KS3 SAIL

Championship-Proven Wave Sail – Now with Revolutionary INSIGHT® Vision Window

Developed in 2013 by Kauli Seadi, Jeffrey Henderson, and Tom Hammerton, the KS3 has consistently proven itself as the undisputed finest and most respected 3-batten wave sail. Considered by many as one of the best wave sails regardless of the number of battens, the KS3 has won many of the Aloha Classic contests in the pro division. In 2022, it won the first PWA wave contest in Cape Verde with Bernd Roediger beating the world's best on his KS3, and in 2024, he took first place again in the Japan World Cup. It is the only 3-batten sail proven to perform amazingly at the highest level of wave riding, and many have found it to be the best down-the-line wave sail in the world.

Explosive Response, Rock-Solid Stability

The KS3 is the most stable and direct sail in our line. It is powerful yet unbelievably stable, thanks to the three-batten design, which has radically less sail momentum, leading to faster response times and improved feel. The result is a more explosive wave ride and quicker action in the air. For those not in the waves, the KS3 is an amazing sail that seemingly does not get overpowered and maintains a locked-in feel under all wind conditions.

Game-Changing INSIGHT® Vision Window Technology

The new C2 color features the latest version of the KS3 with our revolutionary INSIGHT® Vision window that stays clear and can be cleaned for the life of the sail. This stunning window opens all the way to the mast, providing extreme vision while riding. Unlike traditional monofilm, which scratches and clouds over time, the INSIGHT® window will never scratch and can be cleaned to a clear finish for years.

The experience of wave riding with virtually no visual restrictions makes this feature a dramatic improvement. It is helpful even on flat water while making jibes. It makes other maneuvers so much easier by having more visual peripheral perception, which improves your balance. This is the most significant change in the KS3 since its inception.

Built to Last in the Harshest Conditions

We've reinforced the foot area with SPIDERwebbing® ripstop and added a new top chafe pad made from our recently improved lightweight ROX Webbing. The ROX material sleeve is so tough that it will resist even a broken mast!

Our ballistic batten SuperSkin® is used on all 8mm and mini battens. This skin adds structure and helps contain batten breakage, allowing for mess-free replacement with no sail damage.

Experience the sail that's redefining what's possible in wave riding—the KS3 with INSIGHT® Vision – where championship pedigree meets revolutionary innovation.
