Thanks for your help ,lads! I had spotted the different window layout but still thought that she was the Bonanza,as that vessel operated out of San Sebastian.Which was much more familiar territory to me than Northern waters. I cannot fully decipher the info in Faktaomfartyg so cant work out where I would have seen her. One thing I am sure of is that I took the photo between November 1982 and June 1987. On the basis of the davit and window count it has to be the Buenavista

Yep, saw it to late. Not to good a detective, but it was close, hehe! Close but no cigar.
