We have been quite pleased with our 15' OT 50 pounder. We use it for day-trip paddling on lakes, streams, and bogs, mostly in central Maine. It is fairly roomy and could be suitable for short camping trips, but not if you are a heavy packer. Lightly built, it is not a canoe you would want to use for a lot of white water paddling. Even with a keel, it is quite maneuverable and responsive, and with a fairly flat bottom, stable. It's fine for solo paddling; when paddling alone, I sit backwards on the bow seat, and put a rock or some other bit of weight in the bow (the normal stern) for better trim.
Our new (for us) 16' OT Ideal is prettier, more tender, a bit faster, a bit heavier, a bit roomier, a bit sleeker, and a bit less responsive. Being heavier and lacking a center thwart, it is more awkward to handle on land. It is quite difficult for one person alone to load on top of the car, and a chore even for two people.
I can easily load the 50 pounder onto the car top myself -- even more easily after I replaced the original center thwart with a portage yoke, and it is readily moved around on dry land. Ours has a couple of cracked ribs a hole in the planking, some dings in the gunwales, and has needed a new canvas since we got it -- but nonetheless is very functional. I've recaned the seats, made the portage yoke, and played around with three different paint schemes -- and it will get a full restoration in about a year.
The Ideal is replacing the 50 pounder for cruising, but we still use the 50 pounder for smaller streams, or when we want to quickly throw it on top of the car for a short afternoon paddle in a nearby river..
Not for serious white water or expedition camping, but otherwise, it is a great all-around canoe.
