I moved my 4 main dock lines from 3/4" to 1" last year and I like the heavier lines much better. I was fortunate to have a close friend wanting to get some 1" out of his garage so I happily helped him dispose of it

. I cut and tied bowline's for a loop end with the fire hose protecting the loop. I made the loops large enough to slide over the dock pylons.I used old fire hose as my chaffe gear on the lines.On paper the 1" seems like overkill.... but in my hands, and to my eyes it seems about right. These boats are heavy and catch a TON of wind. Florida thunderstorms can be flat out nasty with super heavy winds.Now, if I were transient, or cruising, I would have a set of braided 3/4" lines to use for daily docking duties. But for staying long-term in a slip 1" three strand would be my choice.
