I remember long ago, when I re-rigged by Cal 20 it had sheaves
specifically for wire. I switched to spectra and switched the sheaves to
Delrin, which I took to be the standard. I recall there are also aluminim
sheaves that accept both line and wire. Delrins are injection molded, so
I'd think that there might be some inconsistencies in them from time to
time. I believe the GFN sheaves are also injection molded but stronger.
Looks like there are also Delrin GFNs... :-)

Both my CT-41 (first boat) and my Rawson 30 (current boat) had wire crab
winches for the main and jib halyards when I bought them. The first thing
I did was to replace those wrist-breakers and get rid of all those fish
hooks. Now with the ultra-low-stretch super-strong lines being available
in small diameter, I have to wonder whether wire tails couldn't be
replaced with the new technology. No fish hooks, anyway. But I still loath
crab winches.



I was fortunate that the previous owner of the Sabre dealt with those sorts
of issues. How did you like the CT? I had a very pleasant trip on a slightly
larger version (48) some years ago. Didn't much like the hydraulic steering,
but other than that, it was a nice boat.
