Identify type of turnbuckle

[AZ-Oldguy]

I have some unusual turnbuckles on the Endeavor 35 that I will be closing on tomorrow. The Surveyor thought someone might have doubled them up to extend the shrouds or something, but I don't think so, these aren't double, but have two barrels with one center adjusting thread. Do any of you have any thoughts about these?

Those are not odd, just becoming uncommon. I can't remember the manufacturer off the top of my head.

Thanks, Sail monkey, any thoughts on whether one type has advantages over another?

NAVTEC. need a rigger or accesss to roller swager to replace.

IMHO it's a matter of taste

They are Navtec turnbuckles. An inside out design compared to the most common Meriman type. Hope they solved the problem but I had severe cracking issues with these turnbuckles ago sailing in SoPac. Navtec was very good about replacing the turnbuckles but still had issues with the replacements. To be fair to Navtec, this was when they were first introduced in the '70s and probably was a dissimilar metal issue between the threaded center section and the outer barrels.

Personally don't like the design because they are swage only. The more standard turnbuckle with a center barrel and threaded pin outers allow you to use Norsman/StaLok/HiMod ends or swage ends and either a threaded or jaw wire connection.

They're NAVTEC turnbuckles and they are crazy expensive!! Just replacing the upper swage (when you replace the wire) costs more than a complete new conventional turnbuckle!! I have a Ketch rig full of them! they're ALL being replaced with convetional open bodied turnbuckles for the same cost!

Pete,
I have Navtecs presently on my boat. They are ten years old(2005). The turnbuckle is stainless steel and the threaded rod is bronze. I also understand they offer nickel plated on some models and bronze turnbuckles on the larger sizes. The threaded rod can be pinned at the ends for security. They are easy and quick to tune. I have never had any issues with them. Best, Rognvald

Those turnbuckles are most commonly run with rod rigging. The stuff run on racing boats, ergo the price. You can get them & parts for them at the bigger, high end rigging shops. LMK if you need POC's.

Roger that. But if you go & pull up any pics of how rod is setup, you'll see that all of the components in that pic match up exactly, but for the top assembly, swaged onto the wire. And said assembly looks much the same on boats with rod, only that they don't have the extra length above the threads for a swage, but rather there's a cavity into wich the lower cold head on the rod fits into.

I'm to beat right now to dig up any image links at the moment, but I've got no reason to pull your leg.
Though of course, I could be wrong, & this is something entirely different, which yet is compatible (at least visually so it appears) with all of the rest of the bits which you'd use to rig a boat with rod.
Odds are Lewmar/Navtec will have a pic, & if not them, then one of the shops which carries their stuff will have one.

Honestly, it's a goofy setup if you ask me. But sometimes boats get rigged up the way the ones in the pic in this thread are, because thoso someone had those kinds of parts on a shelf in the shop gathering dust, when it came time to put the rig together... and, poof, an over priced, faux gucci cruiser is born.

definitely old navtec

Yes, they are Navtec rods n turnbuckles, have ten of them on my boat. I am not a rigger but I go over them each year and cycle the rods through the turnbuckles with white lithium grease. They are only 39 years new, and the rods are available still.

[George DuBose]

Skylark came with Navtec turnbuckles and after 40 years, the bronze rods were pitted. I bought eight new bronze threaded rods in two sizes, then when I rebuilt the standing rigging, I went with standard double forked bronze and stainless turnbuckles.

I still have the nearly new hardly used Navtec threaded rods if any one is interested, PM me.

[Cheechako]

Yep Navtec. Had them originally on my Passport 47. (wire) When I rerigged I went with Chromed Bronze traditional style. IIRC Navtec are all stainless....?
