FCS II H4 Fin

Unique shaped fins that are finished beautifully. I enjoyed how light the fins are, yet are incredibly strong and stiff. The fins are responsive and create super speed and drive out of turns. This is the best set of fins I have used in 26 years. In fact, they've given me so much stoke, that I have purchased a second set, to enjoy the medium and large sizes for different size surf.

Nothing about the design of these fins has been overlooked, the material is of a very high quality and the design seems to have been developed by NASA. Speed ​​and control!!!

From the first wave felt the immediate boost in speed. Like them so much that I have shifted from 2+1 to h4 thruster.

Great fins

The H4 fins are a pretty fast fin template. Acceleration is immediate along with immediate response. These fins work great in most average short boards or fishes with moderate to low rocker.

However very sensitive ultra high performance shortboards with heaps of rocker such as the lost whiplash I would not recommend this fin. Using it on a board like this would cause the board to surf too sensitive hence a lack of control which leads to choppy poor surfing style. With a very high rockered board I’d stick with the Channel Islands fin template which offers a great amount of speed and smooths out the ride in ultra sensitive shortboards. I myself however prefer the Channel fin over the H4 because the Channel Islands releases off the top a lot easier due to the smaller middle fin and tapered tips. The H4 I felt would stick to the lip a little too much when trying to blow the tail sometimes. The H4 however surfs as a faster reacting fin to spice up less sensitive lower rockered slower responding shortboards. I’m definitely going to use the H4 fins in my fishes and standard lower rocker shortboards.
