Regarding next generation anchors... Since we changed from a CQR to a Manson Supreme, we have to be more careful how quickly we back down when setting the anchor.
Last summer, using our new Manson Supreme anchor, I had the anchor line already snubbed with an old (but thick) dockline. When backing down the chain went taut and the snubber snapped -- more like exploded. That would never happen with the old CQR. I'm so glad that I had a snubber in place. (I think I was about to do some charging in reverse, to keep some load on the engine. When anchoring, I usually back down with just the windlass keeping tension, without using a snubber.)
So now I worry about ripping the windlass from it's mounting on the bow. One has to be gentle with taking up the slack in the chain.
By the way, I used to always use 2 anchors. I'd even go for a sail and leave one anchor (Bruce) behind with a fender tied to the line. One procedure for pick-up was to drop the CQR while motoring up wind to the fender, letting out chain. Then you'd pick up the fender and the inertia of the (slow) boat helped set the CQR. At the right speed and angle to the chain, the bow will just come around when the slack is taken up. Easy double anchoring. Not sure I'd want to do that with a Manson, since I worry more about having a big jerking force on my gear after it sets. Now I feel that I don't need a second anchor, so the point is moot anyway.
Yes, the Manson Supreme is worth it. Not affiliated in any way.
