Bevaix boat

Twenty-two pairs of internal frames, also made of oak, were arranged head to tail to give almost vertical sides.

In every case, frames were always installed in pairs covering the whole length of the bottom, but alternatively supporting only one side of the hull.

The only exception is a sixth pair, which was a single piece of oak with a mortise cut in the center to function as a mast-step.

The Bevaix boat presents a very distinctive caulking technique, which clearly differentiated it from similar finds of this period from other parts of Europe.

Next, this string was covered by layer of mosses, which in turn was held by a wooden lath that was secured with thousands of little caulking nails, inserted into the seams from the outside.
