Gotta check in with the Sausalitocam. Out in the fog you can see the Overseas Sifnos, 600 feet long.
Here’s the Cygnus Voyager, 902 feet long. These ships constantly transmit their identity and measurements, which are picked up and put on this website: http://hd-sf.com/. If you click on the ‘Live Map’ tab, then on the ship markers, you get the info.
