Although it would probably be good for natural fiber lines, I think it might

each other and the friction gets them hot enough to melt and break. That's why
lengths of old garden hose are also a bad idea. Nylon requires water.

For everyday chafe protection in mild conditions this wouldn't be as much of a
problem. When things get rough, however, it's a very different story.


Have you ever personally seen a nylon line used for berthing or mooring
actually get hot enough by this mechanism to melt or break?

Well, the OP was referring to a storm anchor, so I would think it to be
relevannt. For out-of-the -ordinary circumstances, I would accept lab
results.

That's just what I was going to say.

I have not seen lines that broke due to this, but I have
replaced lines that seemed to have little needle-like
hardened strands in them. That Boat US article was a very
good explanation and seemed very plausible to me (after
having seen partly melted strands in rope).
