The Lough Ree RNLI crew were tasked to a call-out over the festive period.
On Sunday last, there was a call to assist one person on board a cruiser which developed engine problems on the lake.
The alarm was raised shortly after 1.30pm by the Irish Coast Guard.
The local crew were called to assist a lone boatman on board a cruiser which had called for assistance from St. John's Bay.
Ten minutes later, the Lough Ree RNLI lifeboat 'Tara Scougall' was on the water.
On arrival at the scene just before 2pm, the crew found one person and his dog on board the 30 foot cruiser.
Following an examination of the boat, it was found that an over heating engine was the problem.
The cruiser was taken under tow to Coosan Point where it was tied up safely before 3pm.
