The Seren Y Mor is an Ex Liverpool Class Single Crew Lifeboat, formally named the Frank and William Oates.
The Frank and William Oates was originally stationed at Eyemouth from 11.03.1937 to 12.12.1951. During her time in Eyemouth, she launched 17 times and saved a total of 9 lives.
She was later sold in 1964, renamed The Seren Y Mor (Star of the Sea) and came to Tenby. From 1964, for 40 years, she carried passengers back and forth Caldey Island. She was then sold again to a local fisherman to become a Mackerel Fishing Boat. For many years Seren Y Mor has done daily Mackerel trips from early April to mid September.
