Pretty cool, but I am not sure how unusual this type of construction was or how different it was from, say Roman or Greek ships of the time. I am no engineer, but I do know that the nature of wood is you have to cut it into into strips of various lengths, widths and thicknesses to build with it. To make those strips into a boat, you have to fasten the strips together, arranged into a symmetrical hull with a center beam.
So is it the papyrus layers that is unique, water repellent?
You have to read the article to get the importance of the description Herodotus gave in his book, which had been doubted for years, and the fact that the ship they discovered has exactly those unique construction features he described.
