Great photo. Many thanks for posting this one. I think IMO should be 5022065. Regards,

Wonderful shot, but what interested me most was the small passenger ship in the background. I checked it out and my suspicion turned out to be correct: it's the WEST STAR (ex-CABO IZARRA of 1967). This ship was named WEST STAR between 1970 and 1975, when she became the DOÑA MONTSERRAT. Thus we can date the picture to the "early 70s".

Here is a picture of the WEST STAR: http://www.cardcow.com/211355/mv-west-star-transportation-boats-ships-cruise/
