I decided to take the day and update most of my documentation, so here’s the current Japanese traditional boat project I’m working on. I have another project with some slow research and decision making, but this is one that I basically have all the information on, since it is based on a pretty complete set of drawings.
This entry brings the blog up to date with the project’s progress.
If you look at the Paris drawings, you will see that there are seven pairs of main beams across the hull, not including the otoko, or great beam, at the stern. In each pair, there is one beam above and one below. The lower beam runs between hull planks. The upper beam goes through the hull planks and supports the rail assembly, which supports the yokes for the sculling oars.
Below, you can see a general cross-section of the hull. There are actually three beams running the width of the hull. Since I already have the internal framework, I don’t need the lowest most beam, so I’m calling the one just under the deck the Lower Beam.
There are also several short longitudinal beams show in cross-section below, but I’ll be dealing with these later when I begin dealing with the deck.
