If you are doing your own work then perhaps it is more economical, but if you are paying others the it is doubtful The first problem comes when you attempt to locate proper heavy duty thimbles for the eyes. Damned hard to find. Next comes splicing the eyes in the cables. Again, if you can do it yourself and have the tools then go for it but if you are paying rigger's rates then get your wallet ready. Now you have the cables cut, spliced around proper heavy duty thimbles. Next step is to worm, parcel and serve all splices and usually the lower cables up 10 - 15 feet above the deck. Once that is done you need to mix up some slushing and paint the cables, working it well into the wrappings. Now! At last, you can rig the boat. But remember that annually you will need to inspect, replace worn wrappings and re-slush all the cables and slushing is a mixture of tar, oil, Japan dryer and various other arcane substances. (think roofing tar) so don't even begin to think about slushing down the rigging while in a marina slip as you will sprinkle not only your deck but your neighbor's decks with sticky, black, tarry gunk. Now, having said all that you might be interested that properly maintained galvanized rigging will out last stainless. Cheers, Bruce Bruce where the hell do you get that idea? spend a couple pennies more and get the better galv. you just described what i do to my standing rigging and mine is all manella and hemp. yes with proper care galv will out last SS but the level of care is not serving the bloody thing. you soak the cable warm for a bit till the grave penetrates the core and then gravy the outside about twice a year. If you want galvanize to last 15 - 20 - 30 years, or longer, then you do it the old fashioned way I described. Otherwise you will be changing the stuff every ten years or so. Hell, I've seen boats rigged with telephone pole cables and cable clips. It works but you get to replace the rigging pretty often. If your standing rigging is all hemp and manila how are you making the terminations? Spliced eyes or served? Cheers, Bruce |

He made a rope ladder, all rope, no wood steps, and not anchored at the bottom. Only a kid trying to get to the tree platform would put up with it. To digress, the mountain climbers have short rope ladders with four inch aluminum steps. Why not a long one and haul it up with a halyard. I guess a bosuns chair is far better, unless you are alone. I believe ladder steps are far cheaper than mast steps. Not marine. I am a coward, and don't want to climb ladders without a harness clipped to a halyard, with someone tending the other end. Casady |

Cheers, Bruce depends on where it is. on most they go to the upper dead eye and eye spliced the wormed puddinged out parceled and served then a leather is sewn in and well oiled. the lower dead eyes are strapped and the lanyard is wormed parceled and served as well. each bolt that has a line to it has a thimble and a spliced eye treated the same . this is how my cargo boom mast and stops are set up |

How much per shroud/stay for a rigger to do all this splicing - serving - parceling -etc plus the annual inspection and re-slushing? As apposed to cutting a length of stainless and either swedging a terminal on the ends, or screwing on a sta-lock fitting. Inspection is a yearly look at the terminals with a magnifying glass. Just as the old cotton sails, the initial motivation is to decrease maintenance. Cheers, Bruce |

I understand the Maintainer time issue, I dont tend to agree with it but i do understand. However i have yet to see anyone running Galve that spends much time on the rigging. certs not more than a day a year. IMO folks should take a day a year and run through the rigging in any case. Ahh well I'll keep mine no matter its quiet and easy to work. I am a lazy old troll. |
