INFLATABLE COMBINED BOAT AND METHOD FOR ITS MANUFACTURE Russian patent published in 2022 - IPC B63B7/00 

FIELD: water vehicles.

SUBSTANCE: invention relates to vehicles on water, in particular to inflatable combined boats and a method for their manufacture, intended for operation, including in shallow water conditions. The combined inflatable boat includes a U-shaped hull in plan, formed by an open contour of the inflatable sides and bow, as well as a bottom attached to the hull, while at least part of the bottom is made rigid. The inflatable sides and the bottom are located so that the angle between the surface formed by the lower open line of the inflatable sides and the bottom plane of more than 0 degrees does not exceed 10 degrees from the midship to the stern. The bottom has a water tunnel in the aft part, in the profile of which at least two walls are flat surfaces located at an obtuse angle to the upper wall.

EFFECT: ensuring easy and reliable passage of the boat both in water and in low-water and waterless areas of reservoirs, while maintaining the reliability of the boat design.
