You can't. Buy the least expensive things at one island and sell it at another island to make a profit. Keep on doing this and then buy a larger ship to hold more cargo and make more profit easily.
You can get doubloons by trading, but the price changes very little at one island. The most profit comes from buying cheaply and selling for more somewhere else.
keep trading
none of the games on Neopets currently deal doubloons. You can buy doubloons at auctions, the marketplace ( look in shop wizard.) or trade items for some at the trading post.
Nothing, but you will still lose 10% of your doubloons. Sinking sea creatures is one way to create lots of salvage, but if you lose, you must be prepared to build up your doubloons again.
You cannot evolve without trading, you should just trade with lots of people until you get a gangar
You go to Dragon Cove and buy the most silk then you go to bouffant bay and sell all the silk and then buy the most spice you can then go to Dragon Cove and sell all the spice there then buy the most silk you can and then sell at bouffant bay. Repeat this and soon you'll have lots of doubloons.
There are no shortcuts. You earn doubloons by salvage, by trading, or by sinking creatures and pirate ships. The sea creatures are a prolific source of doubloons, and appear mainly around Dragon Cove. You will need skill and practice to defeat them on a regular basis. (see related trading question)
yes add another game center account
you have to get doubloons by trading grain silk medicine and spice (go around all of the islands on skullduggery)
When you earn or borrow enough doubloons, the shipbuilder is at Dragon Cove just past the trading post.
There are four skilled crewpersons you can hire, and each improves your ship performance in some way. The Navigator and Cargo Master are helpful during the trading phase, and the Shipwright and Cannoneer for pirate battles.The crew positions :Shipwright (Dragon Cove) : 20,000 doubloons to hire, slowly fixes damage without dockingCargo Master (Bouffant Bay) : 15,000 doubloons, increases cargo space of any ship by 50%Navigator (Parrot Port) : 12,000 doubloons, increases ship speedCannoneer (Pirate Outpost) : 20,000 doubloons, increases firing rate of your cannon
What I did, I got 500,000 doubloons and borrowed another 500,000 doubloons.
