WHY USE ASSYMMETRIC FINS?

KA Sail released the first ever working production asymmetric speed fin in 2006 with superb results. This fin was (and still is) an outstanding performer up to 50kts, claiming national records and holding GPSSS outright speeds right up until the canal in Luderitz opened up a new era in windsurfing records. The design brief at the time was to make a fin that could easily get to 50kts. It was the first production fin to do so back in 2009.

The benefit of a correctly designed Asymmetric fin is that on the “ON” side, the maximum available lift can be a lot greater than an equivalent symmetric fin with the same top speed capability, and also the drag is appreciably lower. So it’s a win-win situation for really high speed sailing, and you can get away with a lower surface area. The downside is sailing the other tack, where the maximum lift will be significantly diminished.

WHY A TRIBAL ASY?

There are many trade-offs in fin design, especially when it comes down to doing really high speeds. Basically, you need to use thinner profiles as the design speed goes up. Also the more asymmetry (camber) you put into a fin, the thinner it has to be. There is less margin for manufacturing tolerances, and structural limits are quickly reached. There is also a fundamental trade-off between low speed performance and high speed capability. The details of this are beyond the scope of this introduction.

DESIGN CHALLENGE

This creates a considerable design challenge. It’s easy to add some camber and make a fast fin by flattening one side of a standard foil, but what you end up with, is a sub-optimal fin that will have higher drag than necessary. It won’t be useable on the other tack, or at best this will prove very difficult. And it’s also likely to be average at both low speeds and high speeds thanks to its thickness.

TACK PERFORMANCE

So with these trade-offs in mind, we set to work on the best all-round shape to accommodate these issues, and found a nice balance that sacrifices none of the “ON” tack performances, extended out to significantly higher speeds than the earlier KA series. The “OFF” tack performance is remarkable for an asymmetric fin and offers an easy ride back upwind, without the constant spin-outs and crashes associated with other designs. On the run, these fins offer superb low drag performance and confidence to break records. These fins are of course available for both tacks.

FIN BOXES

The ASY SPEED G10 will be available in Tuttle box only.

FIN BASE

The fin box consists of a G10 base covered with blue PU resin for easy sanding to fit your board. The full G10 base is strong and durable, and will withstand the powers which will be transferred through the fin to your board while riding.

G10

Our G10 fins are produced from high quality G10 plates from China. All G10 fins are produced and processed in our European factory on precision CNC machines and hand-finished by our crew.

PROFILE

Serious R&D based on windsurfing optimized profiles has led to an unsurpassed performance in a fin.

On the run, these fins offer superb low drag performance and confidence to break records...

FAQ

My fin doesn't fit in my board...

In practice, we see many boards with different boxes, so it’s always hard to get the perfect fit for all boards. Please do not be afraid to sand the box down a bit to get the perfect fit for your board. Also be aware, that if a fin sinks a bit into the box, it is not an issue. However, a fin that sticks out above the box is an issue and needs sanding down. If you do not feel comfortable with the fit, please do not hesitate to contact us.

For which fin boxes do you produce your fins?

We make our fins in Tuttle, Deep Tuttle and Power Bases. Per model you can specify what base you would like as long as the desired base is available for that certain fin. The ASY SPEED G10 comes in Tuttle Box only.
