The Core Spectrum Mastbase is a lightweight, 90mm mast track compatible base 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. Core kept the base as lightweight as possible while adding strategic internal struts to absorb stress from the mast stringers. They also opened the screw attachment points for quicker assembly.
