How to choose SUP fin?
For flat water paddling or entry-level sup surfing, a surf style fin 8-10” long is a great place to start. If you want more tracking performance, swap your fin for a touring-style fin 9-12” long. River and shallow water paddlers should opt for a flexible plastic fin, either d-shape or keel shape, around 4-6” long. Here’s how to decide based on your surfing style and wave conditions: small, mushy waves: quads are faster and perform better, allowing surfers to drive down the line. Big, powerful waves: thrusters provide the control needed for precise turns and late drops.For calm waters and recreational paddling, a single fin may suffice, providing stability and ease of use. However, if you plan to paddle in choppy conditions or surf waves, a three-fin setup may offer better performance and control.In theory, we should use the configuration of tri-fins in waves for maneuvers, waves that allow many bottom turn and cut back, because they enhance the maneuverability of the surfboard. We should surf on quad in fast waves with walls and barrels, for the speed and grip that this configuration of fins provides.Fin (Quad + Center Fin): The 5-fin setup, also known as a “Quad + 1” setup, allows surfers to use their board as either a quad or a thruster. It includes four side fins like a quad, and it also comes with a center fin that can be used in conjunction with the side fins to create a thruster configuration.
What are the two types of fin boxes?
The best place to begin is to determine whether you have an FCS fin box or a Futures fin box, as these are the two most common and widely used fin configurations found on nearly all modern surfboards. Flip your board around and start by looking at the fin boxes. This really depends on what you are doing on your paddleboard. If you are having a gentle cruise around the local lake or canal, then just a single fin at the middle of the back of the board is perfect. If you are taking to the surf or whitewater, then a set of smaller fins at either side of the back of the board.
What is the 4 fin setup?
The quad fin setup blends features from both twin-fin and thruster setups. It enhances speed, increases drive, and improves control in various wave conditions. Initially popularized in the early 1980s, the design has evolved over time, finding favor among surfers looking for a balance of maneuverability and stability. Fins The 2+1 is a very common fin set up, found on an array of boards including eggs, funboards, mini mal surfboards and longboards. The two side bites help to stabilise the board giving you more control, making this set up better for beginner and intermediate surfers.A 2+1 fin set-up means your board is set with two small side fins and a large central fin. It is very common on mid-lengths or longboards because it offers an excellent compromise between the maneuverability of a thruster and the stability of a single fin (to say it simply).THRUSTER: The thruster setup incorporates 3 fins (of equal size). Like the twin fin setup, it provides stability and drive but also give the rider more hold because of the centre fin. This setup is usually preferred in high performance boards, but also the ideal setup for beginner boards.A 2+1 setup will allow you to put in a center fin paired with smaller sidebites. This give the board more drive and control through turns as well as more stability.
Which fin fits which board?
A generally accepted rule of thumb is to use the same size fin (in inches) as the length of your board (In feet) so for a 9ft board you would use a 9ft single fin. We recommend using large fins if you are lighter or extra-large fins if you are heavier (read on to see our fin to weight size chart) but ultimately it comes down to personal preference whether you prefer the feel of a board with large or extra-large twin fins.With less drag in the water compared to a single fin, the twin fin setup offers a smoother and faster ride, especially in smaller, less powerful waves. This makes it an ideal board for those looking to add some flair to their surfing, as it allows for quick direction changes and a more dynamic experience.
