You don't mention your air draft
. There are a couple of other marinas
in DC that might work
depending on your air draft
, that size Jabins puts you on the floating docks and is likely prohibitively expensive. Port Annapolis
may have something, but 65' is pushing it. Might be worth a call. It's about 50min to Arlington on average. Rush hour might be much worse.
You might check out Edgewater. There are a few marinas there that might have T's available.
There's Belmont Bay in Woodbridge, but they're usually pretty full too.
You're going to have to work the phones, unfortunately. Good luck!
