Since the listing doesn't say what it's made of, or what it's characteristics are, I wouldn't buy it. I want to know things like stretch, abrasion resistance, UV degradation and such.
Go to a boating supply store. They've got a good choice of ropes to pick from.
I've a 1,000' spool of 3/8" braided dacron rope myself. Cost me something like $60. Very usefull. I do keep a number of whipped 50' lengths around for whatever purposes. That is a handy and usefull length.
