Try buying every ship in order unless you can afford one higher than the one your saving for.
You need to buy larger ships as you can afford them, and accumulate enough doubloons to buy a Phoenix Warbird (500,000 and you can borrow another 500,000 from the Golden Harbor bank. You should also hire the Shipwright (Dragon Cove) and Cannoneer (Pirate Outpost). When you have assembled the 5 map pieces, and have your Phoenix Warbird, you can sail near the Pirate Outpost and Captain Crawfish will eventually show up.
anywhere on the map
To get the map piece, go along the water until you find the floating statue. Climb on it to reveal the Mallet. Push the old fisherman to the right, past the giant Bell Gong, to near the first barrel. Use the mallet to strike the bell gong, and it will scare fish from the water. When he catches one, the map piece is in its mouth.
hire all the people you can!
If you stray into the sea area below the Pirate Outpost, you may be attacked by Captain Crawfish. In order to beat him, you need a ship as powerful as his: the Phoenix Warbird. You will have to buy smaller ships as you can afford them, so that you can earn doubloons more quickly. When you have 500,000 saved up, you can borrow another 500,000 from the Golden Harbor Bank and buy the Warbird. Once you have this most powerful of ships, you can attempt to sink Captain Crawfish. If you succeed, you can get the location of the Buried Treasure from the Governor.
To trade and sell on island on skullduggery island you first must be on one of the 5 islands and walk around you should see a post that says " TRADING POST"
It takes approximately 25-100 "days." Everytime you land is counted as a "day" in Skullduggery Island.
You don't buy cannons. The cannons are part of the more expensive ships that you buy as part of the game. Each larger ship has more firepower. When you have the largest ship, the Phoenix Warbird, you should also hire the Cannoneer from the Corsair Cannon shop at the Pirate Outpost. His salary is 20,000 doubloons, and you may hire him onto any ship. He lets you reload faster when battling pirate ships and sea creatures.
It costs 1,000,000 doubloons for a Phoenix Warbird, essentially the same ship that Captain Crawfish is sailing. It is the only one that can defeat him (you need the Shipwright and Cannoneer as crew). You actually only need 500,000 or less, because you can borrow another 500,000 from the Golden Harbor bank, and when you win, you do not have to pay it back. Once you start buying larger ships, getting this huge number of doubloons becomes far easier. You should buy the next larger ship as soon as you have the doubloons, or you may lose them.
You should buy the NAVIGATOR (12,000 doubloons) in Parrot Port. She increases the speed of your vessel.
No, they do not.Most players will not repay their last loan, which can be up to 500,000 doubloons to buy a Phoenix Warbird. Since the only penalty for not repaying an overdue loan is that you cannot buy a larger ship, you would not be affected at all.You should always pay back a loan as soon as you can because you pay 5%interest for every "day" up to 20 days. However, since a "day" only passes when you leave one island and arrive at a different one, you can limit the number of days that pass as well (leave an island, collect salvage, and go back).
After you get all of the map pieces, go to your inventory and click to examine the map. The map would assemble automatically and a secret island would reveal it self on the map, named Skull Duggery. You could sail there to battle Captain Crawfish (one of the four villians!), but before that, you should get the battling ship "Phoneix Warbird", as well as hiring most of the crew members. (Because even with the Phoneix Warbird, it took me about 3 minutes, because it is really hard to aim while both ships are moving!)
