Abstract RU 2495781 C1

FIELD: transport.

SUBSTANCE: invention relates to ship building, particularly, to design of ship aft with water-jet propulsors. Ship tunnel-type aft has clear-water hull and underwater hull with bottom with at least one lengthwise cross-section arc-like channel extending along the entire ship hull under design waterline. Underwater hull cross-section profile along design waterline features maximum width at aft area. Bottom surface between the walls of boards and channel are shaped to half-cones with vertices at ship bow and vertices at ship aft. Water-jet propulsors are built in said half-cones at underwater ship aft. Extra water-jet propulsor is built in ship aft lengthwise channel top part.
