World War II service
Aberdonia was requisitioned to work as a patrol boat in the Royal Navy attached to HMS Fervant in 1940, at which time she was renamed Navigator. She participated in the evacuation of Allied troops at Dunkirk. The yacht is believed to have made four trips to the shore to take on men cut off by the German army. She worked with the minesweepers and ferried sealed orders between the Admiralty and convoys lying off Shoeburyness and Deal.
