11:50 AM: From Washington State Ferries:

The M/V Sealth is out of service due to unscheduled maintenance until further notice. The Fauntleroy/Vashon/Southworth route will operate under the normal 3-boat schedule without the #2 vessel departures and arrivals. Real-time departures and arrivals of the M/V Cathlamet and M/V Chelan can be viewed on www.wsdot.wa.gov/ferries/vesselwatch.

It was just yesterday that the route returned to 3-boat service after a week with two.

1:30 PM: The problem was brief and the run’s back to three-boat service.
