Workington RNLI was called out by Belfast CGOC at 10.24am after reports that a boat was in distress at Allonby Bay, off Crosscanonby.
The yacht, which had two men, two women and a baby on board, was taking on water.
Workington RNLI launched the Shannon class Dorothy May White.
A spokesman for Workington RNLI said: “By the time of our arrival, the Mareel Old Rose, which services the Robin Rigg windfarm and Maryport fishing vessel Silverfern were alongside. Maryport Inshore Rescue, was also in attendance.
“The two women and the baby had been transferred to the Mareel Old Rose and were subsequently transferred to the Dorothy May White.
“Workington RNLI volunteers boarded the distressed yacht and began pumping out water.
“The yacht was towed safely to Maryport Marina, where Maryport Coastguard Rescue Team and Whitehaven Coastguard Rescue Team were in attendance.
“All persons on board the stricken vessel were safe and well. Our thanks to all our colleagues and the crews of the Mareel Old Rose and Silverfern for their help.”
The Dorothy May White returned to the boathouse at around noon.
