Simmer G7 Quantex Windsurfing Board
£2,399.00
// PERFORMACE ALL WAVE DESIGN
The Quantex is a high performance wave board that specifically excels in wind swell wave venues. As the name indicates, the Quantex genealogy includes both the Quantum – the original Simmer Style wind swell wave board, and the Cortex – the innovative short rail line Simmer wave board, specifically designed for performance riding in less than ideal conditions. The rocker of the Quantex comes from the original Cortex. Just as the rocker of the Simmer Flywave, it was developed from Kai Katchadourian’s special Peahi board. This means a relatively low rocker in the center of the board combined with a constant curve rocker in the rear part. The main features of this rocker is a high wave riding-speed range. The rocker provides a stable platform in high speed conditions with bigger and choppier waves as well as providing the rider with speed containment in slower onshore conditions.
The central challenge for wind swell performance wave boards is to, provide tight turning board in smaller waves and control bigger waves, which in wind swell locations means chop and high wind. In the Quantex, the mechanism for solving this problem lies in the outline. By fitting a relatively low curvature central outline into a relatively short package, we have achieved to combine stability at high speeds speed with agility at lower speeds. A slighly wider tail that is finished in a jet tail, that is a swallow with the corners chamfered off, provides an excellent platform for early planing and for carrying speed through the bottom turn when winds and waves proves less drive.
The Quantex 109 features a slightly different rocker and outline that combines a slightly longer rail length with single concave to vee-based rocker optimized for carrying heavier sailors and bigger sails.

Compact Outline Tail Design
The chamfered tail design allows the board to draw snappier turns when you engage it in rail-to-rail maneuvers. The Quantex features a longer and wider tail needed to navigate flatter sections of the wave with maintained speed and maneuverability.
Contours
An efficient rocker with a progressive Vee with a low-drag midsection for quick planing, as well as speed in less powerful surf. The double concave accelerate towards the tail causing the water flow to follow, absorbing chops and creating drive towards the fins for snappy turns in all conditions.


Parallel outline
The parallel outline converges into the tail area underfoot providing ample lift for early planing and lots of pop for aerials and jumps. The Quantex can easily adapt to different turning angles. With the stance set as far back as possible, the inner angled rear section adds grip in top turns, and extra torque in tight bottom turns.
Double Screw Inserts
Double footstrap inserts for maximum load and adjustable stance settings for tighter or personal preferences to either 14.5 cm or 15.5 cm for the front straps or 14 cm or 15 cm width for the back foot strap.
Dual-Density EVA Foot Pads
Dual-density EVA pads, 4 MM high density top layer with diamond grip + heat pressed dots for superhero traction. The new pads feature a 8 MM soft core heal bumper for maximum riding comfort + tail kick.


SELF REGULATING GORETEX © AIRVENT
The Quantex comes standard with a self-regulating Goretex © Air vent which allows air to pass back and forth between the foam core and the exterior of the board, whilst being completely waterproof. The double-layer membrane of Goretex on either side of a rubber O-ring prevents pressure build-up inside the board, minimizing the risk of delamination caused by overpressure inside the board even during a flight. You’ll never need to unscrew an air vent screw again.
Standard fin setup // TRI
The tri fin setup will provide early planing, great upwind tracking and ease of sailing while still providing an insanely tight turning radius. On the wave, this setup will give you the best possible projection and drive in turns, assisting the sailor in maintaining speed through the bottom turn, even in less powerful waves. Versatility and snappiness with a user-friendly feeling are the main characteristics of this setup.


Alternative fin setup // QUAD
Equipped with a quad fin setup, the Quantex gets more planted and controlled at higher wave riding speeds. The power of the fin cluster acts further forward, which drives the front rail into the water and gives the board added control in turns. At the same time, the shorter depth of the two rear fins makes it easier to dig in the rail at high speeds which means that the board feels more responsive in fast side-shore or cross offshore conditions
New! Carbon Airex Fins
The construction features a carbon/fiberglass exterior, molded with a laminated infusion process onto a Airex foam core structure. This makes the fin extremely lightweight while maintaining strength and stiffness. The Simmer Style composite fins are one of the lightest wave fins on the market; they weigh half the weight compared to traditional G10 fins.
New! Pro Edition Foot Straps
All-new foot strap for the ultimate combination of riding comfort and durability. Features a 7 mm neoprene padding and a large velcro patch for easy adjustment. Screw holes for both single and double screw inserts.
Superior Fittings
Screws for the footstraps and finboxes are made of the highest-grade stainless steel. Both footstraps and Slotbox fins are adjustable with the same tool, the T20 Torx tool included with your board. Super easy, super reliable!

Simmer G7 Omnia Windsurfing Board
In stock
// WAVE-FOCUSED FREEWAVE
The new Omnia is a completely new shape from the ground up. It is a classic freewave board that combines fast and crisp freeride performance with remarkable abilities also for wave sailing. The board is based on work done with our pro team starting in 2021. Our team requested a board that was extremely fast, but at the same time very controlled for radical jumping conditions in Pozo. The board needed grip and speed for tight turns in wind swell environments. For this, we went to the drawing board and developed a new rocker with added curvature from the front-strap-area to the front of the mast track, but with a super fast tail. This we combined with a new vee-profile that is flatter in the center with the vee accelerating both towards the nose and tail. Particularly in the front part of the board, this vee is combined with a double concave. The flat tail rocker gives the board its high-speed stability, with the low center vee providing good pop and agility, while the double concave in the front part of the board acts as a cushion, making the board a real chop absorber.
When thinking about ideas for the new Simmer Freewave board, we had our team riders raving about the combination of speed and control of this bottom profile on our minds and decided to base our new freewave development on it. After some iterations, we ended up with a swallow tail outline with a relatively wide and stable nose and a curvature distribution that keeps the tail relatively straight for added grip. Interestingly, now the development went in the other direction, and the outline from the production prototypes was brought over to the to the 75-liter pro model version that is now a part of the production lineup, sporting five slot boxes. The rest of the lineup uses the exact same bottom shape and progressively slightly fuller rails on the bigger models. Except for the 75, all sizes have a center powerbox and slot box thruster boxes. The Omnia replaces the Helix. It provides a faster and more agile ride with added performance in waves, while at the same time feeling more fun and exciting in a straight line. The name Omnia stands for “seize everything,” which explains the board characteristics to the point.2026 Simmer Blacktip Legacy

- Premium low-stretch materials – Quick reactivity and minimal profile distortion
- Effortless performance – Smooth power delivery, light, balanced
- Reinforced detailing for greater durability – longer lasting high performance
The 26/27 Blacktip Pro links its performance directly to the Team Carbon and has been re-engineered to deliver lightweight power and razor-sharp responsiveness across all wave sailing conditions. Marc Paré’s development objective was clear: create top-end performance with maximum ease of use, combining lightweight handling with a highly durable construction.
The luff curve has been re-designed to make the sail more forgiving and easier to handle, delivering a smoother in-hand feel. To further enhance responsiveness, we developed a new laminated scrim—VX-Ply—that combines vertically aligned fibers with an X-Grid for maximum durability. VX-Ply stretches significantly less, ensuring optimal load distribution across the entire sail body.
The Blacktip Pro is built for durability, with load controling VX patches and reinforcement that achieve superior load control and longer-lasting performance. By removing the upper stretch control, the sail now delivers more precise twist under load, extending its wind range even further.
The 26/27 Blacktip Pro is a maneuver-focused wave sail designed for effortless PRO-level performance in all conditions. With enhanced durability, lightweight handling, and Simmer’s legendary build quality, it will take your wavesailing to the next level.
