second thoughts
If you want a canoe even just a little bit, you should have not only second thoughts, but third and fourth thoughts before selling this boat. Morris canoes are among the best ever made, and yours looks like one that is basically in very good condition. It appears that it can be used for a good long time as is unless there are serious problems not evident in your photos), but should you ever wish to restore it in the future, it will be well worth the effort -- you will have a real beauty. But unless and until you decide to restore the canoe, and occasional coat of paint is likely all that will be needed for quite a while.
Wood/canvas canoes are quieter, more graceful and elegant, and just more satisfying to paddle than canoes made of modern materials -- which is not to say that modern boats don't have their place -- where extreme light weight or durability is needed, for example. But for general paddling, it's hard to beat a w/c canoe. A 15 foot canoe is readily car-topped, and is great for both solo and tandem paddling, though it may not be the boat for a lengthy camping trip.
With rare exceptions, used w/c canvas canoes, while generally worth some money, are virtually never worth, in money, the cost of a new w/c canoe. Their value lies, in part, in the fact that they can be made to last almost forever with proper care, and in the fact that even when old, can perform very like a new w/c canoe. And there is the fact that you have a family heirloom, nearly 100 years old, which, with proper care, can be expected to last another 100 years.
People on or near the water rarely comment on an ordinary modern canoe of fiberglass, kevlar, or aluminum. But they regularly comment favorably on w/c canoes, remembering one in their family, or admiring the finish (even when the finish is not so great), or wondering that such boats still exist and can be used.
