11:22 AM: Just in from Washington State Ferries:

The Issaquah has been taken out of service to repair a water pump seal leak in the #1 engine. Repairs have been scheduled between the morning and afternoon commutes to minimize impact to our customers. Two-boat service will continue on the regular schedule with the Cathlamet and the Sealth until repairs to the Issaquah are completed. The Cathlamet departed Vashon for Southworth at 10:45 am and the Sealth departed Vashon for Fauntleroy at 10:15 am to begin temporary service modifications.

We’ll update when this changes.

2:44 PM: Repairs aren’t done yet; WSF continues 2-boat service with Cathlamet and Sealth: “The Cathlamet runs the #1 position with the following departure schedule … 2:50pm SW-Va-Fa, 3:35pm Fa-SW, 4:05pm SW-Fa. The Sealth remains in the #2 position with the following departure schedule … 3:00pm Fa-Va-SW, 3:45pm SW-FA.”

3:24 PM: Back to three boats – details here.
