There's nowhere to run here and I'm already pretty much in the middle. I've tried that snorkeling face mask thing in past and it was little help.
The event wouldn't have bothered me as much I think if I had a 7:1 plus scope out, but the 4-5:1 I have is different. On the other hand I've been here over a week and there has already been lots of 20 knot wind days and my anchor has never drug in 2.5 years once it was fully set.
Something very interesting has happened since I got the 88# Rocna and the ˝" chain.
When I was using the genuine CQR (or Rocna) and 3/8ths" chain I always put out as much chain as I could, stating that the chain did me no good in the locker. But with this rig I rarely use more than 3:1 plus the snub, and the boat stays put better and sits much better on the anchor (less swinging and sailing).
Obviously, should a big squall blow through, I could put out a lot more chain, but as yet I haven't had to, even in winds over 60.
I was taught 3:1 for all chain and 5:1 for chain and line, and at one point I had 125' of chain out in 15 feet of water for Christmas Winds in the Tobago Cays, which left others a lot less room to anchor around me. When asked, I still say I've 30 meters or more, just so we have a bit of room between us and the bareboats.
So, we rarely have more than 50' of gear out now, trying to anchor in 15' of water as often as possible. This is also adding to the longevity of our chain, as we aren't dragging it across the bottom so much.
I know anchoring is a very personal thing, but I believe with a properly matched anchor tackle setup, one doesn't need to put out a whole bunch of extra gear. Using an extra heavy anchor with lighter, stronger chain is completely a false sense of security, making the chain the weak link in the system. None of us can carry chain that is actually strong enough to hold the boat, once the chain is stretched tight from the anchor to the bow, so a weaker, heavier chain may be better (and cheaper), just by virtue of the catenary effect being the difference in shock factor.
The new gen anchors can definitely create new gen thinking about anchoring, though really, I was taught the above formula in the '60s.
