While it looks like C4 has drifted away from their early leading posiition in SUP development you have to admit they have maintained their committment to FUN.
It's inspired me to take the camping airbed down to the beach, pump up both it and my Cabrinha 12m kite at the same time, and then take the airbed for a kite..should be fun.
But seriously , I can see the applications, and at least, when you get a sore back from the kiting position on the C4, you can lie down on it in relative comfort.
Thanks for posting.
