CHS Zero Base — Mast Base

The Zero Base is engineered for riders who want a mast-base system that is simple, secure and extremely compact. By positioning the U-Pin button discreetly on the mast, the design eliminates bulk and reduces the chance of accidental interference when rigging or sailing.

This minimalistic approach results in:

• smoother engagement and release

• a cleaner, streamlined interface

• reduced weight and mechanical complexity

• improved ergonomics, especially during rapid rig changes

Despite its reduced form, the Zero Base maintains the same durability and reliability expected from CHS hardware. It’s built to handle the demands of freeride, slalom and wave sailing while offering the convenience of a quick, intuitive mast-to-board connection.

Compatible with all CHS U-Pin extensions, the Zero Base is ideal for sailors who value efficiency, simplicity and performance without unnecessary components.
