RDM Reduced Diameter Mast

99% Carbon. Made in the USA. The 99% flatwater mast is designed from the highest grade carbon available, period. Don‘t mistake it for helium though, it‘s just carbon, nothing but carbon.

Designed for Freestyle, Race, Freeride and Freecarve, this flatwater mast has the fastest reflex response of all Goya Windsurfing masts, giving enormous amounts of acceleration to any sail you rig on it. Especially the Bounce Pro Freestyle sail comes to life like no other on this mast. The 99% is your choice if you are looking for unsurpassable performance period. Precision engineered. It’s center of gravity is beautifully low and its weight is among the lightest on the market.

With that comes an obvious amount of delicacy, hence we recommend you do not take this mast into the waves and advise you to take special care when rigging in rough terrain.

Available in 340, 370, 400, 430 centimeters.

Comes in Diagonal Flex™ technology.
Peel Ply anti-slip boom area prevents sliding.
Built with same length sections for easy handling.

Hey guys!

How's life!? Quick email to say how fantastic the 99% masts are. They make the rig feel so much better but at the same time the same:

1) obviously lighter (less swing weight in the top) and lighter is always better.

2) greater wind range, especially top end, but the low end feels way more direct: instant planing

3) in moves we feel they provide more lift: bigger jumps, more air, faster rotations!

4) better control in (freestyle) maneuvers: it's as if the sail is more often in the right place and letting you do what you need to. The rig has less a life of its own so to say.

Yep, superstoked with them 🙂

Question: can these mix and match with the regular masts? Say have a 99% top with a 90% bottom or vice versa?
