ABSTRACT:
A foot mounted fin for use by body surfers, divers, and swimmers in water activities of all types. The strap of the swim fin fits around the ankle while the fin blade extends out beyond the foot. There is a scoop section designed to take in water at the top of the fin near the foot. Scoop discharge ports for discharging water is at the blade tip. The scoop section also channels the water to eyelet ports formed into the fin blade, enabling it to discharge water out and over the bottom surface of the fin blade while at the same time releasing it at the blade tip. This combines the forces of the two jet streams of water. This fin works with wave turbulence and ocean currents enabling the body surfer, diver and/or swimmer to fully utilize the power potential from the ocean on his/her behalf. This fin also includes side rib extensions to increase blade width and surface area without making it too long. In addition this fin may also come with an adjustable foot chamber, and/or foot chamber lining, and/or adjustable ankle strap to maximize comfort and fit while at the same time enabling one pair of fins to fit a variation of foot sizes.
