This kit allows Hobie boat owners to use the WindPaddle sail while also using the MirageDrive propulsion unit. It mounts in Hobie’s sail mast receiver using a RAM expanding mount. It allows you to shuttle your sail from its coiled and stowed location under your legs to in front of the MirageDrive pedal unit. Uses the Hobie mast mount receiver molded into your boat as a front anchor point for locating the WindPaddle sail. Use your WindPaddle sail in conjunction with Hobie's MirageDrive system for foot-action paddling.
