Design and Feel

The fin is constructed out of FCS Performance Core material.  This material makes it a very lightweight keel fin with excellent flex.  This is the same material that the FK-2 fin is design with.

The FK-1 fin features a base of 7.00" (178mm) making its fin base 1.51" smaller than the traditional FCS Fish Keel Fin.  It however has the same fin base size as the FK-2 fin.

The fin also has a depth of 5.06"(129mm) and a total area of 26.15"2 (16868mm2). It features a sweep of 32.9 degrees.  This makes the FK-1 a deeper, more upright fish fin than both the traditional FCS Fish Keel Fin and the FK-2 fin.

The FCS FK-1 fin is also a very stiff fin, stiffer than the FK-2 fin, but with similar flex to that of the Traditional Fish Keel fin.

A big difference between the design of the FK-1  and the other two fish keel fin templates is that this fin features a symmetrical 50/50 fin foil as opposed to a 80/20 foil.

This means that the FK-1 is convex on both sides allowing for even water flow across the fin providing stability and control.

The Look

This FCS fin is red in color and has FCS FK-1 stamped in white at its base. The FK-1 fin also features the internal honeycomb, hex pattern, due to its Performance Core, construct and has 3 fin tabs for increased strength.

What We Say

This is a great fish keel fin for those surfers who need a removable keel fin but want to keep it simple and effective.

The fact that FCS has created this hybrid template from a mixuture of popular fish keel templates means that you will get the best of the best with the FK-1.

Also featuring the Performance Core and 3 tabs makes it a very light and strong keel fish fin.  If you are a medium to large sized surfer and you want to add drive and carve to your retro fish design then this fin should work for you.
