Be invisible
First go the ship, go up where the mast is. There will be many barrels that you can push. Starting from the right side, push the barrel that's in you way down enough so that you can get around it and push it up, until you can't push it up anymore. Then get on the right side of the barrel by walking out of that area from the left side and walking around. Now push the barrel left up against the mast about half way up. Go back around the mast to the left side, and push the barrel to the right. If you did every thing correctly, you should see the barrel moving, but you'll be invisible!!! You will stay invisible as long as you stand still, once you do something else you will see your self as regular.
