I have been on two trips to the Florida Keys where Jon Sairs, his wife Ann, and his mother Sally have sailed these modified sea kayaks. They look like great fun and seem to work very well. I only regret that I sold my sixteen foot open double kayak before I came to Florida. I hadn't used it in awhile and needed space in my new home for other stuff. That double would have converted to a great sailing kayak, one I could take my wife, grandkids or friends sailing in. Look for more information on these sailing conversions at www.sailyourkayak.com.
