Gather a full crew that are at least level 25. Try to get a man who has "Take Cover". It is best to have a crew of twelve, including yourself. When you are on the actual Black Pearl, you will have to face officers (level 28 and higher). It is best for someone to use their staff if they have one. After the officers, have your "Take Cover" man take the wheel. Then, Light Frigates will appear. Do not waste your best ammunition, but at the same time kill them fast. Allow your steering man to go. He should allow enough space to shoot the towers guarding the drawbridges. Once that is done, go as fast as possible and shoot the last drawbridges as quickly as possible. If you actually made it here then you are in luck. After the drawbridges, have everyone to to the left cannons. The Goliath will appear on the left. Shoot it with all you have. Try to hit it long enough so that your steering man can exit fast.
