The hull of the Roman wreck at Grado has been partially preserved under the cargo of amphoras. The right side presents a rare evidence of a section of the waterway. The ship has been assembled by mortise-and-tenon technique following a shell-first conception. All the frames, except one, are of pine while planking is either of pine and elm. Some strakes, of larix, are a repair made by patch-tenons; a wale shows an other kind of repair. Various signs left by the shipwright are on the hull. In the stern area, a box of wooden elements had to protect a ‘hydraulic system’.
