So basically, what you buy cheaply is sold for a lot at the next island in the circle in a clockwise rotation. The only exception is that there is nothing cheep to buy at Parrot Port and nothing expensive to sell at Golden Harbor.
You can easily go back and forth between any two islands except Parrot Port and Golden Harbor. For an example, if you buy Spice at the Pirate Outpost. If you sell it at Dragon Cove, you can buy silk which is cheap there. Then you can sail back to Pirate Outpost to sell the silk even though you won't get the most money out of it. The problem is the distance between the two. You can try the same thing with Silk and Medicine between Dragon Cove and Bouffant Bay, which is closer. But in both cases, staying in thesame locations too long will attract Sea Monsters (Dragon Cove) or Pirates (Pirate Outpost).
Prices change when you leave the island. So if something that's supposed to be cheap is higher than you want it to be, get on your ship then immediately dock again. The prices will be reset.
Golden Harbour. If you carefully sail around the rocks there'll be al ot of salvage.
The amounts of cost for medicine, silk, spice, and grain are changing all the time. The best way to get profits is to go to each island clockwise, buying the cheapest thing and selling it at the next island for a lot of money.
Generally, sailing anywhere near the Pirate Outpost will bring him out. When you have all 5 map pieces and the new island appears, sail past that island and Captain Crawfish will soon attack. You will need the Phoenix Warbird, the Cannoneer and likely the Shipwright to best him in battle.
This is a long process (at best 3 to 5 hours of play). There are no shortcuts.(see related question)

the best way is to go around and and collect "salvage" around the different islands in the water, then go to the dragon Cove (the Chinese place) and give all to the trading person. do this until you have enough doubloons to buy your ship.
