YOU GUYS THAT SENT ME A PM ABOUT THIS HERE YA' GO-
I spoke to a few people about this and I was surprised how many didn't understand so here it is: Most "plow" type or Bruce have a hole at the bend or elbow, also the main hole at the end. The hole at the elbow is designed for a messenger line w/bouy, BUT, no one needs to carry the extra messenger line. Attach your chain directly to the elbow hole with a horseshoe ring/bolt/etc., now the chain lays parallel along the longest shaft of the anchor. At the end hole of the anchor shaft -one loop of halibut cord, -tied to one chain link and the hole, not two loops, just one. The cord now attaches the chain in the logical fashion to the anchor. If the anchor hooks under a cable or solid rock shelf, the strength of the halibut cord on the chain will break with all the tugging before your anchor rope does. Now the anchor can back right out because your now pulling from the elbow NOT the end of the shaft. If you hook it from the end of the shaft and not the elbow and have no messenger tied to the elbow the anchor stays where she lays forever. (Zip ties have been tried, they are just not as strong as halibut cord and break more easily.)
Note: If you do not have a plow/Bruce type anchor, chances are you have a "lunch" anchor (nice for a lunch time break during the day, but not for sleeping at night in the dark...) Only the plows head for China the more they are pulled on. Yes, others may work, but while your boat whips like a kite tail in the wind in the dark, if you don't have a plow type she can drag. When the water stops lapping at the hull and your boat stops whipping side to side, wake up you are dragging anchor!
I break my cord maybe a couple times a season, the anchor works the same with or without the cord attached to the chain. I have slept through storms that whipped the boat side to side in sharp jerks for hours, that broke the cord, but didn't affect the hold of the anchor. (ALWAYS, SET YOUR SHALLOW ALARM AND DEEP ALARM ON YOUR SOUNDER! IT'S ONE THING TO WAKE UP ON THE ROCKS, ANOTHER IN THE MIDDLE OF THE OCEAN!)
I hope this cleared up some stuff, I know pictures would have helped.
