Ok, so here's what we've found and like so far:
Tidewater yacht marina in portsmouth - pretty big, but reasonable rates, we were quoted around 340+electric to liveaboard
. There's a pool and restaurant, which is pretty cool!
Ocean yacht marina in portsmouth - smaller, right in the city, around 300+ electric
to liveaboard. Really nice dockmaster!
Leeward municipal marina is newport
news - 400/mo including liveaboard fee and electric
. Looks a little rough around the edges.
Fyi - The City of Hampton has outlawed living aboard!
The folks I spoke to on the phone
were very kind, and many were happy to recommend other marinas
if they weren't able to help us directly.
Thanks to AA3JY and HudsonForce for your recommendations!
