ABSTRACT:
This one-handed canoe paddle is comprised of a blade portion, a hand grip portion, and an arm cuff portion. The hand grip is integral with the blade and is at an angle to the centerline of the paddle approximating the angle which a closed hand makes with the centerline of the forearm when the hand and forearm are in alignment. The arm cuff is U-shaped, positioned perpendicular to the plane of the paddle, and connected to the paddle by a shaft that is of a piece with the blade portion and offset of the centerline of the paddle. The angled hand grip being integral with the blade, the connecting shaft being offset, and the uniquely positioned arm cuff taken together create an aggregate design which:
permits quick, easy access to the paddle;
lets the paddle be picked up and used with one hand;
provides the leverage necessary to propel the canoe in any direction without changing grip position;
allows the wrist to be held in a neutral position during use of the paddle; and
produces an esthetically pleasing unit.
