Chinook Mechanical Universal 2-Bolt US Windsurfing Mast Base

Chinook's 2-Bolt Mechanical Universal Joint is ideal for newcomers, wide boards, windsurf foilers, and couples who share gear. Why? Unlike mast bases that use rubber joints, when a mechanical joint bends, it isn't under tension. Without joint tension, a sail can be easily attached to (or separated from) a board in any position. And with Chinook's included Quick Release Plate, sail swaps are fast, simple, and safe.

Chinook's two-bolt mast bases are two separate pieces, and include Chinook's Quick Release Base Plate. This system makes it easy to pop off your mast base while leaving the low-profile plate assembly attached to your board. The plate means no more hand tightening your mast base before every session, and loosening it after. Ideal for couples who share gear, and enabling quick board/sail swaps, the Chinook Mechanical Universal 2-Bolt US windsurfing base means more time on the water!
