What does an anchor do?
In case anyone cares to know about these things:
The anchors sole job is to assist in dragging out the anchor chain. It is only the anchor chain where it meets the seafloor that provides any effective holding effect comparative to the size of the vessel. For reference typically a ratio of around 1:3 is sought to ensure enough anchor chain is in contact with the seafloor. The ratio is different based on current, winds and size of the cable cutter/vessel.
So that's what the manual says.... In real life lazy people do lazy things when they think no one will notice so things like cables get a bit of touchy feely action from 5 ton anchors.
