OpenFront Trade Ship Calculator — Gold by Distance

The curve is a sigmoid that bends sharply near distance 300. Try short distances to see why clustering ports is wasted gold.
The curve is a sigmoid that bends sharply near distance 300. Income at distance 100 is roughly a tenth of what you get at 300. Spread your ports as far apart as the map allows and aim them at distant foreign ports.
