Anchoring, chain diameter is a big difference?
Per Dennis''s response 5 to 1 is not short scope and CQR plow anchors will hold well in as little as 3 to 1. Bruces are good anchors but can, like danforths, get rocks or balls of mud and then fail to hold when a plow would have no problem. Once anchoring with a bruce in soft mud it headed to china and I had to use 3 complete tide changes to use the lifting power of the tide to get the anchor out., I was impressed. In similiar situtation a plow would have retreived easier. I do like them in specific instances but plows are better all around anchors.
