Let's not all make the same mistakes. If something does not work, let's share that so others can be spared the disappointment. We had a rigging wire disappointment:
The Tiki 46 plans came with a recommendation to use plastic impregnated galvanized wire (a Norseman product) for shrouds and as strops for the halyard blocks. We learned that Jeckells would make these up for us professionally in England and we were led to believe they would last around 20 years. In use, they have lasted 7 years and over 30,000 miles but now we are finding cracks in the plastic which let in salt water with corrosion of the wire as the disappointing result. Last month the strop holding our main sail peak halyard came adrift and fell to the deck. So our main sail was not used from Charleston, SC all the way to our summer mooring here in RI. A close look at the failed strop showed us that the plastic cracks were not the only problem. Water also got in past the swedge shrink sleeves causing wire breakage and there was chafe damage where the plastic in the loops wore away against the mast and revealed galvi wire to the elements. Needless to say, we have lost confidence in the product which was professionally made up to the design specs by the company recommended in the plans.
We do not fault Wharrams in this because they have the product on their own boat, but others with the same product on their boats might want to make a close inspection since loss of shrouds and strops at sea can be dangerous. This wire was designed, as we believe, for use commercially on large radio and tv antennas inland. Boats, especially flexible boats in salt water environments, are another situation entirely. We liked the smoothe plastic coating while it lasted because it was kind to the sails and our hands, but it is apparently not up to the job on our boat. This is simply our own opinion arrived at in use of the product and we have not contacted a trained surveyor.
Next week we will head to Maine where we plan to haul for painting, remove both masts for painting, and replace all wire rigging made with this Norseman made plastic impregnated galvinated wire. We may use plain olde fashioned stainless steel wire to replace it, but have had other suggestions of using some of the new fabric material on the market. At this point we are reluctant to use any material that is "new". In fact "new" is starting to look like a four letter word. Ann and Nev
