I like three strand rope for docklines. It has nice stretch.
I sold Samson rope for about fifty years. Great rope.
In three strand you want a pre stretched or heat set rope. Only high end manufactures like Samson and New England do that. It will feel harder than non treated rope but it resists abrasion much better than soft ropes.

I brought in a line of Chinese rope because people want cheap crap. It really was crap but it sold.

The Chinese 1/2" rope had a breaking strength of 4200 pounds. The Samson 1/2" had a breaking strength of 6300 pounds.

I made docklines specifically for my home dock and left them there when I went out.

I had six docklines that I carried with me. They were each the length of the boat and had a 6 foot circumference eye spliced in one end. Since they were all the same length, I could just grab one and know it was long enough. The 6 foot circumference eye was big enough to drop over a piling. Having six gave me two bow lines, two stern lines and two spring lines. That's what worked for me.

I have no eye splices but use bowlines for the pier cleat, thereby the eye is the right size for each attachment. About 8000lb breaking strength 1800lb Working. Soft, easy on the hands and NO memory.

Those are my traveling lines. I use cheaper 3 stran at home slip.
Correction...1/2 inch 8 plat (brait)

Hmmmm. Maybe it's an orientation issue.

There appears to be the toe of a shoe at the bottom left of the picture I see.

Would you agree that the 3 strand is 45' and the braided is 30' ?

I have bought all my dock lines from Miami Cordage. No complains at all.
They are a bit over size for my 34AT but during the hurricane I was happy to have them.
I have 2 bow lines 4 stern lines, 4 spring lines, fore and aft, plus another set for spares and during high winds or hurricanes.
If one has to double up all lines, it does help to have a second set. Makes the insurance company happy.
Personally, I like double braided lines with stout bowline knots.

Dan, with all those lines, I'd be more concerned with the reliability of the docks' cleats and the docks themselves.

Me too plus I am concerned about the reliability of the boat cleats too.
I want to be able to prove to my insurance company, I did my best.

That picture was taken with my phone, when I copied it from my computer pictures it appeared as was as posted. When I clicked "preview post" it appeared flipped, so I corrected in preview, when it I clicked "post" it flipped back again so doesn't match the text.
In any case, the text is correct: "A black ring for each 10 feet a red band for 5 more feet. I round off to 5'."
Reminds me of backwards slides in a 35mm carousel!

Dan, The folks at Miami Cordage are really nice to deal with. They now make a heat set 3-strand nylon that is comparable to New England and Samson. It's much more abrasion resistant than their untreated nylon.

I wonder what boaters in China use?

I find that cheap lines unravel and just don't perform as well as quality USA made lines.

When I bought my first set for my N46, the old man insisted I tour the place where they 'made' the lines. It was VERY interesting.

From what I have seen, they use all Chinese products - Chinese engines, ropes, steel, windows, glass, electronics, etc.

I wonder what American products the Chinese import?

Article in today’s paper. Ford Mustang sales up 33% in China this year. Base price for a Mustang in US is around $29,000. Base price in China with tariffs and tax is $69,000 or so. Looks like we negotiated a bad deal.

I have no doubt that China produces good quality rope products, but 99% of the orders to China are for cheap bargain priced goods. They currently produce some of the best electronic goods, satellite systems, computer goods etc etc. I see no reason why they wouldn't produce top quality rope if someone wants to pay for it.

Regarding dock lines in general, why is stretch required? In my case, I use short dock lines (all between 3 - 8 feet) which would have little stretch, and I keep them fairly tight on my floating dock. I have a thing about not having any lines attached to the boat which will reach the prop. There wouldn't be more than 6" movement in any direction even in a strong gust, so there is no chance to for the boat to build up any momentum.

Others are recommending much longer lines with more stretch. I understand that would be required on a non-floating dock, but why use long stretchy dock lines on a floating dock?

We all make fun of Chinese goods at Walmart and Harbor Freight, but remember that the Chinese do send people into space, that America relies on THEIR space program to support our operations as well. The challenge is trying to find the truly high quality products - and if it is worth the effort to you. For the average guy living in America with all of its resources, the answer is probably "no."

That's the way I learned it also - you want little or no stretch in a dock line. In surge or heavy pulsating winds (turbulence) you can create pounding of the vessel against the dock or mooring ball.

Stretch is more for fixed docks....and arguably for storm conditions anyplace.

“Others are recommending much longer lines with more stretch. I understand that would be required on a non-floating dock, but why use long stretchy dock lines on a floating dock?”

The longer the line / the more angle / the more stretch/ the less stress is put on the boat and dock cleats. We had a storm a month or so ago and people at the marina had short brest lines. The lines were tied from the midship cleats pretty much perpendicularly to the dock. The boats got rolling and pulled the cleats right out of the dock. The boats broke loose.
