Re: Replacing wire runing rigging with Dyneema
|
Cyric Halyards that small will be hard to handle, will not fit a clutch or winch, and will be very slippery as well. Better choice is a braid with a vectran or dyneema core of 5/16 or 3/8 diameter.?

Cyric,
I don¡¯t know what size DyNema I used, my rigger friend did not have to remove the jacket. Runs like butter with the original equipment!
The shives are close together, When hoisting the man I have to keep the thumb tab on the locking pin opposite the other shive line.
I installed a PVC conduit which holds all the wiring and keeps things from slapping,
Good luck

Hay all.
Since i got my mast cap off and can inspect everything. i thought i might replace the runing rigging wire halyards with Dyneema or other quality synthetic line. To do away with the old wire, one has already been replaced by standard size line, but it does not run very freely and i see it wearing excessively due to its larger size in the smaller sheave. so i thought i might replace it with 1/8 Dyneema (tartan book says wire is 1/8?) would be easier. what is everyone's thought on this? i did a search, but only came up with Dyneema for centerboard use.so thought i should ask specifically.
Thank you all for your time and attention

Hello Mr. Elmquist
Thanks for the info.
i have thankfully have the .pdf of the Tartan Handbook. it lists the wire part of the halyard as 1/8in.? the breaking and working strengths of 7x19 316 stainless cable is?1,670 lbs and?335 lbs give or take according?to the info i have found.
I found this on west marine, the 1/8in has a breaking strength of 1200 ibs, which doesn't measure up, but the 5/32 which is 1mm bigger has a strength of 1900 ibs. i don't think the extra MM of size should interfere with things much?? im just trying to figure this all out i guess.
