In “The Cities and the Sea”, add a bullet point:-

* Its Fields, which hold up to five Resources and default to empty.

For each City which has more than five Resources in its Warehouse, remove all but the first five that they added to it. Then move the contents of each City’s Warehouses to its Fields.

In the rule “Resources”, replace “Warehouse” with “Fields” throughout, and add:-

A City (the “Unloader”) may move Resources around in the following ways at any time:-
* From its Fields, to its Warehouse
* From its Warehouse, to the Manifest of a Docked Boat which has the Loader as its Location
* From the Manifest of a Docked Boat which has the Unloader as its Location, to its Warehouse

To the second bullet point in “Boats”, add:-

If a Boat is not In Transit, it is Docked.
