All FCS fins are classified by the following characteristics; Base, Depth, Area and Sweep.

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. 

BASE
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
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.

SWEEP
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.

AREA
Area is the total surface area of the fin.
