Site details

Tasmania (Wrack) is a dive site located in Canada.

wreck

Open-water offshore site in the Pelee Passage, a historically treacherous channel that has sunk over 250 ships and still carries boat traffic — fly a dive flag and maintain surface cover. Cold fresh water, weather and waves that can build quickly on shallow western Lake Erie, and zebra-mussel-encrusted wreckage with sharp edges. The wreck's exact position is unverified, complicating navigation and ascent planning.
