Ontario’s Popular Paddlewheel Shipwrecks

The view of a set of huge paddlewheels, rising from the lake bottom, is an awe – inspiring sight for divers. In this presentation we will look at three popular wrecks accessible to recreational divers.

The “Comet’ and the ‘Cornwall’ both located at the eastern end of Lake Ontario near Kingston, Ontario and the ‘Rothesay’ in the St. Lawrence near Prescott, Ontario. We will examine the history of these three vessels, the cause of their sinking, still images of each wreck and conclude with a short video dive on each wreck
