Re: Bobstay material: ss 1x19 or Galvy chain?

I changed from wire to a solid rod 23 years ago after the lower swagging cracked - it spends a lot of time in the water when sailing and am still very pleased with it.

Hi Test 3/8 in. chain is less than 1/2 the strength of 3/8 in. wire.

And I have a solid 1/2" s.s. rod with welded clevis eyes at each end ... No problem, as long as I don't bend it on a dock somewhere.

Re: Bobstay material: ss 1x19 or Galvy chain?

SS below waterline has corrosion issues which are not always obvious with wire which is more prone to crevice corrosion. Chain is very easy to spot corrosion. Silicon bronze rod is more corrosion resistant below water, but needs to be bigger in section than steel. Dynema is also an option but needs to be chafe protected.

Re: Bobstay material: ss 1x19 or Galvy chain?

Here's an opinion based on twenty years of full-time cruising from California to Sri Lanka: go with chain. Use the same size as you anchor chain and you always have the material to make a new one in the out-of-the-way location. It is the lower couple of links that go bad first, and they can be cut off and the turnbuckle adjusted a couple of times before you have to replace the chain. You can tell by looking at chain when it needs replacement, this is NOT true of wire which can fail without warning. If you must walk out on the bob stay to make a small repair or free a jammed line, chain is MUCH easier on your feet than wire. It is quite easy to pull a length of (clear) plastic hose over the bob stay to prevent chafe and the grinding of the anchor chain at anchor. But you will lose a tiny bit of performance due to the increased weight. Good luck and fair winds

Wow, thank you all!

Whole bunch of issues I hadn't remotely considered, and options I didn't know existed!

Cheers

Matt

Re: Bobstay material: ss 1x19 or Galvy chain?

One thing with galvanized chain. The lower links tend to rust quicker due to being attached to a bronze or stainless steel fitting. Handy to have enough length to cut a link off every so often , plus end for end it occasionally.

Re: Bobstay material: ss 1x19 or Galvy chain?

My bobstay is 1/2" SS rod with a turnbuckle at each end. Been fine for 31 seasons, so far. I'd replace it with the same thing in a heartbeat. It's a piece of NavTec rod as a matter of fact.
