Ultra Pro RDM
Our Lightest Flatwater Mast
The Ultra Pro is the lightest mast we’ve ever built—designed specifically for Foil, Freestyle, Racing, and Freeride disciplines where weight, reflex, and balance are everything. At just 1.3 kg for the 400 size, it practically defies gravity. Riders often say it feels like cheating—the sail stays up effortlessly, letting you focus purely on performance.
Use with care. This mast features a thinner wall to minimize its weight. It is not intended for wave conditions, surf impact, rocky environments, or shore break. Any damage from those conditions is not covered under warranty. Always handle with caution—avoid contact with sharp edges or hard surfaces.
This is the mast for those who demand nothing but the lightest, fastest response on flat water or controlled conditions.
Not All Masts Are Created Equal
On paper, many masts might share similar specs—constant curve, matching IMCS, bend percentages, or comparable weights. But true performance goes far beyond the numbers.
What sets Goya masts apart is consistency, from premium materials to precision engineering. We use only Toray prepreg carbon fiber, the global benchmark in composite performance. Unlike many prepregs made in-house without environmental controls, Toray’s prepreg is cured under precisely regulated temperature and pressure, with exact fiber-to-resin ratios. The result is Direct Drive—a fast, clean reflex that loads and releases with exceptional control. Because performance isn’t just about how a mast bends—it’s about how quickly it recovers, delivering what we call true IMCS.
Interchangeability Built In
Goya masts are designed for real-world versatility. Tops and bottoms are fully interchangeable—not just within the same size, but across sizes. Need a shorter top for a smaller sail, or a longer bottom for more low-end power? Just swap the section. You can also fine-tune bend characteristics, reflex, and overall weight by mixing different carbon content models. A truly customizable system—tailored to how and where you sail.
Built for Real Conditions
Most masts perform well in a controlled lab. But real conditions—surf, chop, gusts, and wipeouts—bring twisting and diagonal forces that reveal the difference. That’s where Diagonal Flex™ comes in.
This engineered flex pattern allows the mast to bend deeply and twist dynamically under pressure, staying lively and in control. Developed in synergy with Goya sail design and materials.
Experience the Difference
Every detail is considered—from the peel ply boom grip to precision ferrules that prevent sand lock. Backed by over decades of design expertise and testing across the globe, this is a mast built to perform.

The One Piece That Transforms Everything
If there’s one item that can elevate all your gear and your entire windsurfing experience, it’s the Ultra Mast. Yes, a single piece of equipment can completely transform how your rig feels—lighter, faster, more responsive.
But with great performance comes responsibility. The Ultra is not designed for every condition. It should only be used when the waves are small and there's no shore break. This is a precision tool for ideal conditions—not for heavy surf or rocky environments.
That said, if you're ready to take your sailing to the next level, just try the Ultra. Once you feel it, you won’t be putting the genie back in the lamp.

This is the handling with 430 xo sail..it is a ccwith few flex
.top is modereting open.
Aloha Jean,
This mast is slightly softer at the bottom and stiffer at the top.
This reduces the outhaul range, as the sail becomes flatter around the boom area while making those two lower battens sit further away from the mast.
While riding, you will see more wrinkles around the boom area as the tension at the bottom of the sail decreases while the top of the sail increases, reducing the upper leech opening/twist.
Not terrible, but it’s not ideal. If this is what you are seeing and feeling, and if it is a possibility for your budget, then it would make sense to use our mast; it would not only make your Nexus sail perform at its best, but it will also be the same as any other sail out there.
All the best,
Francisco
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!
