Why do you think shipping by sea to Chicago is difficult?

Apart from it being 1,500 miles from the Atlantic? What's the biggest
container ship you can get that far.

The limit is 225m long, 23.8m wide, draft 8 m, height above water
35.5m, capacity up to 30,000 tonnes. Why do you ask?

Because the most efficient way to ship stuff by sea (even in smallish
consignments that might otherwise fit inside a plane) is to bung it onto
a large container vessel (inside a container, obviously). Sounds like
transhipping it onto a much smaller boat to do the final 1,500miles is
going to be a pain, compared to air-freighting it end to end.
