RDM Reduced Diameter Mast

The all-new Hundred Pro is our pride and joy—a full carbon mast that elevates any rig, across any discipline. Years of development went into this mast to deliver unmatched performance, responsiveness, and stability.

Whether you’re riding waves or chasing speed, the Hundred Pro brings an insane dynamic feel. Its lightning-fast reflex—powered by our Direct Drive™ and Diagonal Flex™ technologies—transforms the entire rig. And with a significant weight reduction, the handling is simply next-level.

This is our new flagship mast—built for wave, freestyle, freeride, and race— becoming the favorite choice of our top riders.

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 even in the most critical situations. Developed in synergy with Goya sail design and materials, it’s the foundation of the Hundred Pro’s power and precision.

From gear that stays rigged all season at centers, to the world’s most demanding wave spots, Goya masts are tested to the limit. They’ve earned a reputation for performance and reliability—with one of the lowest breakage rates in the industry, and the trust of one of the largest wave teams in the world.
