These photos where taken on the ferry from Bremerton to Seattle, WA, on January 6th, 2010. What's happening here? Are four (4) tugs normal for something like this? Is this a Virginia or Seawolf class boat?
Looks like what we call a dead stick move. It is when a boat is in port with the reactor shut down and the boat needs to change births. They will start the diesel and divorce from shore power. Im guessing the 4 tug is just for maneuverability. The tugs moving sub (that I have seen) are much larger.
