When I replaced the ground tackle on our project boat I did not hesitate to relegate the 15 feet of half-inch three-strand nylon rode to the bottom of the cockpit locker. During the years I spent sailing around Europe, I became a firm fan of plaited nylon anchor rode. It piles up tightly in the anchor locker and pays out neatly, without kinking or twisting, and I believe its shock-absorption qualities are superior to those of three-strand.
When the time came to upgrade our anchoring system, I was tempted by New England Ropess Megabraid, a 12-strand rope that is very good for docklines, but in the end I was seduced by a great deal on a length of Yale Cordages Brait, a comparatively recent arrival on the anchoring scene. It has the same soft hand as the octoplait I used in Europe and the same resistance to hockling, that annoying tendency of three-strand to form loops when its twisted. I bought 20 feet of 5/8″ Brait to splice to 70 feet of 5/16″ G4 chain, which I hooked up to my Delta anchor. I figure this should let me sleep well at night in anything short of a full galeand if Im anchored in a full gale, theres no way Im going to go to sleep anyway.
Yale has some well-laid-out instructions on its website for a rope-to-chain splice, which you will need to follow if you use an anchor windlass. However, since I dont have a windlass, I replicated the long splice Ive seen used numerous times on boats in Europe. You can find these instructions on the Jimmy Green Marine website. I doubt theres any breaking-strength advantage, but it just feels better to me to have the rope woven through a number of links of chain than just doubled around one link. At any rate, I have to say that you follow these instructions at your own risk.
