Having about 14' of shear plank, sponson and guard replaced. Plank and sponson were originally Shaw Island old growth fir (1943), and guard was ironbark. Oak frames still okay. Replacing planks and guard with yellow cedar and purple heart. It hurts to see it and write the check, but then it is nice to realize that a wooden boat is all replaceable parts.
Note that there is no covering board on the shear plank. It makes it easier to replace the plank, but it leaves the top edge open to the scuppers which caused the problem. The starboard side was done a few years ago, same problem.
