Inspired by a recent question. If I want to cross the Atlantic Ocean in a boat, what are the shortest and longest possible crossing sites?
Where crossing = going from one continent to another where there is no land bridge (i.e. You can walk from North America to South America)
I first thought about going from Southern tip of South America to Antarctica, this is around 600 miles (1,000KM). Not sure if that would 'count' as crossing the Atlantic the Pacific, both or something else.
