Back about 4 or 5 years ago, I decided to figure out how to plank a guideboat rather than strip it. I used flat sawn white cedar, which I had on hand. Big mistake. I managed to plank it using the Grant lap, varnished it, and traded it for a new custom-built fiddle. The boat is now back in the shop with some serious problems. The flat sawn white cedar cracked like crazy. Last year, we filled all of the visible cracks with thickened epoxy, but more cracks opened up over the winter. Some of the filled cracks even opened up further. The plan is to sand the varnish off the outside, fill the cracks with Durham’s Rock Hard Water Putty (or epoxy?), sand it smooth, lay on 4 oz. fiberglass/epoxy, and finally paint it. All of the brass, gunwales, and decks were easily removed, and the sanding is just over half done. I invite the forum to make suggestions, and I will post progress. Lesson learned – white cedar is fine on a stripped boat, but don’t even think about planking with it.
