Seventy

RDM Reduced Diameter Mast

70% Carbon – Performance for Everyone
Our new 70% carbon mast delivers high-end performance with accessible durability. It’s lighter and faster than many higher-carbon alternatives, offering a responsive, lively feel that brings out the full potential of any sail. Whether you’re progressing, rigging daily, or pushing your gear in real conditions, this mast meets you there.

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 Seventy 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 teams in the world.

Experience the Difference
Every detail is considered—from the peel ply boom grip to precision ferrules that prevent sand lock. Backed by over 30 years of design expertise and testing across the globe, this is a mast built to perform—and built to last.

It may just be the last mast you’ll ever need.
