"I imagine it would!"

She starts pinning string to the map, going from London (which gets a gold pin) to the Cumaean Canal (blue pin), to the Iron Republic (black pin), the Melting Isles (green), Port Carnelian (gold), the Isle of Cats (blue), Nuncio (blue), the Chelonate (gold), Polythreme (gold), the Salt Lions (gold), Demaux Island (blue), Hunter's Keep (blue), and finally back to London. Plain steel pins get added to divert the route around islands and obstructions.

She scrutinizes the route for a moment. "Gold indicates trading, black for refueling, blue for port reports and green for... shore leave?" She guesses.

She nods. "Just so. The beaches are really nice. Shore leave is also available at Port Carnelian and London, sometimes at other trading ports, and occasionally at report ports."

She nods. Buy wine at Wolfstack, sell at Carnelian, then buy Sapphires, sell at either Chelonate or Polythreme? She forgets the prices. Perhaps ship some Stygian Ivory? Who buys that? Wolfstack? She forgets. Or remembers? Why does she think she knows this? She shakes her head. 

Her eyes wander around the chart. They snag on Kingeater Castle. Something nameless fills her belly with dread and sorrow.
