12:20 AM: From King County Department of Transportation:

The King County Water Taxi West Seattle/Downtown Seattle route is expected to return to normal operation Sunday, Oct. 17, pending the U.S. Coast Guard’s inspection and approval of repairs made to the vessel Melissa Ann. Service was cancelled Saturday because of a mechanical problem.

Here’s our earlier coverage. Meantime, on the same webpage that’s been tracking this, you’ll find word that there are ticket machines at the Seacrest and Pier 50 docks (Vashon too, for that route) that will start operating on Monday, taking credit/debit cards.

8:52 AM UPDATE: The county confirms the Water Taxi is running again – and the live marine-traffic map confirms this.
