Closed vs Open body turn buckles

My Helms 25 has closed body turn buckles and I was planning on changing them out in the near future. What are the pro & cons of closed vs. open body turn buckles? I know it’s hard to judge where the end of the threads are on my closed body turn buckles. Is one stronger than the other? I have 5/32 wire and 1/4" pins as a frame of reference.

Thanks for your help,

Wayne

I like the open ones as you can see how much thread is left and what condition things are in. I rarely see closed ones on boats over 20 feet. i don't think there is any appreciable difference in strength.

One of the problems with closed turnbuckles is that they rust inside and you can't see it. Even stainless oxidises. In fact it corrodes faster if its enclosed. Open turnbuckles avoid this.

The terminal ends on the shrouds can be secured with cotter pins, rings, wire, etc with open body turnbuckles. This prevents the turnbuckle from loosening once the shroud tensions are set. This can't be done with the closed body types.

There are 10 kinds of people. Those who understand binary and those who don't.

Open turnbuckles tend to hold less water, which reduces the likelihood of them corroding. No real reason to ever go with closed body turnbuckles IMHO. I like Silicon Bronze hardware better than the stainless...but it is harder to find.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Thanks for the info. Looks like open is the way to go. No pros for closed.

Devils advocate:
They look cool. If you are a freshwater sailor the corrosion issue isn't really problem. But, avoid lockuts at all cost. They can create huge extra stress where there shouldn't be any.

BTW, a good place to get them from is down the street from where I keep my boat... Rigging Only is a good rigging shop with excellent prices.
