Harlan, I'm not sure of your experience level so I'll give you a
straight answer. The trick is to ensure that the anchor is set
properly, i.e., firmly dug in. Having the right anchor, rode and
scope is a good start - but if the anchor is not set properly all is
for naught. The whole reason for backing down under power is to
ensure that it will hold under load.

Backing down under power is certainly good a good practice. I do it myself
when the engine is running even though it isn't a very conclusive test on my
boat.

This brings up an interesting historical question which I hope one of the
history buffs among us can answer. What did sailing vessels do before
power? Dragging is even more serious in an unpowered vessel for obvious
reasons.
