Seems like a lot of trouble to have your lines shackled to the dock, if you wanted to take them with you on the boat. Do you put a wire or zip tie through the shackle pin to keep them from unscrewing open?
Do lines have a problem chafing through where they are tied to a dock cleat? My lines seem to get far more wear where they rub something on the boat.

To clarify what I'm going on aboot, I use the terms in this way;
I use the term "docking lines" for lines that I use in the process of docking as well as while temporarily attaching myself to a dock. I mean, they are not permanently fixed to the dock.
I use the term "mooring lines" for lines that are permanently attached to where I moor. Although we often think of this as a mooring ball, it is not limited to such. No translation required, "mooring" has the same meaning in the simplified, American English version of the dictionary. (g). In my case, the mooring will be floating docks at the club
A typical practice, and often requirement, at yacht clubs is to permanently attach chain to the docks (or cleats) and then the lines are permanently attached to the chain via a thimble spliced into the mooring line. This provides a strong attachment point with good chafe protection... good for safety, good for club insurance. :-)
I boil it down to mooring lines stay on the dock, docking lines are kept aboard the boat.

I'm confused here. You're mooring against a dock?
Are you docking alongside a dock? Or moored to a ball? Or docking bow/stern in, med style?
I've never heard of thimbles being used or needed in a docking line, which is normally cleated off in the US. (I'm probably losing something in the translation, I'm not really fluent in Canadian. (G) )
The purpose of 3-strand docking lines is that they have some natural spring in them, as you pull tight they untwist a bit, acting as a torsion spring for their entire length. A braided line can't and won't do that, making it unsuitable for docking or mooring lines as it will chafe instead of stretching. Sure, they feel smoother and can be used--but they're the wrong line for the job. Wornout halyards, etc. are often the source of braided "docking" lines, just being used a bit longer before they get scrapped.

Don't use that page as a splicing guide. That splice is completely wrong. The strength of an eye splice comes from the bury of the line inside itself. Not from poking the core though the core a bunch of times. All he did was make a huge stress riser where the diameter of the line suddenly shrunk were the splice ended, and sure enough that's where his splice broke.
It's like tying a dozen overhand knots instead of bowline. An overhand knot is weaker than a bowline. A dozen overhand knots doesn't get any stronger, but it does get stupider.
A proper double braid splice can be seen here: YouTube - splicing double braid
Or in these instructions. http://www.samsonrope.com/site_files...Splice_Rev.pdf

Ok, I have my answers. Now to go looking for good deals...
Peter, great! I like working with rope and will add braid splicing to my repertoire soon. I've bookmarked that link, it's a good one. Thanks!
