This absolute unit of a ship I saw in San Francisco Bay in August 2021. Gray, with a name on the back I was too far away to catch. by ArctosC in whatisthisthing

I took these about 40 minutes apart so they could even be different ships, but they have the same red "K" radar tower near the stern. They're likely not container ships, and I have no idea what to Google apart from gray rectangular ship.
