That question might best be answered on our comparison page. To sail on the water you need wing/sail shapes with the wind flowing over them at the correct angle of attack. To sail through the water you need wing/sail shapes and the right angle of attack. Fortunately, all Morfin Corp. products use wing/sail shapes at the correct angel of attack to convert our terrestrial movements into useful aquatic propulsion. Traditional kicks waste effort because of the extra drag that they produce.

To maximize your sailing potential, you can learn a simple kicking stroke illustrated to the left. Like marching in place, "in-line" kicking keeps your feet in line with your body to reduce drag. To practice this simple move while standing on land, you bend your knee only enough to raise your heel off the floor while keeping your toes on the ground. Then, whip your knee back to a straight position pushing your heel back to the ground with force. Keep your toes relaxed during this kicking stroke to maximize efficiency. By whipping your knee into place, you use your largest muscles (normally used for standing and walking) to whip your foot down. Relax your toes to cruise for long periods of time or use your toes to create more thrust and speed in the "turbo" mode. You can glide for a moment after each kick like the fish do to maximize efficiency. Learn this by alternating your legs while standing. It's a surprisingly small movement that translates into more propulsion than one would expect.

The Sail kick is a very small kick by Scuba standards. Again, the knee and the ankle do the work while letting the toes go freely to sustain high speed and high speed cruising. If you want to turbo-charge your kick, get your toes involved. This brings your lower leg muscles into play for more power, but takes more energy. Notice that the legs are barely bending and the foot moves only a short distance. This works because the fins convert this movement into aquatic propulsion by a modulated living hinge on the blade portion (this part is patent pending). The sail/wing shapes then convert the flow of water into thrust.

The mor-Fin kick keeps both feet together and moves them like a reduced dolphin kick. However, unlike the dolphin kick, the hips and torso of the diver remain still. It offers a rhythmic feeling of sailing through the water with amazingly little effort needed. Keep the pressure on the bottoms or your feet for speed, but this does take more energy. Relax your feet for efficiency but still whip your knees straight to maximize the conservation of momentum from your largest muscles to whip your feet into action.

The Sail I stroke has the legs alternating so that the knee of one leg is bent while the other one is straight. They then reverse their positions. This feels easier than it seems possible with only your knees whipping straight and your feet relaxed for the speed and thrust that you can generate because you are sailing through the water. It also uses the major muscle groups of your legs more efficiently. Because each leg is moving in alternation, the power is constant in this type of kicking stroke. Many people feel as though they are walking when making these movements, but our fins translate this walking sensation into aquatic propulsion. You can increase your speed by pushing harder with the toes and the bottom of your feet. In fact you can just use your feet and ankles and forget your hips and legs in tight environments, but this takes more energy using your calf muscles almost exclusively. We call these the Sail II strokes. All of these strokes can be seen in animation on our comparison page.
