'Shrooms
Had similar problem with my H34. I use an 8-lb. mushroom and a large 1/2" galvanized shackle. After anchoring normally, I shackle the mushroom around the rode and let it down the rode with a 1/4" line. I usually let out this anchor "sentinel" till it touches the bottom and then lift it about 1 foot. Never had a rode around the keel since. It also helps the anchor hold, minimizes sailing at anchor and lots of other good things. In very light winds (most of the summer in the Chesapeake Bay) and lower tides, the mushroom ends up holding the boat sometimes.Bought a bronze anchor rode rider that takes the place of the 1/2" shackle that will minimize chafe on my rode but never had a problem with the shackle and chafe.
