The lifeboat, under the command of deputy coxswain Sean Bawn O’Sullivan, was launched within minutes and located the vessel at anchor about one hour later.
With light winds and a 3-4m swell, RNLI volunteers passed a tow rope to the crew onboard, and the lifeboat took the vessel under tow to Castletownbere.
When off Crow Head some time later, the tow rope broke and had to be reattached. The tow was then completed without further difficulty.
The vessel was berthed alongside the pier in Castletownbere at 2.30am yesterday morning (Saturday 17 December).
