When you are actually dropping the anchor off the bow are you controlling its descent by holding the chain and slowly letting it run out or are you just letting it drop until it hits the bottom and then maybe manually playing out rode?
there are variations of the simple and basic way it HAS to be done.
given that the ground tackle is big enough and proper for the bottom and conditions, and as long as the chain or line does not get wrapped around or piled on the anchor, and has been payed out between the anchor and the direction the boat is moving in reverse, you cant go wrong.
my variation is, when deploying the anchor I am moving slowly
under power in reverse, not just coasting or drifting, and I will let the anchor fall pretty fast as im letting the chain slip thru my hands, and as soon as I feel the anchor hit the bottom I will stop the fall of the chain briefly.... then I will let about 10-15 feet out slower as we are moving away from the anchor....
once I know the chain is not piling on the anchor, I let it go freely (thru my hands, and not caring if it piles on itself) and count the markers as it pays out... when I get to the marker I want, I stop it and quickly snub it down.
the chain will pay out faster than the boat is moving and allow you a few seconds to do this without any load on the chain.
when the boat gets to the end of its slack you will feel a very definite and unmistakeable hook up with the bottom.... at this point there is no need and would be redundant to power into it in reverse, as the momentum of a 10-15,000lb boat setting the anchor is more than what the prop will give you....
its NOT a sudden violent jerk, but a very quick soft slowing then stopping of the boat as the anchor grabs and digs deep.
I always use a 4-1 scope for setting the anchor, and almost always let out more after it has set.
this is much better practice than letting out 250ft and then finding out you have dropped on a bed of grass

.... and after doing this a couple times in sucession, you soon learn to get the anchor set before letting out more than necessary for digging in.
if you cant be quick about snubbing the chain, it may be best to
drift backwards and let the chain out in the same manner as I
suggested, and it will allow you a bit more time for the task.
keep in mind that the initial snubbing of the chain/rode to set the anchor, can be as quick and simple as wrapping it a couple times around a cleat.
once the anchor digs in, you can then take the time to reset the chain or secure it in whatever device you have to secure it in, but no matter where or how you secure it, if it wont take the power put on it by the momentum of the boat setting the anchor to begin with, it should never be used as the point to ever be trusted to hold at any other time...
