Steering Cables - Steel or Stainless Steel ?
well I was doing a little boat yoga in the Lazzerette. Think the pose was sailor changing raw water impeller. Anyway looks like my steering cables have one or two fishhooks. It looks like the cables are regular steel but all greased up. Though I'm not 100% sure and the grease is dark and so is the cables.
So should I replace them with steel 7x19 or stainless steel 7x19. I think the cables are probably original and almost 40 years old.
Stainless is about 10 times the cost of regular steel cables. Being that the old cables made it this long, I'm leaning toward plain steel cable and just grease it up.
My steering Pedestal looks to be a custom/hand fabricated type
What does the collective think???

Re: steering cables, steel or stainless steel
Stainless. Gal wire is cheap, but do you really want the rust stains associated with it. Unless you feel like crawling under the cockpit with cans of lanolin every six months.
My 2 cents..

Just replaced mine. Stainless. Good for the next 40.

I have replaced a lot of my wire lines with dyneema. Fantastic.
I am wondering if anyone has used dyneema as a steering cable replacement.
That should be ideal. No?

Talk to your rigger?
If you can get in touch with the original maker of your steering then they may be able to advise.
Otherwise measure the diameter of all pulleys and pull your cables off. Take them to your rigger and ask them to make up replacements. They should know the right type and size of wire.
Do get new clamps at the same time.
If the wire is too large for the pulley diameter then the steering may be stiff.
Don't forget to visually inspect all parts of the steering for damage, particularly the chain ends and cog. Do lubricate the bearings (Your rigger should have recommendations).

Re: Steering Cables - Steel or Stainless Steel ?
Going to disagree with some of the above posts. If the steering cables are the normal, internally run cables, then galvanized will far outlast stainless. Galvanized steel has superior fatigue properties to stainless. It it fatigue, from being bent as it runs around the pulleys, that has caused the fishooks you're seeing. Galvanized steel will run far longer without fishooking. Cover it with a good grease and it will both last longer and save you a good amount of money.

I did mine using Amsteel blue. excellent result. made 2 so there is a spare. I found it initially has a little stretch so for the first few weeks I check it and tension it. I have old style edson quadrant and the steel cables have to make a fairly sharp turn onto the quadrant. Grteat place for stainless to fail. the round quadrant would be an improvment. The amsteel looks like new I think its in its 3rd year.

Re: Steering Cables - Steel or Stainless Steel ?
You weren't hoping for a consensus were you?
I would talk to a rigger about your choices and ask him about Amsteel blue. It sounds like a great material and easy enough to carry a replacement piece in your spares kit.
Amsteel Blue Synthetic Rope

Re: Steering Cables - Steel or Stainless Steel ?
Yes, I would go for synthetics too. In addition to Amsteel, I would take a very good look at Dynex Dux (is there something like overkill for strength of steering cables?)
Here you see some Dynex Dux with some hardware that is specially made for it:
ciao!

Re: Steering Cables - Steel or Stainless Steel ?
exactly mine is tensioned with similar fittings and appropriate eye at the quadrant. I think dynex dux would also do the trick.

Re: Steering Cables - Steel or Stainless Steel ?
Lordy, Well at least I did not start an anchor thread. The engineer in me say regular galvanized steel will be stronger then stainless. Stainless means no greasy wires which is a big plus when I'm doing boat yoga in the lazzerette. I have a V-drive engine so the front of the engine is faceing the rudder post.
I worry about work hardening with stainless. The new synthetic ropes look pretty good, but I need something I can fix / replace in out of way places and my knot work leaves much to be desired. Though I have learned to do an eye splice in double braid. I'm also shy about being on the bleeding edge. Plus want it simple enough so I can deal with it too
Looks like I need to ponder this a little more.
Thanks Guys!!

Re: Steering Cables - Steel or Stainless Steel ?
Galvanized for me. Wire rope is made from "improved plow share steel" (what ever that means). Think of all the cranes, elevators etc. that use this type of wire rope and the cyclic life it has. Why argue with success? As to maintenance, they make aerosolized penetrating grease but it can be a bit messy when applying.

I agree, in addition, steel wire is stronger for the same diameter than stainless. I would only consider stainless if you have a major corrosion problem.

A splice in these synthetics can be done in seconds without tools... nothing like double braid horror... these are hollow-braids (single-braid) so you basically loop and burry the end inside the hollow tube. I would also say this is not cutting edge at all... think it's been around for 20 years at least.
The only question sometimes put to the synthetics option is about UV damage... which you don't have with the steering cable!
Look how I did this splice with an small piece of cover where the thimble went: (okay, used a tool and tapered the splice :-)
ciao!
Nick.
