Would you rather face a North Atlantic storm or a Lake Superior storm in a typical regional freighter?
Short answerThe North Atlantic, because an ocean-going freighter is built to expect severe weather, while a Great Lakes ship may be less prepared for the lake's worst storms.
NotesThe preference is for a North Atlantic storm aboard an ordinary freighter built for that region. Such ships are expected to face severe weather repeatedly and remain prepared for it. Lake Superior can produce dangerous storms even though those conditions are less constant. The choice depends on the ships normally used in each region and their preparation for its worst weather.
