I made up so specific length dock lines and was pretty careful to get the lengths right.

I then took the shortest of the lines which is about 24" eye to eye and I wet the line and then put a length of pipe thru one eye and hooked the other over the garage door handle. I wanted to see how it might react to the load, expecting it to stretch, maybe...

After a couple hours of this load I didn't notice any stretch, so I took the pipe out and set the line aside.

Today the line has pretty much dried out and now is about 1-1/2" to 2" shorter than the original template line, which is not what I need it to be for the specific pole and cleat I will use it on.

The line is 3- strand 1/2" nylon by Wellington, which I expect to be fairly good quality stuff.

Nylon line shrinks? Guess it does because I see it. Maybe it takes a set after wet/dry loaded an unloaded cycles?
