You may wish to clarify what parts
of the rig exactly you're looking to replace. Along with how much, if any of it is DIY
vs. the rigging
shop doing it. Also, who's providing the materials, as that can make a huge difference. And are you talking mechanical terminals, swages... or perhaps going to Synthetic Rigging?
It's worth running several sets of numbers, for the different methods of doing the job/having it done, as well as comparing materials & suppliers.
Also, if you're re-rigging, now's a good time to inspect all of your tangs, bolts, spreader ends, turnbuckles, electrical wiring
, etc. Adding a spare run of electrical
wire while the spar's down for anything you may wish to add 6 months from now. Ditto on adding an attachment, & perhaps sheave box, for a future spare halyard
. And or a tang/nose/beak for a Solent Stay, even if you don't add the stay now.
I always think it though as if I won't have the rig down for another decade, & given that, what would I then replace, & or add. All the way down to the type & size of bolt or rivet used for X. OCD, maybe, but it helps with peace of mind in terms of having a solid rig. And the fact that I measure, photograph, & record
the sizes & part #s of literally everything, surely does help when it's time to fix X that's 15m off of the deck
. That or when you go to sell her... the new owners surely will appreciate it.
