Standing rigging measurements - for cp23?

[hockeyfool]

  I have  a possible affordable arrangement for replacing all SS standing rigging to synthetic,
can anyone please tell me how to find the measurements for all standing rigging stays, and
possible the lifeline lengths ?

Take the old ones off and measure them. Or drop 'em off and
have some boat yard make up a new duplicate set in ' synthetics ' what ever that is.

Is there still turnbuckles involved for adjustments?

Both standing and lifelines? [UV worry with synthetics ?]

skip.

  Ok , thanks -for the ideas,
and the synthetics that I may be soon showing on the upcoming prospective forum, can have either lashings
requiring splices, or can have turnbuckles used with a proprietary terminal.
Testings have been done, and depending on the latitude, specific covers can be purchased to protect
to allow more lifespan.

Just wondering why you wouldn't stick with the 5/32" stainless standing rigging? Mine is original from 1985 and appears just fine. I believe the working strengths for the 5/32" are way overkill for the anticipated loads that one could expect on a CP 23. Interesting, and don't take this personally but if something works, why try to fix it? Still, I'll be following this thread.

Be careful with the synthetic lines (vectran, dyneema, etc).

Problem with these lines is they tend to elongate a bit when tensioned, and will stay elongated.  It's called line creep.  This means you'll NEED turnbuckles to adjust them after the first sail, and probably again after the next few sails.   And you'll need to inspect them OFTEN for chafe, especially where the sheets rub and where they pass through the slot in the spreaders.

I'm not seeing the benefit here.  If we were true racers, then sure we would want less weight and windage aloft and be willing to inspect, adjust, and replace them often for the slight advantage they offer.  But for cruising boats like ours, I would rather have reliability and less concerns about chafe.  But that's me. Your mileage may vary.

When the parks department picks and carries the 10,000 lb dock sections to and from the water we use nylon straps with well designed ends on them for chains to go through when we rig them.

You will NOT 'part' these straps by pulling on them. But one tiny little cut going across the strap will tear these and the load will drop. Any damaged straps are junked. It's just 'cheap insurance'.

I'm just saying that a 'cut' and not stretching, may cause the loss of the shroud [standing rigging]. One way to develop a cut is to use those stupid little ss clips to hold a decorative clip on the 5/32" wire. As the flag flaps these clips saw through the wire. I had to replace one shroud on my CP-19 because the clip sawed through ONE strand of the 5/32" cable. Ruined the whole cable.

To carry this discussion into the absurd when BayShip lifts the 250 ton sections EVERY lift uses cables. Never a strap and never a chain. Straps and chains are dangerous as these devices usually don't give a warning before they fail.

A cable will part the individual strands giving a warning of failure.

Good to know, thanks.  I've never used them and now I won't.  What works well for me is just pulling a HD zip tie cable strap, those that have the loop for a screw, around the wire then use those special split rings that have the bent tail on them through the screw loop and the flag grommet.  The plastic zip tie is sacrificial to the SS wire and to UV.  Have to change them every two years or so, but works well.
