In December 1959 the East coast of Scotland was experiencing one of the worst storms in recorded history. Given its location the North Carr was particularly vulnerable. According to the report of G Rosie the Senior Master on board at the time ".... at 02.02 am on Tuesday 8th December whilst riding out a gale of Southeast wind and very heavy sea the anchor cable parted". As a result the North Carr began to drift. At 2.20am the Fifeness Coastguard noticed North Carr moving off station. The nearest lifeboat stationed at Anstruther, was alerted but was not given permission to launch and this was the same for the lifeboats at Dunbar and Arbroath. At 2.50am the crew of the North Carr managed to deploy the port emergency anchor and bring the vessel to a halt, but their situation remained perilous. At about the same time the Broughty Ferry Life boat the Mona was given Permission to launch in order to come to the aid of the North Carr.
The Mona launched at 03.13 for the 30th time. At 03.36 the Fifeness Coastguard made radio contact with the Mona. At 04.06 in a radio exchange wit Fifeness Coastguard the Mona gave her position as being abreast of the Abertay Light ship. At 04.48 Carnoustie Coastguard radioed the Mona to ask if she had seen the latest flare launched by the crew of the North Carr. The Mona replied that they had seen the flare and stated "we have reached the bar". The Mona was not heard from again. The vessel was found on the morning of 9th December washed up on Buddon Sands near Carnoustie with 8 crew still inside. The body of the 9th crew member was never found.
