The Aberdonia is a British pre-war motor yacht moored at Chelsea Harbour.

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.

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.

[1][2] Aberdonia was nearly destroyed during her naval service by a downed German bomber whose pilot attempted to guide his falling plane into allied ships.
