If you are looking for something to do, there is the maritime museum which is a short walk from Deltaville Boat Yard. Also, a small "private" beach at the end of Rte 33 (I don't think anyone would mind you walking out to the beach this time of year). I can't think of much else to do in Deltaville, esp this time of year.
You are probably already aware of the Chesapeake Buoy System with live weather conditions. The Stingray point buoy is at http://buoybay.noaa.gov/locations/stingray-point
