Lough Neagh Rescue was called last Friday evening to a 24ft cruiser that had lost power.
The vessel was located about 1.5 nautical miles to the east of Ballyronan on the west side of Lough Neagh.
Lifeboats were launched and located the vessel with two people on both of whom were safe and well. A towline was secured, and the vessel towed into Ballyronan Marina, where it was safely moored to the jetty.
The lifeboats returned to base, were cleaned, refuelled and are ready for the next tasking.
Lough Neagh Rescue is a Limited Company and a registered Charity. It is made up of 60 highly trained volunteers, four lifeboats, two vans and an off-road jeep, operating on the largest lake by area in the British Isles with a surface area of 151 square miles.
