FAST SHIP Russian patent published in 2011 - IPC B63H9/06 B63B1/16 B60V1/08 

FIELD: transport.

SUBSTANCE: invention relates to ship building, particularly, to construction of yachts. Proposed ship has bearing hulls equipped drop keel and water rudder jointed with aerodynamic wings arranged between hulls and propulsor. Ship is equipped with, primarily, sail propulsor, and comprises two hulls rigidly jointed together by crosswise beams. Two independent-control aerodynamic wings are pivoted to two beams between said hulls with clearance varying from 25-50% of wing chord to ensure angle of attack varying from 0 to 12 degrees. Note here that pivot pin of each wing pivot joint is spaced from its front part by at least 30% of chord, while every wing is provided with at least one drag link to vary wing angle of attack. Side planes of aerodynamic wings and those of hulls facing the former made be straight and parallel with clearances there between being sealed by resilient sleeve gaskets, while hulls outer contours may be curved.

EFFECT: minimised rigging, both fast and moderate-speed sailing.
