It is posible. The canoe has sustained some significant damage over the years. There is a serious looking patch job on the bow and four patches where the original thwarts were. The damage and subsequent repairs may have distorted the original dimentions a bit so it is possible that it used to be narrower.
So, after reading a thread about someone purchasing a MR Slipper without thwarts and that they were able to pull the gunnels into shape… I decided to give this canoe a squeeze. The following are pictures of the alterations. After I cranked on 4 tie down straps, trimmed and then reinstalled the thwarts I was pleasantly surprised. It is now a more realistic solo canoe. I realize that I may have overdone the narrowing, but I didn’t want to stop at a 32" beam. Cannonball, I suspect it is a Courier, but I have not heard back regarding the serial # from Confluence
Note that when you pulled in the gunwale width the length of the boat at the top increased. The length of the boat at the waterline did not increase because there is no flexibility there. The result is flattening of the keel line. The ends of the boat where it is narrow and more rigid do not flatten, so all the flattening occurs in the middle section resulting in a hog-back keel line. This may not be noticeable immediately, but over time it will happen. Conversely, if you widen the boat at the gunwales you will add some rocker to the keel.
I really hope you put the gunwale width back to specs. It is a great boat and in good shape, You will hardly notice the extra inch or width.
It is almost certainly a Courier. That canoe has been rerailed. The inwales and outwales are sandwiched on the hull. Although MRC did sandwich the gunwales on their Royalex canoes (as did most makers), on their composite boats the gunwales were rabbetted so that the top of the hull was not visible between the inwales and outwales. Since it was rerailed the thwarts are probably not stock and the inset deck plates do not look stock either. The canoe may have been pushed out a bit when rerailed.
Also, MRC usually measured beam at the molded hull, not from the outside point of one outwale to that of the other. So in your boat the beam of the canoe in your first set of photos is more like 33 3/4". Assuming the other end of your tape in the last set of photos is against the outside of the outwale, you have now pulled the beam in to about 29" or so, which I agree is a bit much.
I have seen quite a few composite Mad River Canoes and have never seen one stock that did not have rabbetted gunwales. This document would suggest that sandwiched wood gunwales were only used on Royalex MRC hulls:

Just my 2¢ worth but never saw a Curtis with sandwiched rails…owned a few going way back.
You are correct about my Lady Bug - no exposed hull edge. Now you’ve got me wondering which of my past boats that was, since I didn’t have that many with wood gunwales.
