Premium High Modulus pre-preg carbon mast engineered impossibly thin and impressively fast - over 15% thinner than standard carbon masts with increased bending and torsional stiffness.

The North Sonar HM Carbon Mast represents the pinnacle of foil mast technology. We've reduced the thickness of the submerged portion by over 15% compared to standard carbon masts while simultaneously increasing both bending and torsional stiffness. Available in three discipline-specific designs - HM80 for prone surf/pump/downwind, HM85 for all disciplines with wing foiling focus, and HM105 optimized for racing - each mast delivers more glide, more efficient pumping, and quicker turns with significantly reduced ventilation.

HM80 - Prone Surf / Pump / Downwind / Parawing :

• Shorter Chord Length - Over entire mast length for reduced drag
• Maximum Maneuverability - Quicker turns and responsive feel
• More Glide - Efficient underwater profile
• More Efficient Pumping - Less drag for easier pumping
• No Wind Power Required - Optimized for disciplines without wind assistance

HM85 - All Disciplines / Wing Foiling Focus:

• Slightly Longer Chord - In submerged part for upwind drive
• Increased Chord Near Top - Maximum stiffness with no drag penalty above waterline
• Wind-Powered Optimization - Efficient drive for edging against wind
• Versatile Performance - Covers all disciplines effectively
• High Top-End Speed - Easier to reach with efficient underwater shape

HM105 - Racing Optimized:

• 1mm Thinner - Further reduction vs HM80/HM85 for maximum speed
• Maximum Top-End Speed - Most efficient underwater body shape
• Tailored Chord Length - Good upwind drive with increased chord above waterline
• Not for Jumping - Optimized purely for racing performance
• Ultimate Speed - Less drag, higher easier-to-reach top speed

Revolutionary Construction:

• High Modulus Pre-Preg Carbon - Premium material for ultimate performance
• 15%+ Thinner Profile - Reduced drag vs standard carbon masts
• Increased Bending Stiffness - Better load transfer and response
• Increased Torsional Stiffness - Enhanced directional stability
• Ventilation Reduction - Significantly reduced trailing edge ventilation in all sea states
• Efficient Underwater Shape - Optimized for minimal drag

Performance Benefits:

Experience impossibly thin, impressively fast performance with the HM Carbon Mast. The over 15% reduction in thickness compared to standard carbon masts dramatically reduces drag while the High Modulus pre-preg carbon construction increases both bending and torsional stiffness for superior performance. We paid particular attention to ventilation reduction, so no matter the sea state, ventilation on the mast's trailing edge is significantly reduced. The more efficient underwater body shape means less drag and higher, easier-to-reach top-end speed across all disciplines.
