This is cool.
The rope caulk sown into the hull was interesting.
That is what makes construction stand out. The keel, the frames, and the planks are well known and are used today. Fixing the rope caulk with lacing rope between the planks is what makes this different from other examples. It looks to be that the frames are more widely spaced than I would expect, and perhaps this lacing technique could add some strength to the hull. I suspect that this wouldn't work for a larger boat.
