My experience has been that CQR is my 'worst' anchor in the locker. FP 43' Cat (disp. 20K lbs.?) carrying 45# CQR, 44# Delta
Fastset, 40# Brittany, and Fortress
mostly in sand, hard sand, some grass/mud around Florida
, the Keys, and Bahamas
. The Delta
sets 95% of the time, the CQR maybe 20% of the time. I have 200' of 3/8 BBB chain.
I will admit that my CQR may have a physical problem. It jams up when the fluke is forced against one of the stops, it takes a big hammer to get it to swivel again. That may be causing my problems with it setting. I think it was a manufacturing flaw.
has never failed to set. I like it a lot, but it doesn't fit my roller/mount, so I manhandle it when I can't get the Delta to hold. I carry 30' of 3/8 BBB and 100' of 3/4 twisted on the Fortress.
The Brittany is used when in a tight spot and need an additional anchor. It's never failed to set, it's just heavy to manhandle.
The CQR is now resting in the garage and I carry the remaining anchors on board.
BTW, I found a good place to get used anchors are the local dive shops. You can pick up a good anchors they 'recovered' for ~20% its new value.
