Yes....you're the culprit! The yellow dinghy is the one that my wife and the 3rd grade teacher said was cute! Now I have to build one.

LOL excellent work.
I had some of these fence boards left over from Hurricane Ivan (been using them to board up windows the last couple of hurricane seasons, its easier to handle them on the ladder than plywood). I am hoping that the ones that are prone to warp have already done so, and the moisture content should be somewhat stable by now since they are only 1/2" thick. I oriented the pieces with the grain in different directions to minimize expansion/contraction issues.
I used the boards for the thwarts on my canoes. Thats what gave me the idea. I had intended to paint them, but after planing and sanding them smooth, they looked so nice I left them bright.
