1. Keyless

Efficient keyless system for quick fin installation and release.

The FCS II system requires no grub screws or keys to secure the fins to the board.

Fins can be easily inserted and removed in seconds, allowing you to adapt your equipment to the conditions, on land and in the water.

2. Flush Leading Edge

Recessed leading edge with flush base connection improves water flow.

These features not only create a sturdy anchorage to the board, but minimize water disruption through a more flush and seamless transition between the fin and board surface.

3. Backward Compatible

 

The FCS II System is backwards compatible with all your favourite FCS dual tab Fins.
 

4 - 5. The Mechanism

Constructed using a corrosion resistant titanium tension rod, and a rotating, wear-resistant polymer barrel


When the fin is inserted into the plug the barrel interacts with a groove detail in the fin to lock it into place using a combination of downward and lateral force.


The FCS II Fin System has been tested to over 4,000 cycles (installing & then removing the fin). Under normal conditions, the FCS II system will outlast the life of the board.
 

6. Honeycomb Construction

Lightweight Composite Frame encapsulated by high density foam reduces weight and maintains flex.

 FCS II FAQ

Will the FCS II mechanism keep working over time?

The FCS II mechanism will continue to work no matter how many times you change your fins. This simple, but well refined mechanism constructed from superior materials ensures operational longevity.

FCS has completed repetition testing (installing then removing a fin from the system) with no retention force lost over 4,000 cycles. Under normal conditions, the FCS II system will outlast the life of the board.

Will fins eject out of the system unintentionally when surfing?

The FCS II system has a high fin retaining force (around 12kg/26Ibs) and fins cannot be removed from the system by placing force on the front or side of the fin (i.e. the direction of forces applied to the fin during surfing). A fin can only be removed from the system by applying an upwards force to the rear of the fin.

Will sun and salt water corrode the FCS II mechanism? And how about if sand enters the plug, will it jam?

The FCS II mechanism has been designed to operate in a highly corrosive environment. All materials used to construct the FCS II plug have been selected for their anti-corrosion properties; including titanium which is an inert material (will not rust). If sand enters the plug, the mechanism will not be restricted and will flush out the sand through the open slot cavities.

Will my old FCS (dual tab) fins work with this system?

Yes, you can use all your existing FCS fins with the FCS II system. The FCS II plugs are backwards compatible - grub screws can be used within the FCS II plugs to secure your existing dual tab FCS fins.

FCS has designed a set of unobtrusive silicone infills to fill the gap created by the old fins in the new system. The infills are made from high quality silicone rubber which will not damage the plugs or fins. They are also extremely durable, light and built to withstand extreme temperature and corrosive conditions. The infills replicate the flush leading edge of the new fin design improving the performance of the old fins.

good water
Size: 16.9 Fl Oz (Pack of 12)
I like to taste of this water And I feel like the quality is good. the size of the bottom is perfect for on the go. the water quality is good and it is refreshing. the water doesn't have a bad after taste. The only drawback would be the bottles are a little thin and you have to worry about the durability of them if stacking in the fridge because they could open from pressure. The durability of the bottles are lacking s bit.

Clean, easy drinking water with a mild taste
Size: 16.9 Fl Oz (Pack of 15)
This bottled water has a clean and mild flavor that makes it easy to drink throughout the day. It is light and refreshing without any strong mineral aftertaste, which keeps it simple and consistent. The bottles are convenient for carrying around, and the 15 pack is practical for keeping stocked at home, work, or in the fridge. They are easy to open and store without taking up too much space. I like that the taste is consistent across bottles and works well for everyday hydration without any added flavor or heaviness. One thing to keep in mind is that it is a very basic bottled water option, so it stands out more for convenience and consistency rather than anything unique. Overall, this is a reliable everyday water choice that is simple, clean tasting, and easy to keep on hand.

Cheap and delicious water.
Size: 16.9 Fl Oz (Pack of 12)
Delicious! I can't stand some bottled water like Dasani, but once I got it ice cold, it's really nice. Bottles arrived in perfect condition with no leaking.
