That is not a tripping canoe. It might work for what you’re talking about, but so would any other canoe. That is not a boat that you will be able to portage very far. Unless you want a boat that you are probably going to feel like replacing you will probably need to spend a couple hundred more.
I think there are three good boats from old town that meet your requirements with the exception of being a bit more expensive. These are three layer polyethylene boats that will last a lifetime:
Discovery 169, $1200. This is an excellent river tripping boat for the price, I would have no issue using one anywhere. This is going to be a better white and rough water boat. It will be very seaworthy and maneuverable, at the expense of needing a little more skill to paddle straight.
Penobscot 164 ($1300), and the Penobscot 174 ($1400). These are better flat water straight line boats, but will work up to class two rapids. These would be easier to paddle in a straight line than the 169, but less manuverable. The 164 would be fine for short trips or less gear. The 174 would be great for a long trip, one with more gear, or bringing a dog.
There is also the Discovery 158, $1100. This seems to me like your standard utility canoe. Probably not the best in any category, but definitely a better boat than the Saranac. It won’t track as straight as a Penobscot, and not be as seaworthy as a 169. This isn’t really a tripping canoe, but would work fine for mild trips where you don’t have a ton of gear.
I think you would be much better off getting a used boat than a Sanarac if cost is a big concern. If it were me and I was only going to own one new canoe it would be a Discovery 169, I think the is the best all around boat Old Town makes.
Edit: I just realized that you will be using the boat solo. You can solo any of the boats I suggested by sitting in the bow seat and paddling the canoe with the stern going forward. If most of the paddling you are going to be doing is solo, then I think the Discovery 158 would be the best option. The other ones are getting pretty big to solo. Plus the smaller displacement of the 158 won’t matter if it’s a solo and carrying less weight. I have been heavily considering getting a 158 as a Solo tripping boat. I think it would make a better solo tripper than tandem tripper. The 158s are also the easiest one to find used, and you can get one in decent shape for a comparable price to a Sanarac.
