Damage to rigging?

Can this cause any damage? I made a bracket to hold my horn on the backstay. What concerns me is the horn will most likely always be rocking a little causing the the backstay to to twist back and forth just a little. I know there are radars mounted on backstays so I assume it's normal.

You can see the way it's mounted in the picture. But for now it's just at a low level so I could assemble it. Once I feel it's safe I'll put it up higher.

Picture will be posted in a minute.

Thanks.

Re: Damage to rigging?

Shouldn't be a problem, as those types of clamps are sometimes used to connect 2 pieces of wire together, or when forming an eye n the wire. Including in ship's rigging, or more commonly, on telephone pole guy wires.
Just don't go nuts tightening them down, no pun intended.

One tip is to wrap the stay (wire) with tape, before applying the clamps. Friction tape, athletic tape, or even electrical tape. It provides a better overall grip than metal on metal in non-structural applications like this.

Damage to rigging?

If you use one to make a loop in a wire, just remember " never saddle a dead horse" meaning the saddle needs to be on the wire carrying the load.

They are Stainless?

Re: Damage to rigging?

Thanks for the replies. Yes, they are stainless. I think I'll move the horn a little closer to the backstay (it's about 5" behind it). That way there will be less torque on the stay as it moves side to side with each wave/wake ever so slightly.

Re: Damage to rigging?

I moved the horn closer to the backstay so now there's not as much of a "lever" on it. There is still some twisting motion with the waves but I think it should be ok. It would be better on the forward side of the backstay because the weight would be closer to the stay. But then I would have problems with the toping lift catching it. All that's left to do is attach the wires, test it again, and then put it up to the height I want it.

I forgot to add pictures to my last post. For some reason I can't do it from my phone. I'll add them next time I turn on the computer.

Re: Damage to rigging?

With the concerns about it swinging, might you guy the horn or the bracket either with some small diameter cordage, or bungee cord?

Re: Damage to rigging?

I think that's a good idea. I recently replaced some lifeline so I might be able to use that wire. I could possibly attach it to the arch. That would hold it still.

I didn't want the horn on the arch because 1) it wasn't high enough and 2) the wiring would have been much more difficult.

Thanks,
Larry

Re: Damage to rigging?

Some years ago we were close reaching into a strong headwind. A very loud bang got everyone's attention and we quickly realized the backstay had parted. Post mortem was that the radar reflector had been swinging in the wind, attached to the backstay and had fatigued the wire. Really bad idea.

Re: Damage to rigging?

That's the sort of thing I've been worrying about with this. My original thought was if there are backstay radar mounts there shouldn't be a problem with just a horn. But then I looked closer at pictures of radar mounts and they all have a stabilizing bar with the backstay.

I think the idea from Uncivilized should be able to stabilize it so there wouldn't be any extra stress on the stay.

Thanks for that story. It puts light on how to do this properly, if at all.

I'd like to hear from others that have either tried something like this or are rigging specialists/engineers. Anyone?

Re: Damage to rigging?

Given your concerns, & the plethora of other ways to mount this, I'd opt for Plan B. Whether that's attaching it to your arch, a spreader up the mast, or somewhere else entirely. Why put it somewhere which will forever leave you with a sense of nagging doubt. A proverbial Sword of Damocles, only in the rigging sense.

Re: Damage to rigging?

I can't tell you how much I loathe anything attached to stainless wire. I know it is done commonly, and most people get away with it for years without issue. But the problem is that any tight fitting connection on stainless sets up the occasion for inter granular corrosion. This is somewhat acceptable of lifeline stations or the like, but on rigging, which is not just mission critical, but also can be life critical I think it is a terrible idea.

Ever priced out a new rig? In most cases a broken shroud means a broken mast, and a broken mast totals the boat.
