The lifeboat crew located the vessel, which had suffered engine failure, three miles east of Glenarm Marina.
Two people on board the boat were transferred to the lifeboat before the vessel was taken in tow to Glenarm.
On arrival, the lifeboat transferred a crew member to the yacht and made good a towline. Before the tow commenced the yacht's integrity was checked.
After successfully towing the vessel into deep water, another check for leaks was made before the yacht and its crew were happy to make their own way to East Ferry.
