Thanks a lot! :)

Here you can see the specifications and a list of known vessels of 431 project, which had a few modifications, and details and photos m/v UNZHA:

Thank you very much for identifying this vessel. I will later post some pictures of her in the category general cargo ships built in the 5o'ies.

Excuse me.
This 1st modification of such dry cargo, project 431.
They were built in the years 1951-1960 on 8 shipyards in the USSR, including Ilyichevck Ship Repair Yard.

This ship was built in 1958 by Vyborg Shipyard as UNZHA, in June 2004 renamed UNZHA-1, homeport Doroginya (Kostroma Region, Russia), the number of Russian River Register 026472.

Thank you Sergey. I see slight differences from the drawing, but from 32 ships built there were possibly some modifications underway, and maybe some rebuilding was done over the years also. Is it possible to figure out which one of them this one can be, and her history? Could her current name be UNZA..?

Dry-cargo ship S-201 type, project 1526.
Built in 1959-1963 on Ilyichevck Ship Repair Yard, Odessa region, USSR.
Total built, least, 32 ships.

Best Regards,

Call-sign UNZA apparently belonged to Kaliningrad trawler ANCHAR (IMO 6612984) of 1966 which was scrapped in 1995. I don't know whether Russia re-allocates call-signs - some countries do, others don't.

Agree re RB-150 design

but cannot find list of these.

Thank you for your reply. The crew told that she is a former military vessel...

It looks like a modification refrigerating fishing boat RB-150 type (proj.718), built since 1957 in Kerch. rgds
