We had an amphibious vehicle that pandered to the tourist trade in Ottawa about 10 years ago. The vehicle had been modified in the Ottawa area and I believe went by the name of Lady Duck. As it happens, it also sank on entering the water with the loss of at least four lives. It dropped out of sight and I next saw it at an auction yard. I have no idea where it is now.
