Abstract
Fishing in the coastal marine zone in the Russian Federation is currently carried out by small fishing vessels of domestic and foreign construction. The vast majority of vessels have exhausted their resources and require replacement, while foreign-built vessels show more efficient operation compared to domestic counterparts. Measures to modernize Soviet and Russian vessels do not give the desired effect. Information on modern foreign fishing vessels is classified or very limited. Because of this, the designers are faced with the task of modernizing existing vessel designs and / or creating a design for a new competitive fishing vessel for efficient operation. An analysis of modern foreign vessels information shows that all small fishing vessels basically have two types of hull – "Icelandic" and "Norwegian", characterized by an increased completeness of contours. Studies of modern small fishing vessels with a large hull density, by testing physical models in the towing tank, made it possible to determine the main elements of vessels that significantly affect seaworthiness. This paper describes a series of tests of physical models of ships in the towing tank. Based on the results of these tests, the main elements of small fishing vessels with a large hull density, which largely affect certain seaworthiness, were identified. Based on the results obtained, recommendations were formed and presented for use in the modernization of projects of small fishing vessels and / or the creation of new vessel designs.
