ABSTRACT:
This invention is intended as an improved swimming aid for the hand. It is a ridged paddle having several features to enhance the paddles' performance for enjoyable swimming. The paddle has a finger tip hood that permits the fingers to extend unobstructed through finger facing apertures. The paddle has a wrist portion having a wrist strap. A thumb notch formed at a lateral end, by the palm potion of the paddle. The palm portion has a Transverse Ridge, that together with two lateral flanks form a triangle of three major bends at the palm. And, with two bends for the finger apertures and finger tip hood, change the paddles' shape from a flat surface to a three dimensional form, that deflect water, adds structural strength, and aids in hand comfort. The arrangement of these features, provide an enjoyable instrument that facilitates good leverage in the water.
