Take a look at Figures B-D on page 2 of the original rules for some examples. On each waterway, you can put only a single ship. Along the coast, you may only build a ship or a road-never both. Function of Ships Ships work pretty much like roads. A ship connects the points of a hex to the neighboring point.
Several ships make a chain that link two remote points.
If you manage to connect a line of ships that leads you to another open point, you ccan build a settlement. You can then reach islands or remote spots. Moving Ships Ships can be moved. If you have not placed a settlement at both ends of the line of ships it is called a closed shipping lanes. You cannot move any ships in a closed shipping lane.
