Taking a look at Yale's 'white paper' on Anchoring Technology, it is an unabashed advert for their 8-strand nylon anchor rope.
Would have liked more on abrasion, stretch, UV endurance, elongation under load and melting. Why it's better than the other guy's.
Tests, charts, something.
3 strand and 8 strand have the same breaking load spec. But it takes 8 strand 75% longer to get there, something like that.* But 8 strand has all those other things going for it.
On forums, the guys who actually have the stuff love it. The rest are opinionators, who don't know the difference between braided, plaited and hard laid.

Guess that 8 strand nylon is NOT a 'high modulous' line. Too stretchy.
Don't know if those urethane coatings Yale has are appropriate for 8 strand nylon anchor line.
Wouldn't it be nice to paint or dip on extra abrasion resistance and UV protection?
Don't you get the feeling that most of our cleats and chocks are left over from the age of manila rope?

Can't trust a bowline in plastic rope. You hear of splices sliding apart under load. Can't hardly squeeze the stuff in a cam cleat - sometimes it breaks where it turns on a sheave. And it can get hot and melt for crying out loud!


google> Cruising World - Getting a Line on Cordage

is a brief intro into the high modulous plastic ropes.
Has nothing to do with our anchoring inquiry here, but plain ole rope sure is getting complicated.

*It's a dark and stormy night - I'm at the bow pulpit, hanging on with hands, arms, knees and feet - checking out the 8-strand's chafing gear. in a modest 45mph blow:

"....That's 25%.....no, that's more like 30%.......
wow!...wasn't so bad... maybe only 10%......
O H MAN.... that was huge... had to be 45%!!!!"
