Good way to not loose an anchor

[meaux fishing]

Well I lost an anchor out in Breton Sound this past weekend so i decided to look at new ones online to see if there was a better option. Well in my search i found a way to rig an anchor so you can un-stick it. here is the link... http://www.thehulltruth.com/boating-...-rig-pics.html

Do yall think this would actually work?

Any other anchor suggestions... will the grapple type anchors hold on a mud/sand bottom?
