|boatpoker||Whether it fails at the terminal or the rod itself is immaterial. A failure is a failure. Dye testing will not show all the flaws and even an experienced rigger more often than not cannot tell when a failure is likely. If a boat has been stored with the mast up here in the Toronto area and raced every Wednesday night for the last 25yrs. I sure wouln't take it offshore and salt water just increases the risk. While it is immensely strong it gives almost no pre-indication of spectacular failure. Common sense will tell you that nothing lasts for ever and several million cyclic loads cannot help but hasten the end of rod rigging.|

i think rod is a matter of trust. almost all rod is discontinuous. this makes it interdependant on itself. mast column failures are the result of failure of any one part. continuous rod would be safer imho, for cruising. however, i rather view it like crossing an avalache prone slope in the mountains, a less than one percent chance starts to be pretty uncomfortable after many exposures.
for rerigging rod to wire, this is essentially a re-engineering project and well as the rigging work. there are some good books on this, i would start with the rigger's apprentice as being the most accessable.

I am thinking that there may be some issues with UV degradation over the long term. Although I am under the impression that there is a shielding layer on it, chafe and wear could possibly erode the shielding, leaving the cable exposed to sunlight, in places that were not noticeable from the deck...
I'm going to wait for a few more years to see how it wears...

I had a 77 Heritage West Indies with rod rigging. I had mine rebuilt by a rigger that cut the ends off and reformed them. This is what Navtec recommended and it cost me about 2k. The rigger said it was good for another 20 years. Call Kevin at stixnrign in Kemah Texas.

I know cruisers who've retired otherwise sound rod rigging for wire just because it's much easier for the voyager to maintain or replace themselves. That's not so much a knock against rod rigging as it is a comment on the "self-service" systems (Hi-Mod, Sta-Lok) available for wire, that readily available, easily stowed and handled "form factor".
Of course, I suppose the absolute winning way to go would be to carry a few pre-cut fibre stays if a rod fails, but what if it fails during a bad blow?

Catastrophic failure of rod rigging is well documented. I know of at least three boats that have had it fail with no warning. Also, when you're out cruising, it is important to have rigging that is easy to repair, as in many areas, rod rigging and the tools needed to make it are not available. Rod rigging can also be damaged more easily, by impact to the rigging than wire rigging, which is more flexible.
The real weak point of rod rigging is the terminal ends... but that is also the case on wire rigging. Wire rigging rarely fails in the middle of a cable... it usually fails at a terminal fitting. However, wire rigging usually gives fairly clear warning prior to failing—meathooks, rusting, etc—rod rigging has no such warning signs.
Fiber rigging, like Spectra, Carbon Fiber and PBO is interesting, but not really ready for prime-time usage yet. It is very expensive and relatively short-lived and much more fragile in many ways. It is used on racing boats, but these are boats that are inspected very regularly and have budgeted a fair amount for replacing the standing rigging on a regular basis—which is generally not the case with a cruising boat.

My 70's Heritage One Ton had rod rigging. It had been replaced in the mid 80's, so it was about 20 years old. The P.O. caught a gust from starboard, heard a gunshot, and the whole rig came down in a spectacular crash with the mast breaking off at the gooseneck and falling over to port. Fortunately, no one was hurt. Basically, the P.O.'s wife told him he was all done, and I ended up with the boat.
Turned out that the headed end on a D1 had parted and a turnbuckle had parted - both to windward when the event happened. There's no way to really determine which failed first. We were able to salvage the mast and boom. The furler, hydraulic vang, hydraulic backstay adjuster, jib, main, port lifeline stantions, and most of the running rigging were history.
With some input from Charley Morgan (who built the boat), we were able to splice the mast and get her re-rigged. Getting the rig back up (sans sails, etc) using wire cost somewhere in the neighborhood of $16K. The estimate to re-rig with Navtec rod was about $25K. We went with wire due to cost, servicability, and "piece of mind factor".

I have no connection with this company but they rate all types of rigging.
It is a bit of an eye opener when some people are talking about riggs 20+ years old. What will the insurance company use when it comes to a claim.
