First, you spot a ship on hd-sf.com. Then you look in the upper left-hand corner, where it lists the ship’s name.Then you put the name of the ship into Google. It will direct you to a site like Vesseltracker.com, which gives you information about the ship, and often a photo.You also can see ships on the Sausalitocam, though it gives no info.
This is the MSC Voyager, 843 feet long.
This one’s from a webcam high in the Sausalito hills. Same two vessels, a little later, from hd-sf.com.
Sometimes it’s fun to look at the webcams when there’s no ship at all. A bay view for anyone with a computer and internet connection.
