    GTR + Aluminium

    The freerace foil. Designed for speed on a reach, broad downwind and with power reserves to drive back upwind. Ideal for fast, sporty recreational foiling, fast foil jibes and setting your personal best top speeds

    WHY "PLUS"?

    Compared to the original GTR, the new GTR Plus swaps the 95 Standard fuselage for the new 95 Plus fuselage.

    This new fuselage shifts the front wing forwards and reduces tail wing angle to make it more aligned with the front wing, creating what we call a High Efficiency Foil Geometry (NZ Pat. App. No. 751177). With both wings flying through the water at more parallel angles, you release more speed, you get quicker acceleration and more control.

    A cross between the GT and the Race.

    Recommended for those looking for a less powerful version of the Race or a more powerful version of the GT.

    Choose this foil if you want a racing allrounder. It's fast, it goes upwind well but it's not too powerful.

    Mast: ALuminium 85cm | Fuselage: Aluminium 95cm | Front Wing: Carbon 800cm2 | Tail Wing: Carbon 330cm2


    Can I use a normal windsurf board with Starboard's foil?

    We can't recommend normal windsurf boards because the board's fin box will eventually break. We did use regular boards ourselves during development and we know many people will end up using regular boards for foiling; and they work because our foil geometries require boards to have their fin boxes placed in standard windsurfing positions. We can only advise you do this at your own risk. If you do choose to use a regular board, the wider the board, the better.

    Carbon foils see an upgrade to the masts from the alloys. Still on a fully modular platform and with the ability to change between wings. These are already PWA winning race foils and are used by many Starboard and non Starboard team riders alike.

    Forget weight, forget flex: foil masts have to be stiff and torsionally rigid to achieve controlled flight. The stiffer, the more stable. And the more stable, the more control and more performance the foil delivers. Starboard masts are built in 100% pre-preg carbon, with forty layers of wrapped high-modulus uni-axial, bi-axial and tri-axial Toray carbon hydraulically pressed, heated and fused into one monolithic mast of incredible stiffness.

    The shape of our mast has also been optimized for flexural and torsional stiffness. Computer-simulated analysis shows the Starboard mast, by virtue of its shape alone, is already up to 52% stiffer than a traditional mast.
    Wing Technology

    We found G10 wings and glass fibre wings to flex too much, no matter what we tried. Flex reduces control and stability. Since thicker wings would reduce performance, we chose to make all Starboard Wings in 100% pre-preg Toray carbon. Like for the mast, stiffer wings equal controlled and stable flight.

    Fuselage Technology

    Aluminium. Why aluminium? A-B testing repeatedly found aluminium fuselages to outperform carbon fuselages in spite of their weight and the extra care needed to avoid corrosion. The longer the fuselage, the more apparent it became: unlike masts or wings that are thin, because of the solid, circular cross-section of a fuselage, not only is an aluminium fuselage stiffer, it is also tougher, stronger and torsionally more rigid. Since added weight is not a disadvantage in foils, possibly even an advantage, we chose 6061 aluminium for the fuselage construction.

    Wing Saddles

    The key to a good saddle design is width and square, mechanically locking shapes. With a flat and large mating surface that makes the most of the fuselage's width, Starboard's wings bolt-on with ease and allow wings of all shapes and sizes to be fitted. Want to attach your own wings? We supply G10 shimming blocks that allow you to bolt on any wings to the Starboard Modular Foil Platform. Fuselage Fitting

    A super stiff mast, a hyper-rigid fuselage and full carbon wings would all go to waste if the fuselage fitting wasn't up to par. So we designed our own patent-pending fuselage fitting that not only allows for convenient disassembly, it also allows four lateral bolts to crank up the fitting pressure between the mast and the fuselage to the max, enhancing torsional rigidity and creating a single, fused high performance unit. Three Torx bolts on the bottom carry the vertical loads. When the fuselage fitting could be the weakest link in a foil construction, our patent-pending system turns the design equation upside down, making the connection a stronger and stiffer link than had we made a single-piece mast fuselage combination.
