Wando (ca. 1080)
This vessel had very strange forms of construction. Thick planks were edge-joined by enormous mortise-and-tenon joints, some of them long enough to pass through three strakes. The turn of the bilge on each side was accomplished by a plank shaped at right angles. Little information has been published about this wreck.1
