Landsailer Mk I
Boat on wheels or Go-kart with a sail? You decide. Either way, the concept is the same. It is a craft with both wheels and a sail. The sail is controlled by a rope like on a boat, while steering is done by turning a steering bar with the feet.
The beam system I used to connect the front wheel proved to be strong at all forces except one - twisting. And twist it did. It was not uncommon for the mast and front wheel to be leaning in excess of 30º.
Maximum speed was clocked at 24.5 mph with a GPS, although average speed was closer to 15.
"Patriotic" red, white, and blue color scheme was entirely on accident. I chose to paint the craft blue before I even knew the colors of the Sunfish sail I was to use.
