Hundred Pro

RDM Reduced Diameter Mast

100% Carbon. This all new all carbon mast is our pride and joy. We’ve put years of research into this mast, to deliver a product that surpasses our previous all carbon Flatwater mast in both performance and stability. The goal was to open the new product up to all disciplines. Where our previous mast was limited to Freestyle and Freeride, the new Hundred Pro feels equally at home in Wave and Race, and delivers insane dynamics. The reflex of this mast alone will transform your entire rig, both by the Direct Drive™ and Diagonal Flex™ technologies it incorporates, but also by it’s sheer difference in weight. This is our new lightest mast, and for many team riders it’s their new favorite.

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.

All Goya Windsurfing RDM masts are now interchangeable, all lengths, all carbon contents. (Except Ninety Pro)

Hi Francisco,

Thanks for getting back to me, the mast is a gaastra 75% rdm, not sure what year, it's silver with gold colored reinforcements... it does seem to work pretty well on my Banzai, so shouldn't be too extremely hardtop right? Sending you a picture could be a good idea, you can judge the shape/tuning with this mast hopefully... again, thnaks for your answer,

Regards, Alwin.

Hi Alvin,

My pleasure. Yes, a picture is always helpful.

You don't want masts with a soft bottom, or stiff top. This makes the lower two battens disengaged. When you downhaul, the sail/mast folds in the middle, and the lower leech is the one that opens up. All the forward drive, reflex, and acceleration are removed from the profile, making it feel heavier at the top.

Please let me know when you are in the market for a new or used mast. We will be happy to provide you with some options. Here I also cc Pascal, who manages our shop on Maui.

All the best!

Very please with these! I was surprised by how light they were and worked really well with the smaller rigs.

The smallest masts are often disappointing in range since they are often just a ‘sawn off’ version of the larger size but these are excellent!

I finally got out the gear yesterday at Doug's. I am blown away! The Banzai X 3.4 with the 100% 370 and skinny boom felt like a butterfly's wing in my hands! And the Cube 81 turned so radically I actually tripped over it when I carved hard upwind for a backside hit! Now I understand how MB makes those crazy turns.
