BOAT-CATAMARAN Russian patent published in 2005 - IPC

FIELD: shipbuilding; building boats-catamarans for scientific work and pleasure boats for inspection of surface of fresh water and sea water basins.

SUBSTANCE: proposed boat-catamaran has floats located symmetrically relative to longitudinal axis and rigidly interconnected; floats are made in form of elastic gas-tight cylindrical skegs-pneumatic balloons. Each of them is located between flexible couplings and is engageable with its lower and upper surfaces by means of changeable safety ski and one of pylons. Pylons give support for disk-shaped cabin consisting of convex spherical upper and lower sections hermetically interconnected through intermediate all-round vision segment provided with bearing flange, control system and power plant mounted on transom plate which is secured on pylon bases. Boat is provided with float draft control mechanism which is made in form of gaseous working medium pressure regulators in cavities of floats-pneumatic balloons; it is connected with compressor receiver by means of gas lines. Power plant is provided with hinged column which is swivel in horizontal plane. Each float is provided with additional skegs-pneumatic balloons giving support for main skeg-pneumatic balloon along longitudinal axis. Lower spherical section of said cabin is provided with blisters in form of hermetic port lights in bottom. Pylons and changeable safety ski are provided with cradles engageable with main and additional skegs-pneumatic balloons by equidistant surfaces. Bearing flange of intermediate all-round vision segment of disk-shaped cabin is secured on pylons.

EFFECT: extended field of application.
