Launched at Caledon Shipbuilding in Dundee, Scotland on July 2, 1924 the 1,101 ton freighter Rydal Force was used as a coastal freighter for the West Coast Shipping Company for her whole career. That career came to a deadly end on April 24, 1940 when she hit a mile laid by German aircraft off the Gull light vessel at the River Thames. Eleven of her crew were lost in the sinking, the wreck is still where it sank all those years ago.
