Naish Foil Mast HM Carbon | High-Modulus Carbon Mast

The Naish Foil Mast HM Carbon is the top-of-the-range mast in the 2026 Naish Alpha system — built with strategically placed high-modulus carbon laminate over a dual expansion foam core to deliver more stiffness at the same weight as standard carbon. Available in 75 cm, 80 cm and 85 cm, it suits wing foiling, kite foiling, surf foiling and downwind at the highest performance level.

It's the choice when only the stiffest, most precise mast in the Naish range will do — for riders who feel the difference and want direct, lag-free feedback at speed.

Who It's For

Advanced and performance-focused riders — those who push the top end of their riding, whether that's high-speed kite foiling, racing, technical wing foiling or serious downwind work. If you've been riding carbon and you're feeling mast flex at the limit, or you want the absolute best Naish can offer in 2026, this is the mast. It's not the entry point into carbon — it's the ceiling of the lineup.

Key Features

• High-modulus carbon laminate + dual expansion foam core — more stiffness at the same weight as standard carbon, with a lighter, stiffer result than previous Naish masts
• Variable chord technology — combines high torsional stiffness with reduced wetted surface area at speed, lowering drag without sacrificing rigidity
• 115 mm chord, 15.5 mm thickness — short chord reduces drag when riding high on the mast; measured dimensions for real aero and hydrodynamic benefit
• Anti-ventilation foil section — specifically engineered to prevent ventilation at high speeds, allowing more top-end performance without spinning out
• Instantaneous rider input transmission — ultra-stiff construction means no lag between body movement and foil response
• Optimal torsion and bending stiffness balance — tuned for control and precision, not just raw stiffness
• 75 cm, 80 cm and 85 cm options — the 80 cm adds an extra choice between the standard lengths, useful for riders who find 75 cm marginal in swell

Real-World Feel

If you've ridden both the standard Carbon and the HM, the difference is clearest at the extremes — hard pumping loads, top-end speed, and aggressive turns where a less stiff mast would introduce a small delay or flex. The HM has none of that. Feedback is immediate, the foil goes exactly where you tell it, and the anti-ventilation section means you can push harder through turns without the mast letting go. The short chord is genuinely noticeable at high mast positions — it reduces the drag you'd normally feel when riding the mast high in lighter winds. For most recreational riders the standard Carbon will do everything they need. For those who'll actually feel the difference, the HM earns its price.

Setup and Fit

Uses the same 2026 Alpha system monolithic top connection as the standard Carbon Mast — fits directly with the Alpha Alu Fuselage and all current Naish front and rear wings. The 75 cm is a strong choice for kite foiling and onshore use. The 80 cm bridges the gap between 75 and 85 — useful if you ride in varying swell and want a versatile single mast. The 85 cm is for open water, bigger swell or downwind, where hull clearance matters.

Materials and Construction

High-modulus carbon laminate, strategically placed for optimised torsion and bending stiffness. Dual expansion foam core for lightweight construction. 115 mm chord, 15.5 mm thickness. Anti-ventilation foil section profile. Compatible with the 2026 Alpha system.

Size Guide

The 80 cm is a useful option if you want one mast that covers a broader range of conditions without committing to either end. For most kite foilers, 75 cm is the standard. Wing foilers in the UK often go 75 cm or 80 cm.

Pairs Well With

Matches directly with the Naish Alpha Alu Fuselage and the full range of current Naish wings — the complete performance-end of the 2026 Alpha system.

Why We Stock It

The HM Carbon is the mast you buy when you know why you need it. It's a serious piece of kit at a serious price, and for the right rider it's genuinely the best foil mast Naish has ever made. We stock it because some of our customers will feel the difference — and for them there's no point compromising. If you're not sure whether the HM is right for you, come and talk to us.

FAQs

What makes the Naish Foil Mast HM Carbon different from the standard Carbon Mast?

The HM uses high-modulus carbon, which delivers more stiffness at the same weight as standard carbon. It also has a shorter 115 mm chord, an anti-ventilation foil section and variable chord technology — all aimed at performance riders who want the absolute maximum from the 2026 Naish system.

Is the Naish Foil Mast HM Carbon worth the extra cost over the standard Carbon?

For advanced riders who push hard at speed and can feel mast flex, yes. For intermediate riders or those riding recreationally, the standard Carbon mast will likely feel identical in everyday use and saves a significant amount. Be honest about your level before committing.

What does the anti-ventilation foil section do?

The specially shaped foil section on the HM Carbon resists ventilation — air being pulled down the mast at high speed — which can cause sudden loss of lift and spinning out. The anti-ventilation section lets you ride faster and harder without this happening.

Which size Naish Foil Mast HM Carbon should I choose?

75 cm is the standard for kite foiling and most wing foiling. The 80 cm is a good choice if you ride across a range of conditions from flat water to light swell. The 85 cm is for open-water riders, downwind and any scenario where maximum hull clearance is needed.

Is the Naish HM Carbon Mast compatible with the 2026 Alpha fuselage?

Yes — it uses the same monolithic top connection as the standard 2026 Carbon Mast and fits directly with the Alpha Alu Fuselage. All current Naish front and rear wings are compatible.

What does variable chord technology mean on the Naish HM Mast?

The chord (width of the mast cross-section) varies along the mast length. This combines high torsional stiffness in the areas that need it while reducing drag by decreasing the wetted surface area where the mast rides close to the water surface at high speed.
