The technique for making these fins is called Resin Transfer Molding, or RTM. This process involves injecting resin with fiberglass into a mold that results in a plastic-like fin that's both lightweight and strong.
What are surfing fins made from?
Materials Used Nowadays fins are normally made in Plastic or Fiber. Fiber fins are combining different materials to obtain better performance, and better weight and flotation ratios like honeycomb cores, bamboo core, and then glassed with fiber and sometimes reinforced with carbon fiber.

Do surfboard fins really matter?
The size of the fin is going to impact your performance. A larger fin generally will have more hold and also provide plenty of control in bigger surf. A smaller fin, on the other hand, is going to be more forgiving and loose, but you're going to sacrifice a lot of drive and control in bigger surf.

What is a Skag in surfing?
In surfing, windsurfing, and kitesurfing, skegs, usually known as "fins", are attached toward the tail of the board to improve directional stability and control through foot-steering. Fins allow the rider to control the board's direction by varying their side-to-side weight distribution.
Why do surfboards have wax?

Are quads faster than thrusters?
One point, on which Kelly Slater, Jeff Clark and most other pros and shapers who have experimented with four-fins agree upon is that quads are faster than thrusters. This is because they generate more drive through a turn and are able to hold a higher line (whether being pumped or not) on steep wave faces.

What is an egg surfboard?

Although Mattison was not the first to put the fifth fin on a surfboard, he redesigned the classic fin to make it useful and effective.
Why do waves curl near the shore?
As more and more of the wave front encounters shallower water and slows down, the wave font refracts and the waves tend to align themselves nearly parallel to the shoreline (they are refracted towards the region of slower speed).
What gives a surfboard drive?
Drive is said to how much the fins help you accelerate out of turns if you put enough pressure on them against the water. While fins by definition will produce drag for a surfboard going straight, the water surging against a fin in mid turn will produce a feeling of acceleration. This is known as drive.
