Night sailing on the Chesapeake can be a great experience, or a real nightmare. In addition to the previously noted hazard of multiple crab pots, pound nets are also something to be very careful of. These large structures (in my mind they should be called "hazards to navigation") are often poorly lit with road hazard type lights, or not lit at all. Also, many of the lighted navaids on the Bay have the same flashing patterns which makes figuring out where you are a bit more difficult. Finally, in many parts of the bay where it is very narrow (near Solomons, for example) it is quite easy to confuse lights on vehicles ashore with those of boats afloat. All the foregoing are only cautions to consider as night sailing in open and safe waters is wonderful. My advice is to ease into it slowly and carefully by taking short sails as the sun goes down and it begins to get dark. Practice figuring out just exactly where you are and how to get back home safely. With practice, you'll really enjoy this aspect of sailing.
