## Abstract

A single or double bladed watercraft paddle having an improved blade with a bottom edge configured to divert water flow off of a raised paddle blade to reduce the likelihood of it flowing or dripping into the watercraft, onto the paddler, or onto the paddler hands. In one embodiment, the bottom edge of the paddle blade is provided with a notch or plurality of adjacent notches, in another embodiment, the bottom edge of the paddle blade is provided with a protrusion or plurality of adjacent protrusions, and in another embodiment the bottom edge of the paddle blade is provided with a combination of adjacent notches and protrusions. The notches and protrusions may be of various shapes and sizes.

## Claims

### Claim 1

A watercraft paddle for use by a paddler in propelling a human powered watercraft, comprising:
a paddle selected from the group consisting of a double blade paddle having a blade affixed at opposed ends of an elongate shaft, and a single blade paddle having a blade affixed at one end of an elongate shaft, the shaft of sufficient length to be gripped by hands of the paddler, the blade having a longitudinal top edge and a longitudinal bottom edge; and
at least one protrusion disposed at a location along a portion of the longitudinal bottom edge of the blade that juts laterally outward a distance beyond the periphery of the longitudinal bottom edge configured to divert water off of the blade in a direction outwardly and away from the longitudinal bottom edge of the blade when the blade is raised and the elongate shaft gripped by the hands of the paddler is disposed angularly relative to a horizontal position and thereby reduce likelihood of water flowing or dripping off of the raised blade into the human powered watercraft, onto the paddler, or onto the hands of the paddler.

### Claim 2 (depends on 1)

The watercraft paddle according to claim 1, wherein
said at least one protrusion is selected from the group consisting of a square or rectangular protrusion having two straight parallel side walls that jut laterally outward from the longitudinal bottom edge of the blade and terminate in a straight outer end wall, a wedge shaped protrusion having two straight side walls that jut laterally outward from the longitudinal bottom edge of the blade and angularly toward each other and terminate in a straight outer end wall, a trapezoidal protrusion having two straight parallel side walls that jut angularly and laterally outward from the longitudinal bottom edge of the blade in a direction toward the elongate shaft and adjoin a straight outer end wall, a trapezoidal protrusion having two straight parallel side walls that jut angularly and laterally outward from the longitudinal bottom edge of the blade in a direction away from the elongate shaft and adjoin a straight outer end wall, a triangular protrusion having two straight side walls that jut angularly and laterally outward from the bottom edge of the blade converging at an apex, a truncated triangular protrusion having two straight side walls diverging angularly and laterally outward from the bottom edge of the blade terminating at a straight outer end wall, a convex arcuate protrusion that juts laterally outward away from the bottom edge of the blade, and a combination thereof.

### Claim 3 (depends on 2)

The watercraft paddle according to claim 2, wherein
said straight side walls and said straight outer end wall of said at least one protrusion that juts laterally outward from the longitudinal bottom edge of the blade are adjoined by a smoothly rounded juncture to avoid sharp edges.

### Claim 4 (depends on 2)

The watercraft paddle according to claim 2, wherein
said at least one protrusion that juts laterally outward from the longitudinal bottom edge of the blade comprises a plurality of protrusions disposed in laterally spaced apart relation along the longitudinal bottom edge of the blade.

### Claim 5 (depends on 2)

The watercraft paddle according to claim 2, wherein
said at least one protrusion that juts laterally outward from the longitudinal bottom edge of the blade comprises a protrusion disposed at a juncture of the elongate shaft and the longitudinal bottom edge of the blade that juts angularly outward beyond the juncture of the elongate shaft and longitudinal bottom edge of the blade.
