Initially, we decided to replank the big gaps that were already there along each deadrise, and since this would involve five strakes each side I began by making up plenty of batten and dividing the space with them to define where the new planking seams would lie. This enabled me to ensure that all the new seams would have nice, fair curves. I also produced a simple router jig that would facilitate quick and reliable production of planking scarfs. There would be an awful lot of these joints to cut and this simple method ensured a quick and precise fit.
Then a cubic metre of Siberian Larch was delivered, and planking could begin.
