This is where icebreakers come into their own, by clearing the way and escorting commercial vessels through these treacherous waters. But seasonal conditions can make it difficult for them to do so. Most modern merchant vessels are designed to be able to navigate icy water in areas like the Baltic Sea, the Saint Lawrence Seaway, the Great Lakes, and such.
