Andy, we replaced the CQR on the yacht with a genuine Delta, much better. One thing I did notice was that although both anchors are the same weight the Delta has a bigger blade area. We chose the Delta because it was cost effective and comes out well in the various anchor reviews. If money isn't an option then Rocna, Mansom extreme or Spade are 3 more expensive options on the same theme. The RNLI use Deltas btw.
Just be aware that the original pattent has now expired on the Delta design so cheap Chinese copies are also available. The quality of the galv leaves a lot to be desired.
