This campaign mission sticks you with a rust bucket of a boat and you are tasked with beating everyone else money-wise. It sounds hard but really isn't. Keep the same strategy of 40 pots dropped per location. You may want to retrieve the pots, sort and drop them in the same spot again if its still above 1/2 on the crab meter on the screen (It is the little yellow bar shown for each fishing circle on the map). Make sure to head to a dock that can repair your boat after your done dropping and/or picking up pots in an area because your rust bucket will need to be repaired quite frequently.
