    This fascinates me, but I’ve got stupid questions:

    1. Is it just the friction between the tires and land that plays the role of keel or centerboard in this case?
    2. How close to the wind can you go?

      Not stupid questions.

      Yes, the tires act like a keel providing sideforce. The front wheel also acts like a rudder, controlled by foot pedals. The left/right is inverse of an airplane rudder.

      I don’t know the angle in degrees, but it felt like it could be very close to the wind. The wheels resist sideways from zero speed, unlike a keel that needs some flow moving to be effective. Also the carts have very little mass compared to a boat. Those things together make the acceleration really exciting.

      And sitting so low to the ground amps up the feeling of speed.

      I was sailing in the Mojave Desert when it was about 40-45°C. The lakebed dust gets into everything and never really washes out. So it’s a thrill to sail, but not as pleasant as being on the water.
