Well, yes, but with satellite observation, most ships avoid bad weather
most of the time. Its only when storms are the norm over the entire
ocean that subs would be more economical. Additionally, subs as cargo
carriers are most effective for iced-over seas, like the arctic. If the
arctic ice melts, the sub advantage is obviated, as we alre already
seeing with cargo ships plying the Northwest Passage to eliminate 5,000
miles from the europe-tokyo routes that normally pass through the Panama
