I would stay put in AC until you get the right conditions. We have used Kammermans there if you want to be connected to land in Clam Creek and dont want to pay for the Farley Marinas 5 bucks a foot. You can also anchor across the channel from Clam Creek, but the current does roar through there.
Just FYI, When entering Clam Creek in AC, the very first left turn brings you into Gardners Basin, and the Municipal marina. I think they charge about $1.50/ ft.
