Looks like an Old Town with outside stems, maybe closed gunwales given the outers look like caps more than rails? Where are the shots of the decks seats and thwarts? Come on , you've been around here for a while! Sure looks easier than the Rushton, go for it! Some shots of a ridgeback would be great too, always liked them but i've only ever seen one, and the owners said it was a great dog but stubborn!
My guess is an Old Town Otca. The decks would have a coaming attached to the curved rear edge and notch into the inwales. The notch should be obvious in the inwales.
