Ever turned up to a beautiful lagoon and the wind is just too light for you to ride?


Our Hydrofin™ concept will enable kitesurfers to ride in lighter winds and shallower waters - more availability, more accessibility, more fun!

The current design is now out for test!

the story so far

We have had exciting feedback from other people testing.

The design has been ridden by others, the sensation is more of a skipping effect across the water. The best conditions to try it in are flat water and slack water conditions (low current).

You will need reasonable power to get the best out of this ride, we find it is like going up a board size.

We are excited about what this product can offer YOU and we are looking for innovators and those that love to be the first to try products to join us in our journey!

We want to get you out there riding more often, having more FUN on the water!


Our Design

Here are Forty1 Kitesurfing, we have developed the Hydrofin™ which is:

  • A small portable kit

  • Retrofits onto your existing kiteboard, so you need less kit

  • Similar riding style to your twin tip kiteboard

  • Able to be ridden in shallower water


Why do we love kitesurfing?

We absolutely love being outdoors, and have a real passion for the simplicity of kitesurfing, being pulled along the water simply with the power of the wind!

Have you ever turned up to a beautiful lagoons and the wind is too light? Existing hydrofoils have optimised their lift to allow you to clear any chop. This put them over 1m high, meaning shallow waters are out.


3 Hydrofoils for bi-direction

The board is setup with 3 Hydrofins™, at any one point you would be riding on 2 of the Hydrofins™, the middle one creating the primary lift with a rear one for stability and balance.

Less kit, more fun!

Why buy that bigger board or even that bigger kite when you can retrofit our Hydrofin™ onto your existing kiteboard, allowing you to enjoy more conditions with less bulky kit! Let us get you out on the water more!


Extensive analysis

We have run the analysis to optimise the design performance and reliability. Running fluid analysis allows us to understand the lift and drag of the design. Performing structural analysis allows us to make the design strong enough to withstand whatever you can throw at it.


We’d love to hear from you

We love this board and we want to get it out there. Find us on the beach for a trial and let us know what you think.
