Shipwrecks show through Georgian Bay water clear enough to read their decks from the surface.
The hull appears below the glass-bottomed boat, whole and pale on the lake bed. Above the water, flowerpot stacks stand offshore like abandoned chess pieces.
Fathom Five protects a drowned fleet in the clear water off Tobermory, where glass-bottomed boats cross the wrecks on the way to Flowerpot Island's sea stacks. Divers get Canada's most accessible cold-water wreck field; walkers get island trails and the lighthouse. The harbour town serves Georgian Bay whitefish when the boats return.
