Hot Sails Maui - Windsurf sail

The KAULI 90% carbon mast is the strongest mast we have ever made. A slight flex top mast perfect for the KS3 and all our wave sails the Kauli is the toughest. In the 3 years we have supplied it, we have only had one mast break each year! Kauli has never broken one, and he does not hold back. This strength is worldwide!

With sailors all over the world sailing to extremes and only have 4 failures is a near miracle of strength. The Kauli is basically a 100% carbon mast that we then wrap in ballistic fiberglass prepreg to protect against the direct impact of rocks, reefs, and as any hard impacts than can happen in extreme conditions, or extreme travel.

If you want the best strength, with reasonable weight, the Kauli is your best choice!
