Maybe some of you have seen a large parafoil kite being used by adventurous individuals. You may have noticed the kite cart where the person is sitting. This shows the simple construction of a sail kart using a racing seat.

A steering bar and control arm are installed to provide unusual experience. It can stop easily by coasting and can turn 90 degrees to the wind. It is protected from rusting by painting any exposed metal. The type of seat used will not provide more weight since they are light. Other formed plastic go kart seat can also be used. I like the type of kite that has great power capability.
