With the comments about dragging anchor and anchoring close in a tight area...I wanted to chime in. Around here, we have a plethora of anchoring options...as far as the bottom content; sloppy muck/mud, sandy mud, firm sand, mud and grass, sand and grass and lots of combinations of all of those. While we don't have rocks and coral to deal with, we do have oyster shells and clams that can prevent an anchor hookup in a heart beat. That said...
I am getting ready to do some testing on a fairly new anchor design by an American-made company. I have had the pleasure of using many different types of anchors in my lifetime. This one is different enough that it has got my attention. For "normal" anchoring you can get a hook-up with a 2:1 or 2.5:1 scope...according to the designer.

The manufacturer will be shipping my test anchor in a couple of weeks. I will be providing my results (and my opinion) to this group first as well as the manufacturer name.
All of this was started because of several failed attempts and catching a good hook in a small cove with 20 MPH winds pushing us down on other boats that were already anchored. The bottom was sandy/grassy.
OH...around here...very few people communicate via VHF...even in tight and congested areas. I don't understand this mentality.
