Single handed docking - midship spring line size question

[Brad Young]

I am making a spring line similar to the Nauti Duck Dock-A-Matic. I found the link from this C34ia forum. (thanks) from here (Stu): http://c34.org/bbs/index.php/topic,5445.0.html

What size line should I use for a Catalina 34?


Thanks

Brad : To make a spring line for a C34, I'd use 1/2" line. 

[Brad Young]

Thats good enough for me. 1/2 in it is.

Thanks

Brad,
I use 3 strand nylon and replace it every year or so.  The line isn't that long that it stretches a lot, but I feel that it leads to a softer stop.
Happy landings.
