Changing your fins is one of the quickest & easiest ways to improve the performance of your board, & increase your surf stoke!
FCS thruster and quad sets are categorised by size.
|Optimum Weight Range under 120lbs / under 55kg|
|Optimum Weight Range 120-155lbs / 55-70kg|
|Optimum Weight Range 140-175lbs / 65-80kg|
|Optimum Weight Range 165-200lbs / 75-90kg|
|Optimum Weight Range over 190lbs / over 85kg|
|For specific surfboard designs or as specialised fins|
How Fin Materials Can Improve your Surfing
Most FCS fins are constructed of either Ultra Light, Performance Core, Performance Glass or Glass Flex material.
|Performance Core Carbon (PCC)
Performance Core construction with hand laid carbon fiber designed to deliver controlled flex and enhanced base stiffness.
|Performance Core (PC)
Performance Core material and construction is designed to deliver the feeling of a traditional fibreglass fin with the added performance of reduced weight. The RTM (Resin Transfer Moulding) process produces a lightweight fin with remarkable flex, a smooth feel and an impressive aesthetic.
|Performance Glass (PG)
Performance Glass material characteristics and flex pattern are identical to traditional fibreglass fins offering a stiff base with subtle responsive tip flex, amazing aesthetics and proven durability. PG fins are the perfect transition fin for surfers moving from fixed fins to the convenience, accuracy and performance of FCS.
Lightweight, moulded fiberglass construction delivering pro standard performance. The high fiberglass content makes these fins stiff and responsive, and the engineered foils provide a consistent feel in a range of different conditions.
|Glass Flex (GF)
Glass Flex has been formulated to replicate the flex and memory properties of hand layed fibreglass. It’s advantages over other composite fin materials include stiffness, a more positive flex pattern (nice tip flex, little base flex) and remarkable flex memory. The precision of the injection moulding process ensures the highest accuracy in geometry in each fin produced.
Understanding FCS Fin Characteristics
All FCS fins are classified by the following characteristics; Base, Depth, Area, Sweep and Foil.
Understanding how these fin characteristics can change the performance of your surfboard is an important consideration when working out which FCS fins are best for you. Each of the following fin characteristics are clearly listed on each each fin page, allowing you to evaluate the impact that a fin design would have on your surfing.
Base is the length between the leading and trailing edge where the fin meets the board. Base is primarily linked to drive. Fins with a longer base will offer substantially more drive and acceleration.
Depth is the distance the fin penetrates into the water. Depth directly relates to hold. The greater the depth the more hold, the shorter the depth the more a board will slide and release.
Area is the total surface area of the fin.
Sweep is the angle measuring how far the outline of the fin is curved backwards; also referred to as rake. Sweep has a direct influence on pivot. Fins with more sweep produce a longer turning arc, less sweep offers a tighter turning arc.
Foil refers to the shape and geometry of the inside and outside faces of the fin. Foils directly affect the flow of water over the surface of the fin. Different foils create variations in water flow and have a direct link to the overall performance of the fin and the board.
|FLAT FOIL: A flat inside face combined with a convex outside face. The traditional flat sided foil offers an even combination of drive, pivot and hold and provides a very consistent, reliable feel over a wide variety of conditions.
INSIDE FOIL: A sophisticated hydrodynamic foil consisting of a convex outside face, a rounded leading edge and a concaved inside face. Inside foil increases the efficiency of water flow over the surface of the fin adding lift and reducing drag. The result is a fin with more options through increased hold and speed.
50/50 FOIL: A symmetrical foil used on all centre fins where both sides are convex. Even water flow on both sides creates stability and control.
70/30 or 80/20 FOIL: Combines the performance of a centre and side fin offering increased speed, smooth rail-to-rail transitions and a consistent feel in a variety of conditions. (Ideal for all board types and rear fin placements)
