Very interesting photo. She was build as Osco Sailor for the Norwegian company Ole Schrøder & co ( OSCO ), as one of four sisters. Osco Sierra, Osco Stripe and Osco Spirit.
In 1979 she was on charter to H.E.Hansen-Tangen, Norway and the name was changed to Osco Linea. In 1982, she was back into the Osco fleet and renamed again to Osco Sailor.
In 1987, she was sold to Petrobulk and renamed Petrobulk Ruler.
She was then renamed : Anett, Anett II, Chopin and finally Chopin III.
(ex AB on the Osco Sailor 83 ) :-D
