Type of planking

Post by trebot » Sat Sep 22, 2018 6:30 pm

Have a 1956 Continental, 18'. Need to replace section of bottom plank at the stern. What type of wood was used in construction on the bottom?

Outer planks would have been Phillipine mahogany. Sometimes it is hard to find. I don't see why the easier to find African would not work on a bottom repair that is going to be painted.

The closest species I could find to the original (which was old growth) is plantation grown Dark Red Meranti. I despaired using it because the quality is highly variable and sometimes will just crush under the pull of a fastener. As I understand things, the Philippines put a moratorium on harvesting several years ago because supplies were so depleted. That may account for the disappointing quality I have seen. I do have a couple of decent boards that I am hoarding, but not enough to do the entire bottom of our 1937 35' cruiser. I would agree that African is a good substitute for the original. But the original is not gettable anymore. I used 15mm 1088 marine plywood to do the bottom and it seems to have worked out fine. Scarfing is easy and will yield whatever length you desire. I considered African but I would have planed away 50% of the material and spent months doing it. For what it is worth, that is my experience.
