The X-Base UXT is the ultimate evolution in mast bases — engineered to eliminate the hassle of removing the baseplate after every session. It uses a dual T-nut screw connection to deliver a rock-solid, slip-free mount and smooth, precise adjustment.

When it’s time to stow your board or clean the base, the tendon & pin unit can be detached in seconds, making transport and maintenance effortless. Its ultra-low profile design minimizes the gap between sail and board (“Close the Gap”) and reduces bulk in your board bag.

The UXT version includes a built-in T30 tool in the pin head — ideal for tightening the baseplate or any other T30 screw (footstraps, fins, plugs), so you never get caught without a screwdriver again. The tendon joint is crafted from a high-tech material about 50% tougher than conventional compounds, with a safety rope made from ultra-strong UHMWPE.

All edges are fully rounded to eliminate sharp areas, protecting your hands, feet, and the board deck. X-Base UXT is Neil Pryde’s most refined and reliable mast base ever made: perfect for riders demanding pro-level performance, ease of use, and long-term durability.
