To state the obvious, the rpm used to back down depends on the engine. My Lehman cruises at 1600-1800 rpm. When I back down using the Lehman I go to 1000 rpm. My Yanmar auxiliary engine cruises at 2000-2400. If I used the Yanmar I would jump up the rpm when backing down to perhaps 1600 or so.

We have a Rocna and we still always back down. My preference.

To be fair, I set the hook depending on the situation. Where I am this morning (feeder canal off the Okeechobee waterway) spooling out 50' of 3/8" chain without the anchor would have held the boat.

With line we use idle reverse to get the boat moving and simply allow it to check against the anchor .A tiny stern anchor is insurance.

Sure we always have a trip line , but the effort and time of yanking a deeply buried anchor is a waste.

Full throttle reverse with a 6-71 and 32 x32 prop , no way!!!

You don't want to know how many times I have seen people use that technique.

The worst I ever saw was a fellow on a MacGregor 24 or 26... he stood on the bow of his boat and THREW a fake danforth off the bow. It landed about 20' from the boat. Then, using 3/8" line he tied the anchor of to the bow.

It was ugly.

When we spoke later in the day I asked about that. He said he'd "used this method all the way down the Mississippi and it worked fine"

Then the tide changed and guess who dragged?

On another front:
I had trouble with a too heavy chain, laying a 25 pound plow on it's side. I was using 3/8" (25') and the doggone plow did not set. I suspect it was because the weight of the chain was such that it prevented the anchor from digging in.

Removal of the 3/8" and back to all 1/4" chain and no issues whatsoever. Until I dragged.

That's when I moved from 25 pound plow to 33 pound Rocna. After the half century mark I need my beauty sleep! With the Rocna I don't worry about me dragging

Doing the same. 2x FL120, all chain rode. Start backing at idle, when chain becomes stiff we increase gently to 1000 rpm as a max.

wadden that's what I usually do.

Another thing in addition to the size of the engine is if one is overpropped. Rpm w no way on is way different than when the boat is propped to rated rpm but when overpropped also it takes even less rpm yet to load a prop. Time w tension on may be more beneficial than brief tension. Brief tension may be more likely to promote an anchor to break out than a steady "soaking" tension.

If one experienced a reversal in light breezes the anchor would be set backwards holding the boat. If more wind came up the anchor may flip over on it's back and need to reset. Very high setting performance like the SARCA has shown gets very important. If one pulled straight on backwards or very close to that an anchor would tend to flip and not rotate. Some more likely than others ... a Danforth for example w it's stocks sticking out.

Since you really don't NEED to back down on any anchor that's not say'in much for the Rocna.

No, No, No! A true anchor setter type person would only use a Mantas.

Oh no, now you tell me. I just bought a new Vulcan. All I know is it is bigger than the old Bruce and lifts OK off the dock. Can't back down on it, the boat is tied to the dock.
