The C4 Wahoo plastic blade is designed to obtain the necessary curve and parabolic flex in the blade. Of all the possible parabolic curves the most ideal one is the one water pressure places on fish. The body of a fish tapers toward the tail where the most flex occurs and this is a key concept in fins as well. The fin blades gradually flex more toward the tips of the fins starting with the stiffest section at the foot. A blade which flexes visibly at the foot-pocket will not transmit the energy efficiently through the fin stroke. The Wahoo fin blades extend all the way to the heel therefore transferring the maximum amount of energy. In the Wahoo a Flap shape patented by C4 allows for the best parabolic curve flex with minor absorption of energy and a more efficient release of water stream from the blade (see C4 Flap). The excellent results of the C4 blades since 1990 guarantee the highest performance of our products and affirm the correct choice of technical choices employed in our production.
Water Rails - Water rails invented by C4 in 1994 serve the function of channeling water over the blade. They allow for a more stable kick stroke as the fin moves as if its riding on two railroad ties. In standard freediving application where the performance is tested in a controlled environment such as a class and a pool, doing a strait underwater swim on the bottom of the pool with constant unchanging loads, performance is achieved with a combination of minimum waste of energy and maximum speed.
Spearfishing applications are different where ease and maneuverability and variable load effort and sudden movements are the norm. Low water rails displace less water making these movements easier compared to high water rails which are better suited for standard freediving applications.
The parabolic shape of the Water Rails in the Wahoo best lend themselves to a wide variety of freediving and spearfishing applications. The Wahoo blade is the only Freediving and Spearfishing plastic blade on the market to include side rails for a competitively priced high end freediving fin.
The least amount of hydrodynamic resistance occurs when the diver is in a vertical position with the head toward the surface and the fins fully extended downward which has in one axis all the joints of rotation: the butt, knees, calves, metatarsal and fin blades. This can only occur when the fin blade is placed under the metatarsal like the C4 Wahoo blades with a steep angle, more than 23 degrees in the Wahoo. Vice versa, with traditional foot-pockets with a lesser inclination a dis-alignment is created in comparison to the body of the diver. This will force the diver to incline their back during the kick stroke in order to swim in a strait line. When the alignment of the blades compared to the diver is significant damage can occur to the knee joints and calves. With the C4 Wahoo blades this does not occur, ergonomics are at the highest level.
· C4 Wahoo foot-pockets are produced conferring the hydrodynamic needs, for one because they have an enclosed and flared shape of the foot-pocket and also because of the absence of foot-pocket ribs. The absence of foot-pocket ribs has sensibly reduced the front section of the foot pocket thereby reducing hydrodynamic resistance.
