Less than half are taken over by the show...
but the real problem is that so many folks come in for the month and take a mooring. There is a good week and month price, and lots of liveaboards/cruisers come and work the shows and take a mooring for the months Sept/Oct enroute south. Vacancies are very hard to come by. Or course, the achorage off the naval academy is packed with others who just anchor.My suggestion: stop off up in Balitmore. Great marinas, great services, and it's a pretty easy drive down the Annapolis. When it's showtime down there, things get crazy. Heck, houses rent for $1,000 a night. I can't imagine what a slip would go for.
