Sea Trade Network

You start as a beginning trader with one boat and six islands around you. Every island has its own character: some catch fish and cut timber, others are waiting for spices and rum. Prices on the open market live their own life and swing by up to ±40%, so a profitable run is something you find, not something you memorise.

Buy cheap, sail the sea lanes around the land, sell dear. Profit goes into speed, hold capacity and better hulls: boat, ketch, brig, fluyt, galleon — up to five ships in your fleet. Once you have mastered a route, hand it to the autopilot and it keeps earning while you are offline.

Storms, demand festivals and supply gluts reshuffle the map every couple of minutes. Scouting opens Cotton Shore and Smugglers Rock, and the trade charter starts the whole business over with a permanent bonus to revenue.
