I just heard back from the listing person. He said it had been fiberglassed. He was unaware anyone canvassed canoes anymore. It had a single mahogany caned seat which he did not keep. He also said that it did not have a "bottom keel," but there is a "type of keel" on each end that ties the ribs and planks together. Not sure what that last part means. He bought it used in '85 in MA.
