Code Ultra HM Plus Mast

The Code Ultra HM Plus Mast is the top-tier mast offering from Code Foils, built entirely from ultra-high modulus carbon fiber. Available in 75 cm, 80 cm, and 85 cm lengths, it shares the same mold and hydrodynamic profile as the brand's original High Modulus mast but uses a higher-grade carbon layup to deliver substantially greater rigidity. Code Foils positions this mast as an addition to the lineup rather than a replacement for the standard HM version, giving riders a choice between a lighter option and a stiffer one.

The mast features an extended blend down to the base plate and a tapered, thinned lower section designed to reduce drag when the rider is high on the mast. According to Code Foils, testing of the 80 cm variant showed a 41% increase in torsional stiffness and a 59% increase in flexural stiffness compared to the original High Modulus mast.

• Material: Full ultra-high modulus carbon fiber
• Available lengths: 75 cm (29.5"), 80 cm (31.5"), 85 cm (33.5")
• Torsional stiffness gain: +41% over standard HM mast (80 cm test)
• Flexural stiffness gain: +59% over standard HM mast (80 cm test)
• Includes: Mast cover and mounting hardware

Code Foils designed the Ultra HM Plus Mast for riders who prioritize control and responsiveness over minimizing weight. The additional stiffness is most noticeable for heavier riders, those flying larger wingspans, and anyone pushing speed in downwind runs or powered-up conditions. Riders under roughly 175 lb on moderate-span wings are less likely to feel a meaningful difference compared to the standard HM mast and may prefer its slightly lighter weight.

Each length targets a different use case. The 75 cm suits shallow-water spots, prone foiling, and dock starts. The 80 cm is the versatile all-rounder across wing, surf, kite, and wake foiling. The 85 cm adds clearance for wing foiling, bigger swells, and tow-in sessions. All three lengths are compatible with existing Code Foils setups without adapters.

Within the Code Foils catalog, the Ultra HM Plus sits above the standard High Modulus mast, which remains available at a lower price point for riders who favor light weight and still want above-average stiffness. Both masts share identical profiles and base-plate geometry, so switching between them requires no additional hardware. The Plus effectively serves as the flagship mast option for the Code system.

Among competing brands, the Axis Ultra High Modulus mast occupies a similar performance tier but carries a significantly higher retail price — often above $2,000 — making the Code Ultra HM Plus a more accessible entry into the ultra-stiff mast category. For riders already in the Code ecosystem looking to upgrade feel and stability without changing their wing or fuselage, the Plus mast is the most direct path.
