Looking for a photo of this vessel which was built in 1923 and continued in private yacht service up through 1938 and which may have been involved in the allied bombing of Piraeus, Greece on 11-1-44 .Here is a Lloyd's Register Of Yachts entry for her.
Here is part of a discussion regarding the WWII bombardment of Piraeus and the possibility the Karen was sunk or damaged as a German war vessel.
In the Index of Motor Yachts of British yachting magazines, there is an entry for Karen in the August issue, 1923, "Motorboat & Yachting". Does anyone know of a repository where this magazine might be archived?
Well, I asked the museum which maintains the Yacht Design database to send me the 1923 article on "Karen", and voila! They sent it!
