Thank you, Igor, for the correction. Much appreciated.
Do you have any builders names, owners or history of the Okhotsk tug?

Do you believe that both tuugs were originally MB-6121?

This is different ships, different projects. KAPITAN ZAGORSKIY - project 8057 http://www.shipspotting.com/gallery/photo.php?lid=982646, http://www.shipspotting.com/gallery/photo.php?lid=1365512. This tug of the project 1496 - http://www.shipspotting.com/gallery/photo.php?lid=1377694, http://www.shipspotting.com/gallery/photo.php?lid=1452521

Was listed as KAPITAN ZAGORSKIY ex MB-6121 when operated by A/O 'Dalryba' and based at Petropavlovsk-Kamchatskiy. I presume that she has a different operator at Okhotsk and has reverted to original MB-6121. Grateful for confirmation. Identity of present owner would be particularly welcome.
