Wow! Fascinating stuff Phillipe,Naval Architecture is a hobby-horse of mine, and I'd love to find out more. I often point out when asked the most significant invention of the 15th century "The Carrack or Caravel". This surprises people, but the invention of combination fore and aft rigged and square rigged vessels, multimasted vessels, the centeral rudder,and the (North Atlantic) seaworthy hull of Northern European vessels made the face of the future - our present day.
More than any other invention, the ability to dominate the sea, cross oceans, and project power through seapower made the face of our modern age European in outlook and philosophy - for better or worse.
Put that in your pipe and smoke it Gutenburg! (oh yeah, you couldn't have the pipe and tobacco to smoke if it wasn't for those little cockleshell ships that the Aztecs equated to floating mountains.) 
Sorry, the Yankee in me gets carried away sometimes. I just love sailing ships. Were I as rich as a Forbes, I'd have a carrack to tool around in.
What I wouldn't give to see the writeups and artifacts on those mudlocked ships! Not to mention whatever lines they can draw off them.
