Not sure if it's a solo canoe your looking for? If you are considering solo only I would look for a solo specific canoe or dare I say a kayak.
I have a 15'8" Old Town Charles river canoe (Royalex) around 60 lbs. (very stable) and a 17' Old Town Penobscot canoe (Roaylex) around 70 lbs (less secondary stability (= more prone to swimming) but faster than the Charles River).. Both are great canoes! I have made several trips through the Pine Barren's rivers and streams, they are both great boats for it. I have never attempted to solo them though. Being Roalex they are both relatively light and manageable (I can carry them both myself easily). The same boats made of Polylink material would be roughly 20 lbs. heavier.
These boats are also great for long trips and camping, I just got home from the Delaware River. We went 47 miles in 4 days and 3 nights from Sparrow Bush NY to the Delaware Water Gap with both boats 4 people a dog and both canoes loaded to the gills.
I also have an old 15' fiberglass canoe that I rescued and rebuilt, it's heavy, 90 lbs., less primary stability than the others but excellent secondary stability (thinking of selling).
I have a couple kayaks as well, you can never have enough boats.......LOL
None are for sale but if you would like to try them out send me a PM, I have a lake across the street from me or we could take a trip down the Rancocas.
I can show the difference between the boats before you spend your money.
Before you buy, check out canoe and kayak reviews at this site:

It was very helpful when I was looking for my first canoe.
