Introduction

The WTF range currently consists of just this single template, but it is something else. It is very hard to classify this fin as it is so unusual and yet is an unbelievable performer.

Don't let the look of the fin throw you off. There is a lot going on with this fin and it delivers, big time. The simplest description for this fin is that it represents a super canard-style fin. The fin is not just a simple vertical fin it has two distinct breaks in its profile with the central blade area flipped out by 7º and the trailing tip extension at 25º. This fin has to been seen to believe what is going on with the shape.

It is most commonly used with a more upright back fin, that in most cases is larger than this fin. The WTF serves as the transitional fin in a reverse quad setup where it initiates turns and then transitions the turn onto the back fin. Amazingly, this fin works in an incredibly wide range of conditions and wave heights. It has been tested in everything from 3' faces to 25' faces, and it works through the whole range.

XTC-413, XTC-500, and XTC-450C

The XTC range currently consists of wide range of template sizes, but the two side fins shown here, along with the center fin, have been the most heavily used and tested this Hawaiian winter.

The primary driving force behind the design of these fins is to deliver a template design that behaves more like a wing than your typical "dolphin fin" style surfboard fin. The motivation for this design all started from the design of a tail wing for a foil board.

Like many modern wings this design features a tip extension to enhance the performance of the fin. This extension is flipped 16º to the outside and has a slight hollow foil on the inside face. The body of the fin also features a strong hollow foil. These fins are very efficient, fast, with a ton of drive. They also have the uncanny ability to help the board move through dead spots on the wave.

Due to their very upright nature they turn extremely well with out loss of speed through the turns. The tips play a crucial role in the turning process as they allow for transitioning of the fin during a turn. This means as the board is placed further on it's rail the tip of the fin becomes more vertical in the water allow it to create a pivot point. Hard to describe but something that can be easily felt when using the fins.

This pair of side being unmatched means they can be ridden either way in a quad setup, but in most of our testing they were ridden with the larger fin in the back. So they worked very well as a Twinzer setup. When coupled with a center fin either of these templates work really well, the smaller one for a very loose feel, or the larger for a positive feel in a wide range of conditions.

For thrusters two combinations can be created with the XTC-413 / XTC450C for a smaller looser setup and the XTC-500 / XTC-450C combo for a lot more drive and hold. Due to the shape of the center fin it has a lot of hold when positioned further forward while still providing great turning ability due to the more upright nature of the body of the fin.

These fins have been ridden in boards ranging from small fishes and kneeboards, through guns to tow boards. They have been successfully surfed in everything from 3' slop to 40' faces. They work!

The DS series currently consists of just this single template, it looks like a variant on a hatchet fin but there is a lot going on with this fin that is not apparent when viewing It from the side.

This design delivers a lot of drive and speed from a very small package. It is only 4" tall but due to the raked back shape it has a lot of pop out of turns and amazing holding power.

The unique thing about this design is the fact that the entire upper blade is flipped outboard by 6º and both the bottom portion of the fin and the upper blade have very string hollow foils. The combination of these features make this fin incredibly fast and effortless through turns.

By flipping the upper portion of the blade will gain a couple of critical performance enhancements. Firstly, it really helps the fin transition through a turn making the turns feel more fluid. Secondly, as the board transitions more onto the rail the upper blade becomes more vertical in the water, dramatically enhancing the feel in the turn. Essentially it makes it a lot easier to push off the fin in a turn. When coupled with the flex in the fin there is a lot of pop out of the turn for such as small fin.

The speed of this fin comes from the fact that it has a very low wetted surface, so this reduction in drag helps it go through the water a lot faster. Plus the hollow inside foils also greatly enhance the water flow over the fin, which really helps the speed.

Surprisingly, for as small as this fin is it works incredibly well as the side fin in a thruster setup, primarily due to the shape. On shortboards this fin rocks in a thruster setup when coupled with the XTC-450C center fin.

The latest generation of the Q family of fin designs. One of the most extensive range of templates in our HRD-KORE collection. The templates in the range enable a wide variety of fin combinations.

All of the Q2 templates feature our custom hollow foil technology on the inner face, which makes for a faster and more responsive fin! Smooth, powerful, high performance fins.

This range also includes a canard fin with an extra 10º of cant in the base, allowing it to be used with the Q2-XL to create an awesome twinzer setup.

The XPD2 quad range is an extremely functional family with different size combinations depending on the conditions and needs. These fins are ideal for quad setups as they feature good turning ability, plenty of drive, and lots of speed. Being an unmatched set the fins can easily be switched around as conditions warrant.

All of these fins feature our custom hollow foil technology on the inner face, which makes for a faster and more responsive fin! The unique outline keeps the base narrow for good turning, while the increased tip area provides lots of drive. The tips of the fins also feature increased toe-in to help with turning.

These are our goto fins for a wide range of boards and conditions. They have been successfully deployed on everything from 6-0 shortboards to 10-5 guns!

The WS2 series are a second generation version of our split keel design. These are also the first versions to be produced in our HRD-KORE RTM molding technique.

This series is made up of only two designs - a front fin WF2-S and a back fin WS2-L. The front fin features a flipped tip for better performance and transition speed. Both fins feature extensive hollow foils on the inside faces, again geared towards improved performance.

These fins can be used in a wide range of boards but are especially well suited to fish-style boards. When placed correctly these fins can provide an enhanced twin fin feel but without the twitchiness of the typical twin fin.

The design of these split keels depends for the best performance on the fins being placed as close together as possible. By this we mean the fore-n-aft placement. Because the fins are essentially a keel fin that has been split into two separate fins their functionality depends on a tight cluster.

However, this setup can still work really well in fin setups that are more spread out, they are just not as optimal as a tight cluster. These two different templates can also be used separately, although the design was intended to be used as a quad setup.

The A3 range represents one of our more conventional templates, all featuring a small cutaway at the bottom of the trailing edge. These fins feature good turning ability, lots of drive, and tons of speed.

All of the A3 templates feature our custom hollow foil technology on the inner face, which makes for a faster and more responsive fin!

These are very versatile and reliable fins that feature great performance.

The STD range of fins is geared towards a more conservative style fin than some of our other offerings. But these are still high performance fins that feature our hollow foil technology on the inside faces of the larger fins. These fins are derived from one of our oldest and well tested fin templates that has been optimized for todays high performance surfboards.

They feature a good balance between base width, rake, and tip area to deliver outstanding all around performance. Another unique aspect of these fins is that they feature a hand polished finish, something not commonly found in the fin market, they have to be seen to believed!

All of the fins in this series are only available in a SMOKE TINT.

The H3-S and H5-S templates are commonly combined with other templates to create quad setups. But these templates can be used by themselves, as needed. The H5-S is the latest generation of this Hammer design. It is used in combo with the A3-L, XPD2-L, and Q2-L to create even more powerful quad sets.

The H3 and H5-S templates are our more unusual shapes, but these really an amazing fins. They combine a very narrow base with a very large tip to generate a lot of flex that really pops out of the turns. Strictly designed to be used as a back fin in quad combos, they also makes excellent side bites in 2+1 setups, as long as there is no kelp in the area where it is being surfed!

The H3-S has a flat inner face, while the H5-S features our unique hollow foil on the inner face. The H5 has slightly more area than the H3 with a little less rake. The latest generation.
