well. The lifeboat took soundings of depth on approach as the cruiser was high on a rocky shoal.
A crew member transferred to the vessel and checked it was not holed and the rudder and drives were all in good working order. With the crew member still aboard they set up a tow and took the boat off the rocks and into safe waters. The RNLI volunteer showed safe water and markers on the chart before the cruiser continued its journey without further assistance from the lifeboat.
Deputy Launching Authority, Brendan O’Brien said ‘We advise people using the lake to anticipate each marker on their route and study their charts when passage planning and to enjoy Lough Derg’
