[C320-list] Rig Tune

[John Dean]

Thanks for the info. I replaced my standing rigging last year doing most of
the work myself
and the total cost for materials & labor was about $3000. I had our local
boatyard pull the mast with their crane and lay it down on the boat then I
motored over to my Yacht Club and used our clubs crane to lift the mast
horizontally off the boat and place it on saw horses in the yard at the
club where I removed the spreaders, shrouds and masthead sheeves which I
replaced. I also replaced the anchor light with a new LED model and
replaced the roller furler with a Tuff Luff since I actually do more racing
than cruising and wanted the increased performance of having a longer luff
on my 155% racing genoa without the roller bearings in the way plus getting
the extra weight of the roller system off the bow. I had a local rigging
shop make up the new shrouds & stays making allowance on the forestay
length for the absence of the rollerfurler (and some additional rake) and
replaced all the turnbuckles. The stainless pins that secure the spreaders
to the mast were hard to get out (and pretty beat up) so I replaced them
with new ones obtained from Charleston and got the new sheeves from
Catalina Direct. I rough tuned the rig when I stepped the mast and have
been sailing it that way for about six months but now that I have the clubs
Loose Gauges I'm fine tuning it but will be using modified settings from
the Yeager article tension numbers since I often sail slightly overpowered
in some pretty rough conditions off the California coast I don't feel
comfortable having the leeward shrouds flapping in the breeze as the Yeager
settings allow. I'll post the final readings when I finish tweaking it.
