INFLATABLE MOTOR BOAT Russian patent published in 2005 - IPC

FIELD: inflatable motor boats provided with high-power outboard motors used for rescue of persons and performing domestic functions.

SUBSTANCE: proposed inflatable motor boat has open contour of sides of A-shaped form, elastic bottom and plating laid above it; plating includes transversal fore, aft and central sections; longitudinal edges of at least aft section and part of central sections are free to move in slots of longitudinal stringers which are connected with transom by means of rods. Stringers in fore part are additionally connected with rods on horizontal section of bottom by section of plating and rods in aft part of plating are provided with device for control of rod length which is made in form of turnbuckle. Rods are detachably secured to end fore transversal section of plating located on horizontal section of bottom and to transom forming obtuse angle within 135-160 deg. between them and stringers; in optimal variant, obtuse angle is equal to 145 deg. Engageable transversal edges of fore, aft and central sections of plating are detachably interconnected through U-shaped slots of transversal plates made in form of I-beams. Proposed boat ensures reduction of pressure in inflatable sides and makes it possible to regulate angle of attachment of transom depending on operating conditions.

EFFECT: enhanced solidity of structure.
