Notices:
        - During construction of a series of vessels of one project, in their design some changes can be made and the above-stated characteristics can be changed insignificantly.
        - The above-stated characteristics are taken on the vessel STB-2041 (source - Fishing industry fleet. Reference book. 1960). In brackets you can see characteristics of STB-7132 (source - Fishing industry fleet. Reference book. 1972).
