I'd trust a manta over a danforth
or its ilk any day of the week. At least here in puget sound, I have seen/had more issues with danforths
dragging than a plow style like my bruce, fast set or equal. That is not to say someone should not have a danforth
at there disposal if in clay/mud! That is probably the best anchor
option for that soil material.....
Nor am I going to carry 150M/165' of chain for the area I sail in. That would be WAY too much wt to carry when racing, even tho my bruce setup is down below. No way am I singularly, or with a crew going to pull that much chain etc up. Most around here use a chain/line rode
combo. Then again, we have very few if any spots with corral or equal rocky/jagged type area's that one might cut thru rope of proper size. We do get the wind, but not the waves or exposure. If it is going to be that bad....there is a marina I can tie up to usually with in an hour or two of knowing said forecast is coming thru.
Not if I was sailing to Oz or some such thing............now I would have a different setup, probably with a bit more chain, or a longer chunk for those really windy days etc. I've held with no issues into the low 30 knot range with what I have. But again, most of puget sound is sandy god holding overall.....with a few exception as all places have.
