K9 Series
The latest generation of our family of keel designs - K9! This fin is also used in the K9/PWR combo. It takes our original KCS keel fin and updates it with several improvements.
The overall base length has been shortened to reduce tracking, but the most significant change is the introduction of the KAHI (cutaway). This reasonably extreme cutaway helps loosen up the design while leaving the fin with plenty of drive. In addition, by reducing the base length and adding the KAHI, we reduce drag, making the fin faster.
As with most of our new designs, these fins have PHAT FOILS and HOLOFOILS on the inside faces. The trailing edge of the fin is also cambered to help focus the water flow through the center of the fin.
These fins work very well and are an excellent choice for a twin fin, in larger sizes, and also for fishes, where they can be combined with the PWR fin for an even more powerful setup.
K9 Series Details
Currently, the K9 series is only made in three sizes, all with KAHI's. As shown in the K9/PWR combo, the middle size is used.
The larger version is used for twin fins and fishes, and the smallest version is best suited for a smaller combo with the PWR back fin or possibly as a side fin in a thruster setup. It could also be combined with a different template in a quad setup.

K9 Fin Combinations
The primary combo for this fin is shown in the K9/PWR section. Otherwise, these fins are meant to be used by themselves.
Additional combinations could also be created by mixing them with other fins.
F8 Series
This is the latest series we have been working on. It is loosely based on the DV9 design but with the added tip extension. Most of the designs in this series feature a slight flip in the tip as well, called the FLIPTWO.
This new design is a high-performance fin that handles various conditions. It features our PHAT FOILS and HOLOFOILS, with the FLIPTWO allowing for more efficient HOLOFOILS. In addition, extending the tip gives the fin a lot more feel later into the turn while also providing a better pivot point.
The main body of the fin is more wing-like than the typical fin and allows the fin to be very efficient at generating lift and thereby creating forward momentum.
Due to how the FLIPTWO is implemented, the fin profile features a distinctive taper from the base to the transition to the flip. The FLIPTWO is, in turn, a lot thinner than our first-generation flips. We are minimizing the risks of cavitation. There is also a slight hollowing of the inside face of the flip to give it a little more bite in a turn.
Two dedicated center fin designs feature even more prominent tips to give them greater holding power and feel in the water. In addition, these center fins have very distinctive foils that differentiate between the throat and blade of the fin.
F8 Series Details
Currently, the F8 series consists of seven sizes of side fins, most with FLIPTWO tips.
The wide range of sizes makes selecting an optimal quad, thruster, or twinzer setup easy. Two separate center fins can be used to set up the thruster setups.

F8 Fin Combinations
Given the wide range of sizes in this series we could not crreate all the possible combinations, but these are the standard ones.
Additional combinations can also be created by mixing them with other fins, some of which are also shown here.
