The CLAssic

The mast that started it all, the Project Cedrus “Classic” is still exceeding industry benchmarks for stiffness and strength, while remaining one of the lightest and only truly universal foil masts on the market. Whether you want a stiffer mast for your favorite kitefoil, or just want to try as many wings as possible as you learn to prone foil, The Classic will grow with you. Pair it with the lightweight plate, and you’ll have the lightest setup at the beach. Go with the Strong Mount if you’re a wing-foiler, and don’t ever worry about bending your aluminum mast or breaking your carbon mast again. The Classic is available in lengths as short as 55cm up to 90cm for the perfect prone, wing, and kite configuration.

The clydesdale

The Clydesdale was developed primarily to offer increased lengths without signficant changes to existing tooling and design. With an additional ply of unique spread-tow fabric, a 3rd stainless steel mount screw, and a deeper, tighter fitting collar against an aluminum plug extending from the mast, The Clydesdale is stiffer and stronger than the Classic with only a ~300g weight penalty. Targeting the most aggressive wing, windsurf, and SUP foilers on big boards and tall masts, The Clydesdale is available in 93cm and 96cm (100cm+ assembled) lengths. Shorter configurations for heavier riders or those less weight sensitive can be assembled upon request. However, without a single structural failure of a Classic mast since inception, shorter Clydesdales are justified for unique reasons.

Length

The patented architecture of Project Cedrus permits customization in 2.5cm/1inch increments. Whether you’re sizing for a specific water depth, wave break, or between sizes of OEM masts, the mast is made for you. When specifying desired mast length, please note that “Cedrus Length” refers to the structural core, and that adapters and mounts add about 4cm to the total length of the mast assembly. All brands measure their masts differently, so please measure your existing setup from the underside of the board to the end of the mast (and plug where applicable). Adapter designs and mount heights vary slightly, so if you need exact lengths with your desired adapters I can provide them following deposit payment.

Weight

Total Project Cedrus weight is model, length, and mount dependent. Using the equations at left, you can estimate the weight of your desired mast by multiplying the Cedrus Length value by 12 (for Clydesdale) or 9 (for Classic) and adding 223g or 380g, respectively. Then and add mount weights + 150g for a typical adapter to obtain total assembly weight.

section profile

Both mast profiles feature a constant 19mm thick, 120mm chord length hydrodynamic profile. The mast does not taper near the fuselage as this significantly reduces torsional stiffness and can promote ventilation. For reference, and unintentionally, this is a similar profile to the Axis aluminum mast. Most OEM carbon masts are a bit thinner, a result of solid or cored architecture which increases weight and cost. Optimized for stiffness, strength, weight, and compatibility, the slightly thicker section of Project Cedrus is neccasary to achieve the hollow architecture allowing for all mentioned benefits. The ideal speed range of the mast is highly wing and rider dependent. Most riders do not notice any increased drag, and some actually find themselves more comfortable at speed due to better control with a stiffer mast. Low-end performance is outstanding, as thin masts can actually have higher lift-induced drag which is evident at the low end.
