Transport Ship

Transport Ships can only be built when there are at least two Docks also built.

If all Docks are destroyed or demolished, or only a single Dock remains, Transport Ships can't be built until there's at least a second Dock.

Transport Ships carry up to 270 of any combination of Food, Wood, Stone, Charcoal, Iron, Tools, and Armaments.

By comparison a Dock can store up to 630 of any combination of the same resources as a Transport Ship. Small Stockpiles can hold up to any combination of 240 of the same resources except for Food while Stockpiles can hold up to 990 of the same types of resources as Small Stockpiles.

Transport Ships pick up food or resources from a Dock and does a drop off at another Dock. This allows you to have a colony halfway across the map and keep it supported by your mainland industry.

Transport Ships can automatically move resources between multiple Docks.
