Boris and Tom-
I don't have any problem with the traditional way of splicing three strand, and it's probably stronger than the other one I figured out. We'll never know without testing, for sure. It's just that the traditional way makes for a big transition in diameter from the chain to the doubled back rope, and hangs up on some brands of windlasses.
The rope chain suggested in the ebay auction above has at least two problems:
1. The rope is not spliced properly, and the big thimble will have to be removed and the rope spliced to the chain to pass through the windlass.
2. The chain is the wrong type. Those long links are not High Test GS-40, and won't fit in the chain pockets of the gypsy, and, in addition, the chain is made from 5/16" extruded wire, welded into links, not 1/4".
Moreover, the brand, and therefore the stiffness and suitability of the 1/2" rope are not defined, so it's probably non-domestic, and probably of Chinese or similar origin. Looking at the other things the fellow's store sells, helps confirm this. Not that all foreign stuff is bad, but sometimes/oftentimes the quality is off, sometimes by a lot, and there's a good chance it won't work in your windlass, and you may have a hard time returning it once it's been tried out and is "used".
Boris and I are really on the same wavelength here. Get the good stuff, however you get it, and do it right the first time.
You wouldn't skimp on a fishing rod, reel, line, terminal tackle, or lures, so why cut back on the stuff that holds your $$$$$ boat to the bottom? (Sorry for the overstatement!)
Hope ya'll are havin' a g'day up there in the PNW!
