Custom Quad 9 Pro Carbon
The new Goya Custom Quad 9 builds on the proven speed, ease of use, and wave-riding confidence of the Quad 8, while introducing a host of performance upgrades. Designed with a slightly more pulled-in nose and a progressive rocker curve, the Quad 9 delivers a tighter turning radius, while retaining the effortless glide riders loved in the previous generation, adding acceleration and top-end speed.
The new Pro Carbon construction is now lighter than earlier versions. The new shapes and construction feel slippier, looser, and more rail-to-rail-oriented, offering performance once reserved for custom boards only. A refined building process with lighter, higher-density foam in varying thicknesses throughout, and continuous Carbon/S-Glass layering contribute to our best and lightest Custom Quad ever, elevating wave performance to a new level of precision and flow.

Intuitive speed, power, and flow
Speed.
By refining the rocker, reshaping the bottom contour, and tapering the rails, the board’s efficiency, drive, and flow have been brought to the next level. Quick planning, fast acceleration, and a noticeably higher top-end performance, resulting in our quickest and most responsive rail-to-rail ride to date. Meaning you can make that section, make that lip, where before it would have seemed a far reach.
Shape.
A true World Cup wave board, the Custom Quad delivers quick planing and forward-driving carving turns, perfectly tuned to perform as a quad without compromise. Each model begins from the same master design to ensure a unified feel and aesthetic, then undergoes careful, size-specific refinements. Since rider needs don’t scale in strict proportion with volume, length, or rocker, each board is hand-tailored to a precise balance between proportional ride and feel—crafted to match intuitive performance in onshore to frontside World Cup conditions.
A more pulled-in nose improves fit and control in the most demanding, tightest sections, while the reduced width in the middle minimizes drag, increasing core center flotation, and speeds rail-to-rail transitions.

Bottom.
V blends into a single concave further forward, making it easier and quicker to respond for fast rail-to-rail transitions.
Rocker.
A new progressive-curve rocker creates accelerating yet easily controlled rail turns from nose to tail, resulting in the highest-elevating yet forgiving experience and ride.
Rails.
Thicker and fuller ahead of the mast track, to accelerate tail flow, the board feels surfy and forgiving up front, yet sharp and precise at the back.
Agility.
A sleeker, pulled-in nose paired with a progressive, accelerating rocker line and bottom V front to tail concaves, it unlocks turns once unimaginable—the added speed drives you confidently into the most radical sections and turns.
Construction.
The Pro Carbon construction continues to refine torsional flex with strength through our continuous lamination and a cohesive build between the mast track, deck, rails, and bottom, without patches or fillers. A new, higher-density, lighter foam shell wraps an entirely inner-core blank, as well as the area below the heel and footstraps, creating the ultimate strength-to-weight ratio. Finally, the finishing process has been revised to use even less paint than previous versions, infusing our favorite vibrant colors directly into the board’s build. A higher S‑Glass–to‑Carbon ratio delivers the optimal balance of performance, weight, and refined flex feel.
Pads & Straps.
Re-designed dual-density pads provide better grip, comfort, and durability. A new reduced layout and optimized dual-density blend mean you have the right support and cushioning where you need it, whilst saving weight and minimizing drag. The new square pattern is angled just right to give you maximum grip and connection to the board. A surf-inspired tail kick pad gives you that locked-in feel during air moves and turns.
Best-quality neoprene and fit MFC ® foot straps, with a size measurement guide. Set them as single-centered, offset, or double screw. Cover is compatible with or without shoes. Asymmetric washers let you custom-fit the strap width around your foot.
Finboxes & Fins.
Quatro ® US mast track and fin boxes, designed in-house and exclusive to Quatro/Goya, are lighter and stronger by design and bonding than conventional boxes. 4 x 5.5-inch US Boxes are 50% lighter—100g per box to minimize weight and seal the Carbon Monocoque™ construction.
MFC ® Quad Carbon fins are designed and constructed to match the Custom Quad 9, with a focus on ultimate speed and rail control. With a narrow core and added surface area at the tip, it provides enough support from the fin surface for earlier planning with high-speed rail-to-rail control. The Carbon Composites lay-up boosts Top Speed with progressive Torsion.
