You are the captain of a big ship and you are going to sail from one port in Brazil to another port. There are many different places where you can stop and where you can visit, but in order to get to them you need to sail and get to the next port. But you have to be careful, because if you hit a ship or a boat you will lose the cargo that you are carrying, and you will not be able to continue your journey.

So, the best way to avoid losing your cargo is to be careful and make sure that you do not hit a boat or a ship.
