The Mariners Museum in Newport News, Virginia, has a cypress dugout canoe
with a transom for an outboard!
 
Back in the sixties Robert Burgess did an article in the Virginia Cavalcade
magazine on Chesapeake dugout canoes.
 
There were canoes in the Gambia until recently that resembled the
Chesapeake multiple log canoes. I covered them in my Archeological Society
of Virginia quarterly bulletin article about creolization.
 
London Archaeologist magazine had a cover photo of a dugout canoe on the
Thames, replicating a medieval example.
 
I took the lines of a dugout canoe which was published in the Virginia
bulletin and in the journal of the Nautical Research Guild.
 
If any of these interest you, I can send exact citations.
