Fins provide you with control as you shift weight, steer the board, and turn. The more fins you have, the more stable your ride is going to be.
On a normal surfboard, the position of the fins is different from what you find on a jetboard. When you’re riding a surfboard, you’re on a downward slope — the momentum of going down the wave is the force that’s driving you forward. On a jetboard, the force of the jetpack at the back of the board is what’s driving you, so the pivot point is different.
Since the pivot point is different, you cannot put fins under the anterior like you would with a surfboard. Instead, if you are using a pair of fins, they need to be placed at the back of the jetboard where the pivot point is.
Our Freeride and Carve boards both have a twin setup with two fin boxes at the back of the board, whereas the X-sport has a quad setup with four fin boxes (two at the front and two at the back) to offer more configuration flexibility.

You may have to use some force to insert and remove your fins from the fin boxes. To insert, we suggest protecting the heel of your palm with a cloth or towel and firmly tapping your palm into the outside edge of the fin until it pops into the box.
To remove, wrap the cloth or towel around the point-edge of the fin and, using the heel of your palm, firmly tap upward inside the curved edge until the fin pops back out.
