Diameter Dock Lines?

[RickieT]

Had a question...I have a 350 Mariner and need to replace my transient dock lines for bow & stern...so 4 are needed. General consensus for length is 25 feet...but I am stuck on what diameter line to go with. Would I be better off with 1/2" or 5/8"? What are the pros and cons?...going with nylon double braided pre-spliced or 3 strand????

Any comments or suggestions please feel free.

Thanks,

Rick

I have a smaller boat a 3007 aft and I use 5/8" lines. I would go with the larger sized lines.

If you go by the charts your boat can take either. Would go with 5/8 double braided nylon if it were me. See here. https://www.anchoring.com/blogs/anchori ... r-and-more

Ditto on Midnightsun's!!

Like Midnight sun mentioned, I use 5/8 25ft for the two bow and 15ft for the two stern lines.
I found longer line for the stern was a pain.

Many Thanks!!! All set now

Ditto on above. Three strand nylon stretches well and is good for dock lines, but chafes easily. You can’t go wrong with 1/2 or 5/8.
