Way back I saw an instructable of a guy who mounted a windsurfer sail onto a skateboard and rode it down the beach. At the time I didn't have the ability to purchase either a windsurfer or a mountain-board, so the project dissapeared to the back of my mind. The other day it re-emerged as I got given an old windsurfer. So after half-a-dozen runs to the hardware store, a land-sailing-skateboard was made
I already have a V2 with front steering in the works...
And yes, those may be 3D printed heim joints. Probably not a good idea, but I'll see how they go.
