Abstract

The invention relates to a nautical propulsion device having improved economy and improved control of the masses of water used. Said device consists of a "supporting base" (B) (handle or bar), which extends a "blade" portion also known as a "dynamic fuselage" or "reactor" (A) consisting of a single "wall" (1) or "wall structure" completed by at least one "opening or channeling furrow" (2); the "blade" of same being used at 90°, as opposed to a conventional oar, resulting specifically in the water surging thereupon being constrained so as to process the flows thereof propulsively; the "wall" portion is defined along a mean center line of symmetry (C) which formally qualifies same as the principle of a sufficiently tapered "leading edge" or "section" (3) for accurate control and steering. The device according to the invention is intended specifically for propelling water craft.
