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.
