As I was arriving at work this morning, I noticed this ship docked at Pier 35.
I have no idea what its name is or where it comes from or why it's here or how long it will be here. It appears to be flying a Red Ensign at its stern, but I can't see enough of it to tell which one (click all pictures to see a larger version):
It could be from New Zealand, South Africa, Canada, the Hudson Bay Company or any of several places that use the Red Ensign. Because it's not windy out, the flag hangs in such a way that you cannot tell what emblem is on the flag that would identify its origin. If I find out any more information, I'll pass it along.
[UPDATE 10/16: I went down during lunch and got enough information from spectators to do Google searches and find out that it is "The Maltese Falcon," owned by venture capitalist Tom Perkins. See my later post for further details.]
