And after you've plowed through all the stuff Hud pointed you to, here's the jist of it for quick reference:
1. New generation anchors -- Manson, Rocna
, Spade -- are regarded by practically everyone who has tried them as vastly better than anything else as a general purpose bower anchor
. Well worth switching to one of these if you've got an older type of anchor.
2. No one has been able to prove that any one of those three is any better than any of the others, and many of us think that there isn't any real difference other than hot air.
3. Size matters. Get the biggest anchor which is practical in terms of fit on your bow, handling, etc.
makes a great kedge anchor.
All you need to know about anchors. Now you want to know about chain versus rope
, shackles, anchoring
