I would encourage you to look north of Annapolis
for the Tyson's commute. I live in Great Falls (next to Tyson's) and keep my boat in the Maryland
Yacht Club in Pasadena. With the new cross county connector, you get to avoid most of the 95/495 beltway madness. The Maryland
Yacht Club is also one of the best deals going with some of the lowest rates in the Bay (and there are live-aboards there also.)
Good hunting ...
