Wooden Ship Construction

Wooden ships have been constructed for thousands of years. Around the world, many different construction techniques have been used, some of them quite extraordinary. The ancient Greeks stitched the planks of their warships together edgewise to form an extremely light frameless load-bearing shell, much like a modern airplane fuselage. However, most wooden ships are built using a basic framing system that has changed little over the centuries.
