I’ve just completed the installation of the 19th plank on the starboard side. The 19th plank consists of a 3/8″ inner plank made of Alaskan Yellow Cedar overlapped with a 5/8″ Wana outer plank. The installation of the inner plank was posted earlier. The latest post (Alita Restoration Project/ Planking/ Outer Plank S19) describes the construction and installation of the outer plank.
