I used to own that canoe. It is a four-plank-per-side batten-seam wide board canoe. The design is distinctly Canadian. "AuthenticBoats" is John Summers former general manager of the Canadian Canoe Museum. Just about every canoe manufacturer from the 1870s through 1900 offered decked canoes of some sort. The difference is that none of them used the construction technique that yours exhibits, which would be typical for a home-built canoe. Your best bet is still to compare the lines of yours with the various canoes in Stephens's book.
