SURFACE SINGLE-HULL HIGH-SPEED VESSEL WITH WAVE-CUTTING CONTOURS Russian patent published in 2019 - IPC B63B1/04 

FIELD: shipbuilding.

SUBSTANCE: invention relates to ship building, particularly, to design of single-hull high-speed vessels. Proposed vessel comprises housing with smooth curvilinear outlines of hull underwater part and with maximum width of structural waterline in stern part. Vessel nose end has sharp lines – nearly straight waterlines with light bulge with inlet angle of about 10° – in combination with small splinting of frames: angles to vertical of 1–3 of theoretical frame timbers change from 17–22° in waterline area to 26–27° in the area of breakage of the board, above which the frame timbers sharply decreases down to the reverse one. Hull volume displaced to stern; waterlines are expanded to 14–15 theoretical frame timbers, smoothly passing into a section of the board with constant width, which is retained to the transom. Vessel height in transom area makes about 3.5 % of length between perpendiculars. Small frame timbers collapse combined with waterline sharp nose branches provides for “wave breaking” qualities of ship in conditions of developed roughness.

EFFECT: technical result consists in improvement of nautical qualities of ship with simultaneous provision of sufficient capacity and stability, providing high speed and enabling use of weapons and armament in conditions of developed sea waves.
