The sole occupant of the 33ft motorboat was a Dutch man who was travelling from Dun Laoghaire to Cork when his vessel lost power and he ran into difficulty.
The lifeboat crew responded to the call at 1.55pm and were quickly on scene to establish a tow.
Conditions were good for the journey back to land; there was a slight haze but the sea was calm.
The lifeboat crew towed the vessel back to the Fisherman’s Wall in Rosslare Harbour and the tourist was welcomed ashore.
Commenting on the callout, Rosslare Harbour RNLI lifeboat operations manager Dave Maloney said: “It was perfect conditions for a callout. As the man was travelling on his own we put one of our lifeboat crew onboard to help establish the tow and to check everything was okay.
“Thankfully it was nothing too serious and we were able to bring him safely to Rosslare where he could get his vessel seen to and hopefully continue on with his journey.”
The RNLI and Irish Coast Guard issued a joint call earlier this week for people to stay safe on or near the water this May Bank Holiday weekend, as previously reported on Afloat.ie.
