I just finished the exterior fiberglass on my Northeaster and had some problems getting the 6oz cloth to lie flat on the garboards. The wrinkles just would not come out, and rolling them flat seemed like a 16-foot long 3-D version of Whack-a-mole.
In the end, the wrinkles were still there and when I sanded them flat, it cut through the cloth. I ended up recoating the bottom with a twill fabric, and what a difference - it draped perfectly and wet out with no bubbles or wrinkles. Given the user friendly nature of the twill fabric, is there is any advantage to the plain weave that CLC supplies with the kit?
By the way, hat's off to the overall design of the kit! The boat went together quickly and without a hitch. I've built a Mill Creek 16.5, and the dory has been a far easier project.
