FIELD: shipbuilding.

SUBSTANCE: group of inventions relates to small-sized ship building, namely to inflatable body vessels. Versions of four double-cased inflatable small vessels have inflatable board and inflatable bottom. First version comprises U-like housing. Upper and lower housing are connected to each other along perimeter on surface of coincidence of points fit so that upper housing serves as boards and generates cockpit area, and lower body forms a plane of ship deck and bottom lines. Second version of ship differs from first due to that on lower inflatable housing at edges of longitudinal axial symmetry are fixed on surface of coincidence of points fit two inflatable balloons, and fore end serves as front part of lower housing. Third version of ship differs from first and second due to that lower part of body has a catamaran or trimaran bottom shape. Fourth version of ship differs from first, second and third by that channel shape of lower part of body is defined by partitions of different height and can have a blind channel.
