> It isn't unreasonable to just stop at a port every night Is it? How many more deep water ports would be needed if every ship had to stop every night? What about if you're passing hostile or undeveloped countries? What about when you need to cross the Pacific or Atlantic? Cargo ships move at maybe 15mph - there's definitely huge parts of the world that don't have a well equipped deep water port every 360 miles. Even major western countries only have a handful of major ports.
