The FCS 2 Twin And Keel Fin Range

The twinnie is back

The twin fin has had a resurgence of late & with summer now in full force, what better time to get clued up on the FCS 2 Twin Fin range. The fast, loose feel of a twinnie will put a grin on your face as you glide & slash your way through that 2ft summer slop. 

Below is a bit more info on both New & Classic FCS 2 Twin Fin sets to help you match the right fin for your board, Plus a few clips of twin fin inspiration for you to froth over.

FCS 2 MR PC Tri Set

This fin is an absolute classic. Mark Richard’s won four world titles from 79 to 82 on this fin & it’s been around ever since. This template produces exceptional drive and speed. 

The small stabilizer (centre fin) adds control whilst maintaining the freedom and manoeuvrability of a twin fin set up. It works well in a variety of board types, especially the round nose fish from …Lost. 

A great fin to try if you’re new to twins.

FCS 2 AM Twin Set

Al Merrick has taken his immensely popular tri fin template & adapted it for twins. Increasing the size of the side fins & adding a mini stabilizer for the centre fin. 

The low sweep (rake) and narrow tip means these fins pivot and release exceptionally well, while maintaining incredible trim speed and the ability to quickly break into a turn. Mini stabilizer has a narrow, elongated template with a rounded tip to add control when driving through turns. Another great all round twin template for most.

FCS 2 Power Twin Set

The New Power Twin is a great fin for the big boys or those of us that like to throw a bit more into turns but still want that twin fin speed & flow. Designed in collaboration with Harley Ingleby for use on his asymmetric twin model, the Power Twin has the highest area in the FCS range; as a result, can be pushed harder through turns.

It features a moderate sweep (rake), full tip and longer base delivers incredible drive and speed yet its lower depth value maintains manoeuvrability and looseness off the top and through turns.

The first of two new keel fins from FCS keeps it old school. Performance Glass (PG) construction gives the look & feel of a traditional glass-on keel fin. 

It has a lower area than the Modern keel, making it feel fast & loose (as any twin should) while encouraging a more progressive & radical approach to riding a fish. Or you can just take a high line & trim cause that’s pretty fun too.

An updated keel template for today’s fishes. More upright that the Retro Keel & less sweep (rake), the Modern Keel will pivot in a tight radius. High area and depth not only delivers a feeling of control when pushed harder on the open face, but helps to maintain tremendous speed through roundhouse cutbacks. The base of the fin is also tapered towards the back to decrease drag & turbulence. 

Bryce Young rides a variety of boards in this clip including keel fin fishes & some freaky looking twin + stabilizer asymmetric boards.

While this fin set is technically a quad, it takes the idea of the traditional keel fin & splits in two. Designed by Matt 'Mayhem' Biolos of …Lost Surfboards, this fin adds bite and control to modern fishes & hybrid boards with wide tails, without sacrificing pivoting capabilities or speed.Not to mention it looks crazy.
