Several boats on St Mary's escaped their moorings in the early hours of Monday amid high waves and winds of around 36mph.
The St Mary's lifeboat crew were paged at 2.45am when a yacht in the harbour issued a Mayday having broken adrift and then wrapped a mooring around its propeller. The crew used the small inflatable boarding boat to get to the yacht, which had two people on board.
They managed to secure the vessel but another escaped its mooring lines at the same time and went ashore in Porthmellon. It was later reported: "Pete [Hicks] called the Harbour Master and the staff then assisted the lifeboat crew with Pegasus to tow this second yacht off. Weather in the harbour was fresh West force 7 and low tide so caused issues with other vessels through the early hours also."
The lifeboat was also called out shortly after 9pm on Sunday after a yacht came loose from its moorings and ran aground on rocks between Porthmellon and Sharks Pit (pictured). The crew were unable to refloat the vessel and it is thought it will remain aground until it can be floated on the next Spring tides in around two weeks' time.
