One thing I always use to love doing is I would get at least 11 officers to insure I have enough for 4 ships, I would pick a good one for chasing such as a corvette, and I would just go out and capture a bunch of enemy ships and then sell them. Second easiest way to get rich. Once you are at high levels it starts to become hard to not accidentally sink ships before you can board them, but on the flip side it makes it easier to accomplish the first easiest way to get rich. Conquering forts.
