Forward topside planking was next thing on the list. All of the landings for the planks were checked for tolerance. Tolerance for gluing is 1/16". Thickened epoxy likes a little 'room' to develop maximum strength, so 1/16" is close enough. The forward sections get two layers of 6mm to equal the 12mm on the aft planks. I tried a piece of 12mm forward and while it would go around and make the twist, it seemed like we would be building a lot of stress into the boat. The 6mm went around really easy. Thanks to Charlie for the assist applying the first layer.
The second layer was applied with our trusty GelMagic, but this time from a bucket and mixed here in the shop. We were after a quantity to be troweled onto the surface. The early Spring warm snap had us hustling to get it all done before the epoxy went off.
The many drywall screws with plywood washers were pre-drilled on the outer sheet, then applied as clamps to hold the two thin panels together. Once the epoxy cured, the screws were taken out and it's an extremely strong panel. Many thanks to Russ, Charlie and Bill for the help on the second layer. It was nice to have extra hands!
While this was going on, I broke out the laser and marked the walls for the waterline. The DWL was marked, then another line, 3" higher for the bottom paint line. Once the boat is sheathed in fiberglass and primed, we'll use those marks to project the waterline for bottom painting.
