Falmouth Inshore Lifeboat was called away from Helford Village Regatta on Saturday to help two people whose sailing dinghy had capsized in the Carrick Roads.
Falmouth Coastguard contacted the RNLI just after 3pm, after two sailors who had hired a wayfarer from Loe Beach before capsizing near the Pill Buoy, where its mast had become stuck in the mud.
The lifeboat arrived on the scene at around 3.15pm, to find that the harbour master's launch Carrick 2 had been on patrol and had managed to recover the two casualties from the water.
A lifeboat spokesperson said: "The inshore lifeboat crew confirmed that the casualties did not need any medical attention but were just cold and wet, so they were transferred to the inshore lifeboat and landed at Loe Beach.
"The inshore lifeboat then helped the owner of the capsized dinghy to right the boat and escorted it back to Loe Beach."
