Has anyone experienced there box anchor coming unset and ending up on its narrow edge with it's flukes pointing horizontal to the bottom? This condition happened a few times to me last summer. I was in calm protected water about waist deep with maybe a 10-15 mph winds, the bottom was sandy and I had my Fortress FX-11 off the bow and my small box off the stern to keep from swinging. It seemed I might have had to much scope out on the box because when the anchor line would go slack then the stern would swing a little and yank the box from it's set to on it's side. It seemed once I shortened up the scope on the box where the anchor line was taunt all the time it didn't come loose. Does more scope on the box anchors actually hurt them? I am wondering if anyone else has experienced this. I have used this box anchor probably a half dozen other times as a primary anchor with out any problems.

Mine slipped a few times when I first got it.You have to set them pretty good.Since I started doing that have not had a problem.Going off the stern it would probably be hard to set it right.
