Interesting that you first list all pros and cons and then, again, list all pros and cons. Maybe it helps learners to hear everything twice. Your info on the CQR is incorrect though, they hold very badly in weed and grass, and in mud they're useless. You say they reset, but in practice that rarely happens. They usually don't even set the first time. The real problem is that with any wind above 5bft you'll drift or break free. Three weeks ago, on a boat with a sizeable CQR, the boat drifted 200m in sandy grass bottom and 4bft winds, just luck prevented us hitting the rocks. The Bruce is like a CQR, but worse. Delta is comparatively better. The most common anchors nowadays are Rocna, Mantus, Ultra, Delta, at least on sailing boats. Smallish motor boats often have a modern Bruce. You also furor the stock anchor, so used by many fisher men.
By shingles, do you mean shale, like in lake erie?
