Fitz’s photos refreshed my memories about the Brodbeck and thought I would clarify and add a point or two.
Re how the ribs and inwales were joined. Describing the ribs as set in a pocket of the inwales is really not accurate, as the rib tops are exposed (open gunnels.) What he has done though is half notched the inwales, so on the underside, the rib ends fit in a beveled notch on the inwale. The bottom side of the inwale is wider than the top of the inwale by the thickness of the rib to allow for this “half-notch.”
Also, if you look at Fitz’s pictures of the canoe’s end, you can see that the inwales and outwales sit together flat at the ends: no cant rib ends sticking up to separate them. To do this requires more fiddling with the shape of the inwale. On the first photo Fitz posted, on the rib on the left hand side of the photo, you can see how the last rib end fits in yet another inwale notch. Note that the outwale is not notched to overlap the sheer strake plank. The top edge of that plank is exposed.
So it’s sort of a mix of open and closed gunnel. Open most of the length of the canoe, but closed at the ends.
The seat cane is original. So is the seat cane on Bill Conrad’s Brodbeck (the only other Brodbeck I know) and its about 100 years old.
