Spectrum Mastbase
Lightweight, 90mm mast track compatible and has a hydrodynamic profile that delivers an unmatched connection to your board. The deep mast socket provides a tight, secure connection with your foil. The low profile and slick form minimize resistance during touchdowns. We kept the base as lightweight as possible while adding strategic internal struts to absorb stress from the mast stringers. We also opened the screw attachment points for quicker assembly.
Delivery: The Mastbase comes with 4 M8x30mm Torx screws and 4 T-nuts.
