The Lough Derg RNLI lifeboat was called out to assist two people after their 35-ft cruiser suffered engine failure close to Mountshannon on the Clare shore.
The Dromineer based lifeboat was launched at lunchtime in south westerly, force 4/5 winds and poor visibility.
The lifeboat reached the scene within minutes and crew quickly assessed the situation. Two crew members transferred to the casualty vessel and established that those on board were safe and well and were wearing lifejackets.
With their boat drifting without power, the occupants were quick to drop anchor to prevent them drifting them into further danger.
The RNLI crew members checked the cruiser for any damage before setting up a tow. The lifeboat brought the vessel to Mountshannon where they transferred to an alongside tow to transport the cruiser into the harbour safely. The vessel was safely tied up alongside at 1.30pm.
Lifeboat Operations Manager Liam Maloney advised afterwards: “Before setting out on the lake, make sure your boat is serviced and has sufficient fuel for your journey. If you get into difficulty, call 999 or 112 and ask for the Coast Guard.”
