I still have a Go-Joe on my board since that "mo-jo" post. And yes, advanced kiters can't help but make fun of it. Its been called "water wings, radar dome, air bag, board bitch and a beer cooler" so far.
I am an advanced sailor who is wary of the leash for anything but self rescuing. But I love kiting in these NW storms that kick up chest high chop here in the sound. Until the go-joe came my way I would sail conservatively in these conditions, now, after using this little board recovery device, I can push it as hard as I want. Kick'n off the board is no big deal, it takes zero time to spot the board (it really does flip over everytime) and because it is a sail on the board, its always coming back downwind to you at an angle. The Go-Joe makes it very easy and quick to re-connect with your ride. Its not that big, and doesn't seem to get in the way or cause any drag. When you are done you just pull the plug and deflate the bladder.
Look at this board I am using and you'll see why I got one of these.
Its darn hard to see because of the color, blue and black, and is like a knife in the water its so slender (less than 16" wide). This "moon goddess" mako surf kicks ass in the rough stuff. The 18mm of concave smooths it out and it never spins out.
I got my Go-Joe from Andy, at Bellingham Kiteboarding. I put it on the card and it was mailed directly to me from Ocean Rodeo. I think any of OR's dealers can do this for you if you are ready to ditch the leash and spend more time kiting, less time searching and never having to drag upwind again.
