Lake Superior Boating Guide:
Commercial Shipping

One of the many fascinating aspects of Lake Superior is the large vessels that ply the lake with cargoes heading to foreign ports around the world. These 20-60,000 ton ships are difficult to maneuver, require a long distance to stop and produce a wake large enough to capsize smaller craft that venture too close. Keep your distance from large commercial vessels. Remember, you can maneuver more easily and quickly than they can.
