Yes... in fact I did exactly that. Went from a genuine CQR to a Rocna. Never looked back.
I also think this is true. I literally seem to be able to just toss (well, heave maybe) my Rocna over the side and throw the line after it. Let the boat drift where it wants. When the wind picks up it digs in like the proverbial Alabama tick !The one down side of the newer anchors is that they are so good, people can get away with worse technique. But this eventually comes back to bite.
I have an interest in anchors and frequently talk to other cruising sailors about their anchor gear and experiences.
Sometimes it works in one's favor. We returned to the US yesterday. It was a clear, hot day as we reached the inlet in Georgia and began sailing up the river. Suddenly the horizon had a black wall on it, and we knew that was a line squall/derecho and these are moving fast, so I got the sails down and engines on just as the temperature was dropping quickly. The wind went to 35kt as we motored at high speed to get to the side of the river where we could drop anchor. With rapidly increasing winds and losing control of boat attitude, I dumped as much chain as I could before the boat skidding back ripped it off the windlass, threw on the chain hook just as the 50-60kt wall of wind hit us. There was no time to set the anchor, or even properly lay out chain - it was all just dumped in the water. That anchor grabbed instantly on ~3:1 scope, the chain went bar tight, and the boat stopped dead with a bit lurch. There was no way to get the bridle on at that time, so we rode on just the chain in 50kts for 30-40min until the wind got back down to 30kts where the bridle could be deployed.The one down side of the newer anchors is that they are so good, people can get away with worse technique. But this eventually comes back to bite.
I suppose you get the anchor for the bottoms you will be anchoring. Nowadays anchoring on the bottoms of LIS southern NE a CQR does the job. Eel grass is hard to anchor in. A nextgen anchor is certainly a good upgrade. But a nexgen is no excuse for not knowing how to anchor your boat. If I were to cruise and do a wide range of bottoms... I would replace my anchor. Chessie may need a nexgen anchor... dunno.I too have dumped an anchor in haste, not as dramatic but stil I was appreciative of the quick set. We have an oversized anchor and have been glad of it a few times. Sometimes thr bottom is just really bad, lots of look rock. We have picked up rocks before, had them plunk back into the water. And one place there was just a skim of sand over some hard pack, therebthe conditions were light and we were really only laying to the weight of the chain and anchor.
I have found anchoring in Newfoundland challenging at times, smooth rock ledges covered with light mud or loosely stuck weed.
When we got our big boat it had a 45lb CQR, I found that to be a joke I some Chesapeake locations, it would just pull through the thin mud, not enough surface area or weight to dig in.
The other tricky situation is in crowded anchorages, it tends to push you to short scope. I want all the holding I can have.
I just don't see the justification to not get the best and heaviest anchor you can. I saw a video of a guy with a Mantus storm anchor. He had to ride out a hurricane so he assembled this oversized Mantus, they can be stored broke down, and survived 70 knots. I am not fond of that solution but he had the solution he needed.
