Once you are sailing among the five outlying islands, you will collect doubloons (cash) and cargo as salvage (it is just floating in the water). You will buy and sell cargoes, trying to make a profit by buying low and selling higher. Each of the islands except Parrot Port has a cargo you can buy very cheaply.
Once you have enough doubloons (3000 for the smallest new ship), you can buy one at the Ship Shape shipbuilders shop at Dragon Cove. Used ships have a small resale trade-in value.
You go to Dragon cove, and buy your ship from the ship guy.
You buy it at the ship builder's place.
skuldergy island
you either buy it or get a member ship to buy special items.
u need 2 buy the bobble head in the poptropica store.
You dont trade ships you buy ships
First you have to buy a ship from the Chinese guy on the Chinese island. Once you do that your new ship will have a cannon in it. Your raft does not come with a cannon You may need to take out a loan to buy a ship :)
You have to go to dragon cove, and you will see a doorway. go in it and tell the guy you want to buy a ship. !ok
You can either do the Gulliver's Travels mini quest, (if it's still out) or you can buy the thing that makes you bigger in the store with credits that you earn by completing islands. (but the one that you buy makes you bigger than the one that you earn.
if your talking about on skullduggery island you have to save up your money to buy one. (poptropican money, and not in the store)
Once you've gotten to the Japanese island you go to the guy selling ships and if you have enough money you can buy a bigger ship.
The ship you signal is the ship that gives you the island medallion.
