摘要

An oar rowing device that may be configured to accommodate a canoe, rowboat, rowing skull or any similar watercraft using an oar rowing device. This oar rowing device blade is equipped with one or more multi-blade propeller housing each having a multi-blade propeller. Each propeller housing with a multi-blade propeller is open on both sides of the oar rowing blade. This oar rowing blade may also be equipped with cone shaped orifice housings through the oar rowing blade each having a center rotating cone shape with inner ribs and grooves. The pulling stroke of the oar rowing device generates the kinetic energy to put into motion the multi-blade propeller and the inner rotating cone shape orifice device.

主权项

1. An oar rowing device for maneuvering or powering a watercraft comprising:
a shaft having a first end and a second end; an oar rowing blade having a proximal end and a distal end and coupled to the second end of the shaft; the oar rowing blade comprising;
one or more multi-blade propeller housings mounted therein, each having a multi-blade propeller; each propeller housing being open on both sides of the oar rowing blade;one or more orifice device housings through the oar rowing blade;a device rotatably mounted within each orifice device housing, each device comprising a cone shaped through hole defining large and small openings, inner ribs and grooves; the large opening of the cone shaped device being on the face side of the oar rowing blade and the small opening, or discharge side, is on the opposite side of the oar rowing blade device; wherein a pulling stroke of the oar rowing device forces water through the propeller and orifice device housings to rotate the respective propeller or device therein, thus increasing water pressure-through each propeller or device to reduce the physical effort of pulling the oar rowing device through the water.
