Goya Eighty Pro 80% RDM Windsurfing Mast
Eighty Pro
RDM Reduced Diameter Mast
80% Carbon – Strength, Lightness, and Feel Our strongest mast is now lighter than our previous 90% carbon model—and quicker, too. With an incredibly responsive feel, it has become the team’s go-to choice in overhead waves and for withstanding the rigors of travel. The perfect balance of durability, reflex, and weight.
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.

STIX Boom Bra Board Protector with String
TSL 60% Carbon RDM Windsurfing Mast 450cm ONLY (25 IMCS)
Probably the best selling mast brand in the UK for decades,Tushingham have updated not only their graphics but also their flex characteristics to make them compatible with the widest range of sail brands available.
The quality and heritage of production remain the same, the flex characteristic changing to constant curve - and if you have Tushingham rotational sails , don't worry , your sail will still feel good rigged with the new models.
The CARBON 60 is recommended for hard use in all wave, freestyle & high wind applications:
- Wave
- Freestyle
- Crossover
- Freeride
Severne Apex Team SDM Mast
SV APEX TEAM - SDM
The highest performing, most reliable pro race mast. The Apex Team is our lightest SDM mast with a vigorous durability testing scheme behind it. The Apex Team has been through an intense development cycle and withstands the forces required by modern performance race sails. New technical features include carbon replacement where there previously were glass layers. A larger layer overlap and the addition of 90° carbon bring two significant upgrades; increased strength, and unaltered weight. The Apex Team maintains characteristics of all previous Apex masts; / ULTIMATE PERFORMANCE / INTEGRATED FERRULE / +7 MEASURED OFFSET ACCURACY / SLIPLOK PREVENTS BOOM FROM SLIDING
Our design objectives.
Achieve a higher durability mast while maintaining performance characteristics of Apex Pro masts.
What is changing?
Glass layers have been replaced with 90° carbon layers with bigger overlaps.

Simmer SX10 100% Carbon RD Mast
SX10 RDM
100% PRE-PREG CARBON // PRO WAVE
The SX10 masts present the best performance in the range with the fastest possible reflex response possible, giving the sails turbo-charged acceleration, an extremely wide wind range, and lightweight handling.
SX10 stands for 100% carbon content. They are designed from a top grade and high tensile strength pre-preg carbon. This technology ensures optimum control of resin content and resin distribution throughout the laminate. The carbon layup features and inner layers of 45 degree carbon weave to control torsion and quick reflex response. The outer layer carbon has a 90 degree orientation for highest possible strength.
The SX10 mast feature a progressive constant curve which means that the bend curve is constant but the base is stiffer than the top. This provides optimal sail dynamics allowing the bottom of the sail to generate power, and the top of the rig to quickly release power.
The mast is the spine of the rig, so to get the best possible performance out of your rig, choose SX10.

Simmer SX8 80% Carbon RD Mast
SX8 mast
80% PRE-PREG CARBON
The SX8 presents high carbon content for quick reflex respons that will lighten the feeling of any rig. Using the same high performance construction and bend curve as the SX10, the SX8 offers high-end performance with added durability therefore it is the best compromise between performance and durability.

The SX8 mast feature a progressive constant curve which means that the bend curve is constant but the base is stiffer than the top. This provides optimal sail dynamics allowing the bottom of the sail to generate power, and the top of the rig to quickly release power. The bend curve of the SDM and RDM’s are compatible with one another, but the RDM's are more durable, therefor more suitable for punishing wave conditions. SDM’s provide a faster reflex response, better stability and faster acceleration, therefor more suitable for flatwater sailing.
The Simmer wavesails are developed on the SX8 RDM and this is the mast that we recommend for this reason. The SX8 SDM is the recommended mast for VMax and 2XC and SC Slalom.
For perfectly tailored rig synergy and durability choose the SX8.
