Both areas you describe should have brass drain tubes that will completely drain when underway or on a trailer. It is possible that someone plugged them from the bottom side or covered them completely.
Not sure about a 20' but my 1989 22' has a large well forward of the splash well that has a bilge pump in it. It also will self drain when the boat is underway. It also has a ping pong ball drain to the splash well.
