The 90% Carbon Goya RDM is the performance oriented workhorse of their mast range-  designed strong to take insane beatings in heavy surf, yet light and responsive enough to give your sail the high performance feel that it deserves.  If you're sailing heavy water or abusive environments, but still want a mast that is light and lively, look no further-  the 90% RDM is your mast!



The main asset making the 90% Goya mast stronger than just about any other mast is Diagonal Flex™. It’s carefully tuned carbon content allows the 90% to bend to the amazing curves you know from laboratory photos, and Diagonal Flex™ enables the mast to twist extremely lively while in that shape, working in direct synergy with Goya sail design, be it while landing a back loop, catapulting at full speed, or floating through a closing out reef break.

The difference resulting from this feature is expressed by a very simple number: In the winter of its introduction, being the big wave season, between all Goya team riders, shops and distributors, we broke a total of three 90% Direct Drive™ masts. This was only possible through Goya’s Diagonal Flex™ technology.


The equation is very simple.

The wall thickness of a Direct Drive™ mast is about 50% stronger than that of comparable masts, while still being among the lightest weights, made possible by superb materials and aerospace industry build standards.



Goya masts have the smoothest build in the industry, resulting in extremely consistent mast bends across all sizes. Our mast layup gradually adapts to each sizing, enabaling us to keep the same bending percentages all the way from 12 IMCS on the 310 to 30 IMCS on the 490. These masts are capable of flexing effortlessly, offering outstanding durability and superior performance at the same time.

The US based factory building Goya masts operates at the highest level of composite manufacturing, with a client list including many aerospace and aeronautical companies. We take quality and consistency utmost serious.
