SUP Fins for Control, Stability & Direction

A SUP fin is one of the most important and most exposed parts of a paddle board. It plays a key role in maintaining stability, tracking straight, and improving overall control. With the right fin, your board glides straighter, feels more stable, and performs better—especially over longer distances or in more demanding conditions.

Because fins are exposed to impacts, they can get damaged or lost. That’s why we offer a wide selection of SUP fins and spare parts, so you can quickly replace a damaged fin and get back on the water.

SUP Fin Materials – What’s the Difference?

SUP fins are made from different materials that affect weight, stiffness, and performance.

Plastic SUP fins

Durable and affordable
Lightweight
Ideal for beginners and recreational paddling on flat water

Fiberglass SUP fins

Lighter and stiffer than plastic
Better power transfer and tracking
Improved control and efficiency
Great choice for intermediate and advanced paddlers

Carbon SUP fins

Lightest and stiffest option
Maximum performance and speed
Faster acceleration and better energy transfer
Designed for advanced paddlers and racing

Touring SUP Fins – What Size Should You Choose?

The size of your center fin significantly affects stability, tracking, and versatility.

9-inch Fin

Ideal for sea, lakes, and longer distances
Classic touring size
Excellent tracking and stability
Often included with sport/touring SUP boards
Helps maintain straight paddling and higher cruising speed

8-inch Fin

Versatile all-round option
Suitable for mixed conditions
Better for slightly shallower water
Good balance between tracking and maneuverability

7.3-inch Fin

Designed for rivers and shallow water
Flexible rubber construction
Less likely to snag on obstacles
Extremely durable and impact-resistant
Ideal for low water levels and river paddling

Screw-In Touring Fin

Most center SUP fins attach using a screw and plate system (US box style), ensuring a secure and stable fit.

A screw-in fin:

Provides stronger attachment
Improves tracking and control
Prevents unwanted movement
Performs better at higher speeds and longer distances

For proper installation, you’ll need a fin screw and plate to keep the fin securely fixed.

River SUP Fins – Less Snagging, More Safety

For river paddling or shallow conditions, shorter rubber SUP fins are highly recommended. They are more flexible, reduce the risk of snagging, and are nearly unbreakable. This improves control and safety in moving water.

Spare Parts for SUP Fins

If you lose a fin screw or damage your fin box, we offer replacement parts to get you back on the water quickly. Available parts include:

Fin screws and plates
Replacement fins

Mounting accessories

Choosing the right SUP fin improves tracking, stability, and overall paddling experience. If you’re unsure which fin suits your board and paddling style, we’re happy to help you choose the right one.

FAQ - NAJPOGOSTEJŠA VPRAŠANJA

Can I use the sup without a turn signal?

The sup board can also be used without a turn signal, but it will be much less stable and difficult to control. Without a turn signal, maintaining direction is difficult, so use without a turn signal is not recommended.

Do all sup turn signals fit all sup boards?

No, the turn signals differ depending on the mounting system and the shape of the fin box. Before buying, it is necessary to check whether the turn signal corresponds to the type of fin box on the sup board.

What happens if I use the wrong size turn signal?

Too big a turn signal can make maneuvering more difficult and get stuck more often in shallow water, while too small a turn signal makes it harder to keep the course. The right size improves control and swing efficiency.

Is the turn signal for the sup sensitive to shocks?

The steering wheel is one of the most exposed parts of a sup board. If it hits the bottom or an obstacle, it can be damaged, so it is recommended to check the condition of the turn signal after blowing in shallow water.

How do I know the turn signal is correctly installed?

The turn signal must be aligned in the fin box and firmly fixed with a screw and a plate

Does it make sense to have a spare turn signal?

Yes, a spare turn signal is highly recommended as a turn signal can be damaged or lost quickly. The spare turn signal allows you to continue driving without interruption.
