I am looking to replace my CQR anchor of my Heritage 47 Classic. I had a Rocna anchor on a previous boat and loved it. That type of anchor, with a roll bar, cannot fit on the bowsprit. I'm looking at a Spade (66 pound) or Quickline Ultra (60 or 77 pound)anchor but I'm not sure how they will adapt to the bow. Does anyone have experience with either of these anchors?
