When it comes to surfboard fins, all fins are not created equal. You need different fins for different boards in different conditions. If you want to get the most out of your time on the water, it’s important to select the right fin. Here is our complete fin guide for your surfboard.

Thruster

A thruster fin consists of three individual fins, typically one on each side and a center fin. The fins are usually all the same size, but the center fin can be smaller giving the board more of a “release” feeling. The thruster fin is considered the most high performance set up and is what most shortboarders use. This fin is a popular fin due to it being good for maneuver-based surfing.

Twin Fin

A twin fin is exactly as the name implies, two fins. The fins are set by the rails on the board. These fins typically use a larger fin template and a keel fin design. Twin fins are great for speed and flow. These are the fins we recommend for those looking to get the most out of the Folly Beach waves. Twin fins are a great option for those looking to take advantage of weak or subpar conditions. Twin fins can make your life far easier in these conditions.

Quad Fin

Again, a quad fin is exactly as the name implies, four fins. This set up consists of four fins, two fins on each side of the board by the rail line, with no center fin. These fins are known for their speed and are a great option to use in large surf conditions where sliding is not ideal.

Single Fin

A single fin consists of just one fin. This set up is typically found in long boards and on alternative shapes. These fins offer hold and are known for their ability to turn and pivot. They allow easier nose riding making them a standard set up for long boards.

Fin Shapes and Sizes

All fins come in a variety of shapes and sizes. We recommend when first starting out to get the correct size fin for you and to keep it simple. Fin sizes are based on the surfers weight and include:

• Extra Small (for surfers weighing 75 and 115 pounds)

• Small (for surfers weighing between 105 and 155 pounds)

• Medium (for surfers weighing between 145 and 195 pounds)

• Large (for surfers weighing 180 plus pounds).

Obviously, you can tell there are some discrepancies with weights and some “in between” sizing options to choose from. It’s important not to get worked up about fin size, design, or the small intricacies of individual fins and set ups. As a beginner, you most likely won’t feel the difference. The difference is only truly felt when you advance in your surfing. It’s important to pick a set up that makes your life easier and creates speed for you in softer conditions. like those we have here in Charleston.

This guide is just a general overview of fins. You can always consult one of our surf instructor or a board shop for more specific fin questions. In the meantime, try out a set up and see how it feels. If it doesn’t feel right, move on to a different set up, until you find the best set up for you.
