Hi all. I picked up my CH18 kit around the end of August and have it wired up and ready for bulkheads. The forward bulkhead fit real nicely. The aft bulkhead seems too short from the inside chine to the bottom of the shear clamp. I have about a 1/4 inch gap along the bottom between the bulkhead and the bottom panels. Per the plan, the shear clamps are glued 1/4 proud of the top of the side panel so not sure where I went wrong. The bulkhead is too wide, also, at the shear clamp(but ok near the chine). When positioned per the manual, it spreads the beam to around 25 inches from the 24 1/2 inches specified in the manual. There was really no location in the boat where the bulkhead would fit properly, so I drew a cut line on the bulkhead from the inside chine to the top of the bulkhead under the shear clamp (about 3/16 inch in from the side panels) on both sides. That slanted cut brought the beam back to ~ 24 1/2 inch, but still have the gap at the bottom of the bulkhead. I'm just adding spacers to prevent warping the bottom panels when I wire in the bulkhead. Anyone else have this problem? Otherwise, the rest of the hull fit perfectly. Every thing is straight and true. The bow and stern are plump and the side panels and bottom panels aligned spot on. Just wondering what went wrong with the aft bulkhead.
