Well, not yet, but I'd sure like to see it.  especially considering how easy it looks from the dugout canoe seen here: http://www.northvancanoeclub.com/  Click on "outriggers pictures" & scroll to about mid page 

Four panels for the main hull, hard chines, a little bit of rocker, a bit more beam, and maybe a battery op bilge pump for capsize recovery.  Then zoom zoom.  

Do I keep dreaming?   if CLC doesn't do it, we'll do it here in Western Wakinikona (that's Hawai'ian for Washington)
