LOW-TONNAGE SHIP HULL Russian patent published in 2000 - IPC

FIELD: shipbuilding; single-hulled low-tonnage vessels. SUBSTANCE: hull has upper gliding part and lower displacement part. Unit elongation of lower displacement part is L/B_l≥ 3, where L is length of ship and B_l is maximum width of lower part of hull. Width of upper gliding part (B_u) exceeds maximum width of lower part by at least 1.2 times: B_u/B_l≥ 1,2. Front submersible part of hull may be provided with hydrofoils. Gliding surface may be provided with planing steps and may have deadrise. EFFECT: optimal use of ship buoyant forces obtained due to gliding and displacement. 3 cl
