The ideal mast height for prone foil surfing, learning to hang glide or foiling in shallow waters. Precision CNC machined from 6061-T6 anodized aerospace aluminum for minimal drag, with structurally engineered joints for exceptional strength to weight ratio.
Strong and Light The cross-sectional profile of the aluminum mast features an optimized strength-to-weight ratio.
GeoLock Designed for durability, our unique GeoLock tapered geometry locking system provides a more effective load bearing connection between the mast and hull by locking them together so they feel like one piece. Screws engage the GeoLock while load transfer now occurs across the entire cross-section of the mast profile, allowing for more efficient load transfer and a longer lasting connection.
Board Adapter (sold separately) The Sonar Foil System is connected to the board by a lightweight, CNC-machined aluminum board adapter with tapered geometry that engages the mast. The board adapter and mast are fused together to create a bond for optimal load transfer and a stronger, more direct feel and steering impulse during foiling. Board adapter and foil to board mounting hardware not included.
