My forstay had a closed turnbuckle, which I replaced with an open turnbuckle. What's the deal with the closed ones?

The connection on the rigging side (top), the screw in to the turnbuckle does not have a hole for a cotter pin, so I've got to remember to add a lock nut on that side of the open turnbuckle.

Yup--closed was a bad idea. I'm surprised the upper screw doesn't have a hole... Can you find somebody with a drill-press? If not, in addition to the lock-nut, borrow your wife's red nail polish and paint a little stripe on the threads just above the nut. Then check it periodically--if you see some unpainted threads below the stripe... you get the idea.

<< Red Nail Polish Indicator >>

That's a Great Idea thanks. "If you see the red line all by itself... move to the front of the boat!" I was thinkin I may want a new forstay.. I've got 3 shackles as extenders now.

The original turnbuckles were galling the threaded stay ends. I replaced all them with these:

I can tighten/loosen a locknut much faster than inserting/removing a cotter pin. I saw these for the first time on a Capri 22. I've never had an issue with the sharp edges they describe. Nice, compact stainless cover to boot!

I had lock-nuts on closed-body turnbuckles on a different boat--one day the mast almost came down. I'm also not a fan of covers on turnbuckles (or shrouds), especially in a saltwater environment. Note that CD doesn't really like that model... Apparently they carry them for C-250 owners who want the OEM version. The open bodies they put on their shrouds (referenced at the bottom of that page) are as good as you can get.

I tried the new closed turnbuckles to replace the original horrible closed turnbuckles and found them to be a bad design.

The actual brass turnbuckle inside the barrel is not polished so the edges are very sharp, the big issue was the barrel will not go down over a proper swage or cotter pin without a lot of trimming and futzing. I took them all off and replaced them with real open turnbuckles and never regretted it.

<< I'm also not a fan of covers on turnbuckles >>

I put sail tape on the top of 6 of the PVC covers to hold them down, but did not tape down the backstay cover, and when the tornado came through the cover on the backstay turnbuckle rattled so hard it broke it apart. With the tape holding them down it really hides the turnbuckle, which is not good.

I love the way they look but I don't like the way they hide problems so I'm open to other options.

I constructed PVC covers like the ones described in the tech tips. They do not cover the turnbuckles and are much more durable then the ones I had previously that did cover the turnbuckles. I only have them on my forward shrouds, The rest do not contact my genoa when tacking.
