Ships are only useable if there is enough water on the map.
Even if they are the slowest class of vehicles in Industry Transporters, they excel in transporting goods over a long range, as they have the lowest fuel costs and quite low repair costs and a gigantic cargo.
Same as every vehicle class, ships also have 2 kinds. One that is even slower but can take a whole lot more cargo, and the other quite fast while carrying quite a load.
