Ship Movements

[RedmondCruiser]

Can someone please explain why the ships seem to be constantly shuffling around.  They don't seem to stay in the anchorages but seem to be milling around every few days.  If they are doing 2 or 3 knots then I assume they are loitering and not burning too much fuel, but several ships seem to be going much faster and in so doing burning up fuel. Aren't they supposed to be at anchorages and saving money.  Am I missing something here ?

To support basic functions, like making water and legal disposing of waste products, movement is important, and they have to be certain distances from land.
