Last night the water was glass and the dock was gone

I'm at the helm and the radar screen is just a flat green line, no buoys, no shore, no weather. The regulars are all in their seats except they're not talking, just staring out the windows at water that's perfectly still. I keep throttling up but the ferry doesn't move, and somehow that's fine — we just sit there, all of us, waiting for a dock that isn't there anymore.
