This code hack money. Use the code at the shipwright and make a transaction to have 10000000. At the fishmonger there are three instances of money. I think the town fund, what you owe for the ship and your money. I don't know if you make the town fund 10000000 what would happen.
You may want to watch the code and edit the value manually.
