Stack captain scores
You can add more than one person, other than the Captain, onto your
other 3 ships. All of their scores will stack with that ship's
captain's score. There are 2 different ways to do this. The 1st
method is at the "Open Sea" screen (where you can see all of your
ships), get close to another one of your ships and a swap cargo icon
will appear. Go into the swap cargo menu. There is an option to
switch captains. Under this option, there is a screen that has 4
slots. One of them is the captain of that ship. Click on one of the
other 3 slots, then assign passengers to each one. When you do
this, they dissapear from your passenger list. You will need to get
more party members at the tavern if you want to fill up all your
ships. Do not sell the ship with the other 3 crewmembers still
on it. You will lose anyone that is still on board. The 2nd
method is to capture a ship and do it when you assign a captain to
the captured ship.
Hint: Ding Dong Ditch:
Go to a door in any part of the game and press Action. Your
character will knock on the door, then you can run away.

Avoid officers and swordsmen
After killing rampages, swordsmen and officers will try to kill you.
If you have a group of officers and other swordsmen coming after
you, go to your ship. Get on your ship, then dock again. No one will
be attacking you anymore.

Money $$$ Money
Go to any of the loan sharks and ask for any amount of money. You
can go to the box in his office and drop your money in it. Now, go
up to him again and ask for more money. Continue to do this until
you have the desired amount. Even though he says that he has ways of
getting his money back, he never comes after you

Go into other people's houses and steal their items. They have
things such as potions, gems, rings, and other expensive items. You
can also look in isolated barrels, pots, and other containers around
the cities for more items. If you walk around in towns and into
places like the areas behind houses, alleys, corners, and similar
places you can find items that seem to have been dropped. *** If
you walk around at night, you can see little specks of light on the
ground, and these can be those items.

Glitch: Unlimited money
Raise your Commerce to 10 as soon as you can (use all the points you
get towards it). Now, go to a tavern and chat to an officer that
you can hire and ask him "How much are you asking?". He will respond
with a price. Now, say "Isn't that a little too much for you?". He
will reply "I guess you are right" and then offers less. Say "Nah,
still too much" ( or something to that effect) and the dialog box
will close. However, the next time you chat to him, the price will
be the last price he offered. Repeat this until he responds with a
negative number (i.e. he will pay you for you to hire him).
