Just looking at the pictures it seems the Uluburun ship was made with long planks the length of the ship whereas the ship in the OP is made with 2 cubit (approx 1.5ft) planks mortice and tennoned together. The ships are also just different. The one in OP was about 25m long, flatter, made for the Nile and, it seems, of a kind described by Herodotus. The Uluburun ship was about 10m long, less flat, made for the Mediterranean, likely not made in Egypt, and several hundred years older.
