Replacing rod tends to be majorly expensive. Both for the materials, & in that much/most of the
work needs to be done by professionals. Since everything must be measured super precisely, including getting the bends at the spreaders in precisely the correct place, & bent to +/- 1 or 2 degrees. Along with all of the cold heading done with special tooling. Specialized end terminals, & sometimes spreader
hardware, etc. Plus just the rod by itself is expensive.
On some
boats it's not too hard to convert from rod to 1x19 wire, dyeform/compacted strand, or Dux (synthetic rigging). But check first, including listing & tallying all of the needed
parts from chainplates to masthead on all shrouds & stays. And with such conversions it's not uncommon to need different tangs.
As a rough guide for a boat that size, if you're refurbishing/replacing all of the standing rigging, & tuning up the spar in general, plan on $15k. Assuming there are no big surprises. And if there are,
money can start leaving your wallet in increments of $5k
For sails on something like that, definitely get quotes. But before you do, make a standardized list of features that you want for each sail, so that you'll be comparing apples to apples. Since adding features, especially ones which require a lot of hand
work, add cost to the sail quite quickly. Though they're also things that tend to aid a sail's longevity quickly.
That said, for a main, or a RF
jib, figure on $5k - $10k each, depending on cloth/fabric type, & features. And know that for sails of that size, unless you work with a premium, expert
sailmaker, it's really, really tough to get decent
service life out of conventional woven Dacron (polyester) fabrics. As the loads on the cloth tend to be quite high, thus stretching them rapidly, leading to an early demise.
Quite often you're better served by going to
Spectra, or a similar performance
fabric; Technora, Carbon, etc. Laminates basically. Or Hydranet, or a variant of something similar.
Pick up the book
The Sailmaker's Apprentice in order to better get an idea of what goes into sail construction. Especailly regarding handwork, & key details/features. Ditto Brion Toss's
The Rigger's Apprentice so as to better understand what goes into building a rig. At least the basics of such. And with a bit of searching you can find Brian Hancock's book
Maximum Sail Power in PDF online, gratis. It too is worth a read.
PS: There are loads of good tips on the various sail cloths, & cuts of sails here on CF thanks to the good number of sailmakers who are members here.
