Re: Not Getting the All-Chain Thing
I think the attached picture says it all when deciding whether to use chain or rope! The picture is of a rusty 200#plus anchor fouled our chain about half way from the anchor to the bow. Just how long would a bit of rope have held up?
If one is day to day anchoring on rocky or coral bottoms without chain, it is almost a certainty that the rope will wrap around something or rub on the bottom and chafe through, sooner or later. Chain just won't do that. I've even seen line chafe through on a perfectly clean seeming sandy (or mud) bottom, because there was something (a steel I beam, a bit of an old wreck, an anchor, etc) down there, unknown to the anchorer.
For my taste, on any boat under 60', I think 200 feet is sufficient quantity of chain to carry. Most of us do not have a windlass strong enough to pull chain up from much deeper, and I would hesitate to anchor a small craft in water over 75' for any length of time anyway. With our Rocna, we've found she'll hold pretty darn well at 2:1 in a good bottom, by the way.
As discussed in so many threads, a snub line is a great addition to all chain, but it is mostly to silence the chain and give some elasticity to an all metal system, until things get really hairy. Then the snub is what keeps the chain from breaking, once it is tight from the bow to the anchor. None of us can afford to carry chain strong enough to actually hold the weight of our boats, so the catenary and snub make the BBB chain just as strong as the expensive HT chains.
