Attached is a photo from Pygmy's website of their Queen Charlotte which uses a flat deck but creates leg and foot room by cutting a v-shaped notch in the deck and stitching it together. But given the thousands of people who have built cambered-decked boats, I wouldn't shy away from attempting another one. Maybe we can help you figure out what happend with your first one. Maybe you did a saturation coat on the underside of the deck and didn't rough it up with sandpaper before attaching it to the shear clamps, so the epoxy didn't get a good bite? Did you try for a cleaner look by not nailing the deck on and relied on straps and tape to hold until the epoxy cured? Maybe just a simple mis-mixing of epoxy? Just making some guesses... Dean
