MARINE WAVE-DRIVEN PROPULSOR Russian patent published in 2013 - IPC B63H19/02 

FIELD: transport.

SUBSTANCE: invention relates to ship building, particularly, to ship propulsors exploiting energy of waves. Proposed propulsor consists of axles secured to hull to support wing-line rotary vanes running in bearings on said axles. Said vanes move up and down together with the hull and consists of separate elements. Turn of said vanes is limited by thrusts made at said axles. With ship right side moving upward, rotary elements of said vanes make helical surface with pitch φ like that of right side vane propeller screw. With ship right side moving downward, rotary elements of said vanes make helical surface like that of left side vane propeller screw.

EFFECT: higher efficiency.
