Hi Tom,
Flew this weekend at a NH Float Fly and the winds were blowing 15-20 mph. Not a lot of fun for most but I managed to get in some flights with my electrics that I don't care about much. I did fly the Kingfisher once and many thought I was crazy but that thing at 10 1/2 lbs handles the wind with no problem. There were 8" or so waves with white caps and it looked like some of the old Navy pictures of the real ones crashing through the ocean. Landings and takeoffs were without issue. The Kingfisher design is really so good in the water it surprises me and everyone else. While other planes were having all kinds of issues especially after landing (flipping over in the wind) the Kingfisher stayed planted on the water. It took a little to get it turned around but once that was accomplished it was easy to taxi back. The pictures were taken on Sunday where the wind calmed to about 12-15mph until about 10:30 when it went up again.
