These ratings are to compare k4fins only. Our fins are lighter, looser and grippier than anything else on the market with test winning performance. This guide will help you dial in your board for ultimate performance. RELEASE/GRIP: This is a choice you have to make. Do you want to do huge wrapping gouging roundhouse cutbacks with ultimate grip, or would you rather the tail spun more easily into a Taka? Size choice will also affect release. LOOSENESS/CONTROL: Again a personal preference as to wether you like your board to feel loose and skatey, or more directional and planted. SNAP/CARVE: Snap and pivot for tight 'in the pocket' surfing, or carve for more drawn out turns on open faces. This is related to looseness/control but more to do with template than flex. LOW DRIVE/HIGH DRIVE: Your immediate thought might be that the more drive the better, right?! Not always the case. Quite often on multifin boards you'll find yourself flying up at the lip but without the ability to get the board turned, this is too much drive.
Our original fin for performance wave riding. Lots of flex for amazing grip and looseness on the wave. Raked template for control. A progressive foil for different flows between tip and base. Test winner. Will loosen up a 'stiff' board and are particularly sweet as twin fins as they eliminate that unwanted top turn spin out.
Sizes 12-17cm US SLOT heads.
Our stiffer and larger area line of fins. Great for heavier riders applying greater power in high wind and wanting more drive in low wind. Also suitable for lighter riders in onshore conditions or for those wanting more 'release' to learn taka's and other wave/freestyle moves. Upright template gives better 'pivot' for in the pocket riding.
Sizes 16,18cm US SLOT heads.
I've included the Stubby again in a smaller size so it's easier to compare the template with the other possible front options of SHARK and CARVE. Ratings are given as a front fin rather than rear. A great front fin choice for riders wanting maximum area and hold. Works well for all fin configurations.
Sizes 8,10,12,13,14cm US SLOT MT heads.
Our front fin for looseness and speed. If you're getting all the grip and drive you need from the rear fins, this is a great front fin for loosening up your quad. Test winner.
Sizes 6,8,10cm all heads.
Our front fin for drive and control. Great for big sweeping carves and gouges. Swept flexy tip for maximum grip, high rake for control and wide base for drive.
Sizes 12,14cm US SLOT MT heads.
The Ezzy Asymmetric fin! More power, more drive, more speed, less drag. This fin has a similer template to the Stubby but with an even wider base. Fully asymmetric foil with a radiused front and slightly positive inner foil to aid flow at high speeds. Choose a smaller fin size for less drag, same power. Great for huge gouging hooky cut backs.

Our Freestyle fin developed by Andy 'Bubble' Chambers. We originally had two very different prototypes; one worked great on flat water but would spin out in the chop, the other was rock solid in the chop but too grippy on flatwater. The BUBBLE freestyle fin has the perfect blend of grip to be secure in the chop and into carving manuevres, whilst still allowing plenty of release for double spins.
Sizes 14,16,18,20cm US/POWERBOX.
Ignore the ratings! This is a fin designed to get you over 50knots and has the worlds fastest 2 second max to prove it! 50.48 knots and number one spot on the 2 second gps ranking. Very very secure in the chop. A thin carbon foil with minimal drag.
As Jon Kennet from MOO CUSTOM would say 'it stops the back overtaking the front!'
