Stand up paddle board fins are so important, such that you should never even think of going into the water if your board has no fin.

3 vs 1 fin SUP: How They Work

How many fins should a paddle board have?

Now that you know how important a SUP fin is, how many should your board have? Well, it either comes with one or three fins. If it has one, it is just one large fin that is set up in its fin box with a screw and nut, tightened fully.

For the paddle board to run or to track, it will need the fin to move back and forth. This is why all sup boards have a channel in which the fin moves backward or forwards.

If the owner of the board pushes the fin forward, it improves the steering and turning. If he/she pushes it backwards, it helps the board to track better.

If your board has three fins, it tracks much better than a 1-fin SUP board. Also, you can remove the center fin and keep the two side fins and the board will track just fine.

However, please note you can only mind about the tracking when you are paddling on flat water. If you are paddling in wild water, you will need to move the center fin, which is the largest, forward to help with the steering.

The same also applies if you are paddle boarding in waves.

Racing fins

Racing fins mostly come in the rigid style, but it is also possible to find some that come in the flexible style. Rigid racing fins are good for tracking when racing down water.

Flexible racing fins are good for tracking in debris and rocks. When they hit a solid item, they give way therefore preventing you from falling headlong into the water. Besides, flexible fins tend to help you navigate solid obstructions in a much better way.

If you are doing whitewater stand up paddling, consider the flexible fins if there are logs, rocks and other obstacles. This fin will just flex around such, allowing you to paddle along.

The anatomy of a paddle board fin

It may look simple and small, but there is nothing small about how it operates. So what makes up the paddle board fins?

Fin materials

The paddle board fin can be made of fiber glass, plastic or carbon fiber. Of course, plastic ones may be more affordable.

Inflatable SUP fins are usually made of rubber. Basically, when you are buying a paddle board replacement fin, you can try any material that you fancy.

The paddle board fin structure

First, there is the base which is the widest and the top part of the fin, you know, the fin that goes into the channel in the board that has been designed for just that.

Then there is the tip, which is the narrow end of the fin that drops into the water. It affects how your board tracks and the speed too.

The leading edge of the fin is the front edge of the fin. It helps with the steering and turning of the board. Also referred to as the sweep or rake, it helps the board to lose weeds that it might collect as you paddle.

The trailing edge is the other edge – the back edge of the fin. It, too, slows or increases the speed of the board as well as helping in the steering.

Are paddle board fins universal?

SUP fins are not universal. Therefore, when you are looking for a fin replacement for your paddle board, you need to find one that is compatible. Of course, the channel or box on the board where the fin fits is going to guide you.

On the same note, SUP fins are interchangeable. This means you can use different types of fins on the same board. Probably that is why we recommend that you get different types of fins for your boards.

For instance, a long fin is good for balance and stability. A racing fin is good for down river paddling while other fins are good for flat water paddling.

If you have all of these fins, you can transform your board from a flat water SUP to a racing SUP in a moment.

Overall, how to put fin on paddle board is very simple. You will hardly need any assistance since it is so straightforward and it requires minimal tools.
