Another thing to consider - the angle of the shank at various scope ratios.
You might want to look at the following site: http://www.pbase.com/mainecruising/anchor_scope&page=1, and be sure to look at page 2 as well. Once you get beyond 6:1 the return on longer line or chain drops off pretty dramatically. It is near logarithmic in my estimation. The weight of the anchor chain helps the scope up until it is stretched tight. After that, the gain from the chain is lost. I.m guessing that will happen at around 40 or 50 knots of wind when you really want it anyway. t's just weight, and it doesn't stretch, meaning lots of shock loads on your cleats and gear. So, yes, put out more chain if that makes you feel better, but don't lose track of the fact that if your anchor is properly sized, digs in reasonably well (as should a Delta, Plow, Rocna, etc.) and has decent holding, even one boat length of chain on a good anchor should easily hold in a 40 - 50 knot sustained blow. To reduce the chances of grief, anchor in a protected cove. Finally set an anchor drag alarm like the Drag Queen anchor alarm app. Just my $.02 worth, Bruce Whitmore (847) 404-5092 (mobile) bwhitm...@sbcglobal.net
