Ok, I've found out a lot more in the last 3 weeks, but am frustratingly no closer to making a decision. All I've learned is that Navtec parts are really expensive and complex. And that everyone I talk to disagrees with the previous person (ie, even professional riggers don't agree on what is recommended + safe) - I suppose this is normal in sailing though.
I found a few more old threads from the C&C list: http://cnc-list.com/pipermail/cnc-list_cnc-list.com/2011-November/041498.html http://cnc-list.com/pipermail/cnc-list_cnc-list.com/2014-April/066294.html A lot of it seems to come down to the Navtangs. Navtec changed the design several times (to make improvements), and Navtec had so much employee turnover that there's only one guy remaining who has been through all the iterations. My previous thinking was based on that my '84 has K150 tangs with SS tie rods (confirmed by a rigger when we pulled one tang last year). And the tang was easily unscrewed, which lends me hope the other 3 would also be similar. So I assumed I could reuse my tangs, because it seems other C&C owners did so, and last year's rigger said it looked reusable (based on visual inspection). However a more conservative rigger basically implied I would be stupid to reuse it. Navtec recommends replacing them - but Navtec recommends replacing anything older than 12 years old, so I don't really know what to make of Navtec's advice (they have no incentive *not* to recommend replacing their hardware with new hardware of their own). A local rigger told me the navtangs are $1000 each. I have 4 of them, so replacing them would basically double the cost of a rerig (and that's not counting any labor cost). (I think the $1k/each is an overestimate though - I found a price online of $500-600). It seems like a lot of people who have rerigged haven't actually done full rerigs - ie, they reused turnbuckles, or tangs. I do agree with the more conservative rigger that it doesn't make sense to leave a "weak link" in the system. But I'm not sure whether old navtangs must be automatically condemned into the category of being a weak link. I'm seriously thinking about a wire conversion again, but that has it's own complications. Has anyone done that on the side shrouds? From archives I know Calypso did forestay/backstay, but those are easy to convert. The mast tangs and discontinuous lower spreader junction are the tricky part. I found a Youtube channel where they replaced their Navtec rig with wire: https://www.youtube.com/watch?v=FVhj714rleQ But they have a Niagara 35 with a single spreader rig rather than double, so that makes it a bit simpler. And the well-known rigger Brion Toss has said (in his forum) that for a C&C, he would stay with rod, because rod makes a difference to the responsiveness of C&C's. -Patrick 1984 C&C Landfall 38 Seattle, WA On Thu, Nov 3, 2016 at 9:16 AM, Patrick Davin <[email protected]> wrote: > Right, I totally get the mast would need to be pulled if I were reheading. > Doing it one side at a time would take too long.
