The Strongest Mast We Have Ever Made – Proven Over 10 Years

The KAULI 90% carbon RDM mast is the strongest mast we have ever made. A slightly flexed top mast perfect for the KS3 and all our wave sails, the Kauli is the toughest. In the 10 years we have supplied it, we have had a failure rate of less than 0.5%, and most of these failures were on the rocks at Hookipa or the one that broke when Z crashed at Jaws! Kauli has never broken one, and he does not hold back. This strength is worldwide!

Proven Solid Beyond Our Expectations

Now in its fifth year of production we have such a low failure rate that this mast is proven solid beyond our expectations. If you are pushing hard, maybe too hard, this is the mast you need.

Ballistic Fiberglass Protection Over 100% Carbon Core

The Kauli is basically a 100% carbon mast that we then wrap in ballistic fiberglass prepreg to protect against direct impacts from rocks, reefs, and other hard objects that can occur in extreme conditions or during extreme travel.

The Best Choice for Strength and Reasonable Weight

If you want the best strength-to-weight ratio, the Kauli is your best choice!
