HULL OF DISPLACEMENT SHIP-HALF-TRIMARAN Russian patent published in 2015 - IPC B63B1/02 B63B1/12 B63B1/00 

FIELD: construction.

SUBSTANCE: body of a displacement ship-half-trimaran comprises a fore part with entrance lines of a single-hull displacement ship and an aft end with entrance lines of a trimaran, comprising a middle main hull and two comparatively narrow side hills - outriggers. The specified elements of the trimaran aft end form two tunnels between each other. Outer boards and a deck (decks) of the fore part smoothly change into the outer boards of trimaran outriggers and a deck (decks) of the aft end. In general the ship hull has smooth entrance lines corresponding to the displacement motion mode. Between the fore part and aft end there is an area of smooth mutual transition of their entrance lines, including two symmetrically arranged side sections of the bottom arranged relative to diametral plane of the ship hull, which smoothly rise along the length of the ship from the single-hull fore part to the existing water line in tunnels between elements of the trimaran aft end.

EFFECT: improved operating characteristics of a ship, including its navigability.
