Related QuestionsWhat's the deal with the split fin?
inside the storeWhen using traditional fins you kick from the hips and make broad strokes, moving the water below or above the fin. The split fin is designed to push the water out behind you using a propeller-like design, giving you more energy per kick. Because of the way the split fin is used, lower leg muscles are used instead of abdomen and upper leg muscles. This gives you longer bottom times (because you conserve air), and allows you to use smaller kicking motions.

Related QuestionsCan I get a thruster fin for my shortboard?
Wavegrinder Surfboard Fins | FAQsYes, but different by design. Today's fins mostly look like 1960s and 1970s sailboat keels. The Wavegrinder has been compared to many things, notably to today's America's Cup boat keels and rudders, airplane tails, airplane wings, and even to submarine conning towers. This of course makes sense, because air and water both are fluids and behave quite similarly. But look and you'll not find modern hydrodynamic fins that looks like today's surfboard fins.
Related QuestionsWhat fin box does it fit?

Boxes from the same manufacturer vary slight too sometimes, and with wear and use, boxes will loosen up over time.

Related QuestionsWhy is the fin so upright, and not raked?
Wavegrinder Surfboard Fins | FAQsAnother factor that increases drag by increasing the tip vortex is rake, or sweepback angle, combined with a high aspect-ratio. The more vertical and the thinner the fin, the smaller the turbulent vortex becomes. Those of you familiar with boat design have seen the evolution in keels and sails from low aspect, heavily raked keel, rudder, and sailplan designs in the early to mid 1900s to the high-aspect more vertical designs over the past 20 years or so.
Related QuestionsWhat can be done to minimize the fin-tip vortex?
Wavegrinder Surfboard Fins | FAQsDecrease the sweepback angle. Increase aspect ratio. Create a fin shape (planform) with an elliptical lift distribution. Add an endplate, wings, or winglets.

Related QuestionsQ My fin is bent and twisted. Why?
SAILSetc - FAQsA We cure our foils at a temperature only slightly above normal room temperature. They are black and when exposed to sunlight, or when left in a car on a hot day, they may reach temperatures in excess of 70 degrees C. At this temperature the resin will soften and, if there is any load acting on the keel, it will distort. Often this happens when the boat is laid down on the ground between races. The boat is picked up and placed in the water.
Related Questionstop)Q5. How do I choose the right fin?
Snorkel Hawaii - Frequently Asked QuestionsMost fins are gender-neutral and your shoe size is a good guide to determine what size fin may fit you best. If you wear shoe size 8, try fins sized 9-10 first and then go up or down in size depending upon their comfort. You want a fin that fits comfortably and is not so big that your heel pulls up from it when flexed. Fins tend to expand in water and a loose fin may slip off. A snug fit is always best. When choosing fins it is a good idea to get one that floats.
