One of my kitesurfing buddies sent me a link to this article on a new type of kite that has been designed for Stand Up Paddleboards. Its a very large kite; 17m, and is a 2 line design. Apparently its meant for low winds in the 5-15 mph range.
Theres an article about it in the latest online kite magazine
