We returned the line of the gunnels to what looks correct ...that is usually pretty accurate... and it comes out to 15 x 31 x12. Technically speaking it may be a model called a Chinook, but it is really hard to say. This boat has a couple of unusual features. No keel, and there are no holes in the ribs to show it ever had one. Also, tapered ribs which no one can really make sense of either. It has fairly wide planking too which indicates pre war construction, when they still had trees big enough to do that.
It does have the crowned decks with the heart shaped lobes that are typical of a Canadian as opposed to Pete or Chestnut, and the number stamped in the stem seems to work for that too. There was no decal or builders plate affixed to it when we got it so it is a very educated guess from a couple of professional restorers we know as to what it is.
What it IS, is a really good boat that should paddle very nicely. We are taking it with us next week to paddle around a bit when we are on holidays to check it out.
