I believe it is a grumman: Tight spacing and flat heads of the rivets visible on the stem. What appears to be the stylized letter “G” logo on the front bulkhead. The shape of the front seat supports. And the bow and stern line attachment points that are (rightly) partway down towards the waterline, which I have never seen on a non-grumman aluminum canoe.
Nostalgic.
It’s one of the earliest Grumman canoes, made in the original Bethpage factory by Grumman Aircraft between 1944 and 1952. The “G” logo on the bulkhead is one giveaway. Another is the mildly curved ‘V’ shaped cutout on the cockpit side of the top panels above the bulkheads. On the boats produced in Marathon, the edge of that top panel is just straight across. But this thread is 6 years old and the OP hasn’t been here since, so I’m only noting this for posterity.
Here is another example of the same vintage in good condition:
All canoes track straight when you learn how to paddle them.
Not true.
You can say the same about kayaks. Just because you can make it track straight doesn’t mean it will do so without knowing proper paddling skill. That’s like saying no boat is tippy if you know how to balance. Whatever!
