In my boat I have a in floor bait well, Reelapeelin is right on, if I get water splash on board, when it rains, it fills with water from floor. On top of that on mine you have to pump it out with a diaphram type self priming pump which constantly gets fish and floor crappola in it. Seems around the marina I go out of you see a lot of guys using one of those carry on drums, they are white, come in diffrent sizes and a lot of them either just put a hose type of thing overboard or do an detachable pvc over the stern or gunwhale setup. And because they are round, no corners, water circulates better and fish swim instead of going nose first into corner and dying. The pumps are right on the outside and easy to use and clean
