Premium Quad SUP Fin Set
This is a top of the line quad fin set-up by FCS for stand up paddle boards. Its a set of 4 fins, 2 PC-7s (performance core fins) upfront and 2 GX-Qs in the rear. The combination makes for superior all around stand up paddle surfing performance.
About Quad Fin SUP Set-ups
This premium FCS quad fin SUP set-up features two sets of twin fins. There is a larger set of fins in the upper outside position followed by two smaller side bite size fins on the inside set back further on the board. The concept here is that they are using more, smaller fins to compensate for the lack of a deep center fin. The result is you still maintain control, yet you get rid of the drag created by the larger center fin a faster stand up paddle surfing experience, yet not squirrelly. In the surfboard world this is a common fin configuration for big wave surfers as when the board is riding heavily on one rail you still have two fins plus the edge still helping maintain stability and control.
About SUP Fin Selection
Whether you stand up paddle board on flat water exclusively, or stand up paddle surf exclusively or somewhere between the two, its a good idea to give some thought as to how SUP fins might be able to improve your performance and enjoyment. In flat water SUP paddling, the most important thing paddlers are looking for is better tracking and stability. If you dont think your SUP fin choice matters, try removing the fins some time and see how miserable the experience becomes. On the other extreme spectrum of the sport in standup paddle surfing, SUP fin choice is perhaps even more important as paddlers are looking to improve speed down the line, the feel and feedback thru your turning arc, rail-to-rail transitions, stability in turbulence, and even SUP nose riding. With removable SUP fins, you can change your set-up for different uses such as flat water paddling one day, SUP surfing the next, and SUP downwinding the day after.
When it comes to SUP surfing, there are a dizzying array of SUP fin configurations to choose from including a longboard single fin set-up, a classic 2 + 1 SUP fin set-up, a thruster fin set-up (also called a tri-fin set-up), a twin fin set-up, or a quad fin set-up. Not all boards allow the flexibility for multiple fin set-up configurations (high-end standup paddle surfing boards typically do), so your choices might be limited in some cases.
The bad news is that many new SUP boards (especially in the lower-end of the market) come with pretty basic low-performance fins just thrown in as an afterthought. Its worthwhile considering an SUP fin upgrade. Often times with one small change, you can dramatically affect the performance of your stand up paddle board.
FCS, which is an acronym for Fin Control System, is the pioneering company in removable fin systems. Before the 1990s, most surfboard fins were an inseparable component of a surfboard. The fins were glassed right to the board. There were removable fins as far back as the 1960s, but it wasnt that common and there was no standardization so things werent really interchangeable. So to a larger degree, whoever was manufacturing the board was also making the decision about fin configuration and fin selection. FCS came along in the early 1990s and separated these three pieces by creating and popularizing a standardized FCS fin box. Suddenly board manufacturing and fin choice and fin configuration selection were largely separated.
FCSs standardization of fin boxes made removable fins commonplace. This changed a number of things. First off, it allowed for massive advances in fin design and performance as companies were tinkering with new materials and various designs. Secondly, it allowed surfers to use one surfboard (the control factor in this experimentation) and change their fin configuration to find out what they liked best. They could even use different configurations for different conditions. Lastly, it made surfboards far easier to transport with the fins removed, which was no trivial event. Manufacturers and retailers were able to store and transport boards much easier, and with much less risk of breakage.
In large part due to FCS, the variety of fins available is almost overwhelming and surfing performance has made great strides. The market for SUP fins is really just in its infancy (as R&D production cycles can be years in the fin industry), but be sure that FCS fins will be at or near the forefront of what is to come in the advance of SUP fin design.
