I went deep into the story od SV Cariboo following all her modifications (and I redrawn my first drawing).
Launched as
Fort Reliance in 1986, she was converted into
Cariboo and chartered to the Italian research program in Antarctica.
After a couple of years was sold, renamed
Droit de Parole and used as "pirate" radio ship in the Adriatics Sea in front of the former Jugoslavia.
Later she was again modified as a more standard SV and renamed
Veesea Pearl.
But at the end, renamed
Pearl she looks more or less as the very first version!
