Kiloran was an armed yacht, and I have managed to unearth this image, which seems on the face of it to be
Kiloran functioning as a ferry at Torquay, so I wonder if this is
the Kiloran, then that means any Fairmile B would only have been
Kiloran II and up?
There was a Free French flotilla at Dartmouth, but the SOE managed 15th Flotilla was Royal Navy. I haven't quite finished making sense of the Helford River, and Falmouth Flotillas, the latter also going by the name Inner Patrol Flotilla, but they were made up of the French styled Motor Vessels, to merge with the Brittany fishing fleet, and had French crews among them.
