A correction to that previous post.

: The guy you want to talk to is Ralph Frieze of the Chivagoland Canoe Base. He
: is, or was, the leading maker of Voyageur canoes in the US. . .

His name is Ralph Frese, and the website of the store has an e-mail address. link to the store is:
chicagolandcanoebase.com/contact.html

That website makes no mention of the larger canoes Ralph made, but does have a brief mention of the birchbark-replica voyageur canoes he makes from fiberglass.

Hope this helps
