Built by Phillip & Son Dartmouth, Devon for Trinity House London in 1938 (Yard Number 848) she was launched on 1 November 1938 and handed over to Trinity House on 27 January 1939.
She served as a light vessel on various stations from 1939 to 2004 apart from during WWII when she acted as a mine watching vessel in the River Thames.
Her stats are below.
Displacement: 519 tons (fully loaded)
Since 2004 she has been in private hands and I believe is currently used as a photographic studio.
