"Sevastopol" type fish processing vessel
design 581


 In total 6 units were built from 1959 to 1962 at Leningrad. Also on the basis of design 581 were built six units "Yantarnyy" type fish carriers (design 581T) and three "Nikolay Zytsar" type training fish carriers (design 581U). This design is based on "Aktyubinsk" type refrigerated cargo vessel.
