Lifeboats paged at 14:07 by Belfast Coastguard to reports of a 5 metre Speed boat which had broken down in the Antrim bay.
Lifeboats launched and located the casualty vessel 2 miles south of Antrim.
Once located, the vessel was checked for any damage and a tow line was connected. The vessel was towed to Antrim Marina.
Lifeboats returned to base, washed, refuelled and ready for our next tasking.
