The car is a bigger problem than the boat. Unless you are a very early riser each day and can entertain yourself until the show opens parking is a pain. Eastport Elementary School
($20/day last year I think) is the best bet for most people.
I recommend getting down here by late Tuesday and anchor
in Back Creek. There are lots of parking options and you can get a water
taxi (or dinghy) to the show.
If you really want a mooring
ball your options are the 5 balls in Back Creek, the half of the main field that is open during boat show
, or the balls well up Spa Creek above the bridge. The small field in St Mary's Cove above the bridge is limited to 35' but there are balls for bigger boats further upstream.
There are Navy
moorings in Weems Creek some people use but the maintenance
is spotty and the locals watch people dragging the Navy's "hurricane" moorings around from time to time.
Other than the three creeks I've mentioned there really aren't moorings near Annapolis
. You would have to anchor
. The challenge then becomes finding a place with shore access to your car and then dealing with parking. There are some anchorages
up South River that work but that really isn't convenient.
Why a car at all? Skip it, anchor in Back Creek, and enjoy Annapolis.
