Why some captains spend three nights at Clifton

The marina is small. The town is smaller. There is one restaurant within walking distance. And yet many Loopers, having planned a one-night fuel stop, find themselves still there on the third morning — coffee in hand, watching the river move.

A meditation on the stops that turn into stays, and what they tell us about the rhythm of a long passage.

M/V Driftwood Tennessee River · approaching Pickwick

Pickwick approach is unusually quiet this morning — only two commercial tows in the area between Pebble Isle and the lock. Recreational sequencing on the ascending pass took 35 minutes yesterday.

S/V Belle Mer Erie Canal · Waterford Flight

Mast still down for the canal transit. Waterford lock crews running on schedule despite spring high water; expect 4 hour total transit through the flight.

M/V Halcyon Chesapeake Bay · Norfolk holding

Holding at Tidewater Yacht Marina through the small-craft advisory window. Forecast looks favorable for a Wednesday morning departure if the seas drop.

Crossing into Tennessee
