ACK

Another test winner in 2015 and 2016, which goes totally into the racing direction. Take all the goodies from a full on competition slalom sail, put them into a manageable package and you’ve got the AC-K. Featuring a medium sized luff pocket, a sweet smooth rotating 3-cam set-up combined with a lot of low-end power to get planing nice and early. The AC-K is a high-speed powerhouse that is easy to handle and sits ridiculously light in your hands, keeping  the board at a steady hover above the water to give you the best possible control and speed out of your kit.

Check out the new mast sleeve construction and you will smell the art of racing, deriving even morefrom the AC-1 race sail line. Featuring some new development steps that will also be found on the 2016 version of the AC-1.  We always develop by comparing the differences between the AC-K and AC-1, and decided to reduce the differences and get the sails even closer to each other in terms of performance, keeping in mind that it needs to stay a user friendly sail.

We have worked on each detail by taking each size separately so that  according to the conditions, each size can offer either more power in light wind sizes or extra comfort in smaller strong wind sizes: outline and leech twist, materials in the mast sleeve and body of the sail. The wind range, stability and smoothness of each size is nothing but spectacular. A negative leech reduces drag at higher speeds and gives a reduction of backhand pressure in higher winds. The top of the sail has a smaller head for more stability in stronger wind and in the boom area more S-shaping continues to boost the overall acceleration in the sail. Xply batten pockets for lighter weight and reflex.

It’s amazing fast, so it’s less to be surprised when we saw it as a test winner on Planche Mag in 2015 and 2016 again. We really pushed the development of this sail and have left no gaps. We ride it with our full slalom boards, and fins, to feel each corner of the sail and work on it to make it go better and better. We are being selfish to want our windsurfers who chose this sail to be the fastest on the water. Enjoy being kings out there!
