new halyard

I'm finally replacing my rope to wire halyard with all rope. My manual says the current rope is 3/8 to 3/16 wire. (the current rope looks bigger than 3/8 to me ?)
If I go with all 3/8 rope any issue with fraying since it shouldn't slip into the wire groove ? Can I go with 7/17ths or even 1/2 ? bigger is better on the hands ??

Re: new halyard

You may need to replace the sheaves since wire has a different groove profile than rope, and old wire sheaves are often damaged.

In terns of strength, a 3/16 amsteel halyard will be at least as strong as the wire you are replacing, but may be difficult on the hands. You can splice an amsteel length onto a larger end piece for handeling (texen or sta-set are common choices).

If you want to go all the way to 1/2" you also will need to look at replacing all of your deck hardware. Must small boat stuff won't be sized appropriately to handle line this size.

Re: new halyard

Hi TBG, you will most definitely have to replace the sheaves at top of mast. I did a major overhaul of my P-30 last year ( still working on some finishing touches). One thing I did was remove the sheaves and cleaned them up with a wire brush. They were pretty scraped up from the cable. Also, the sheave it self is not designed to run rope. I am replacing my halyard this month, and staying with the rope to wire. Good luck

Midnight,

Any wire sheave that is smooth can handle dyneema. But you would need to do a rope to rope splice instead of the rope to wire.

Frankly I can't stand wire halyards since I have too many scars from where I have been punctured. But whatever works for you.

Re: new halyard

Hi Stumble. Not familiar with dyneema. Would prefer rope but didn"t think 3/8ths would be smooth thru the sheave. Does it hold up well as far as fraying ? Will have to investigate and see if this is feasible, thanks. This is what I like about this forum...many different perspectives.

Re: new halyard

Dyneema is a relatively new line to the market (about 10years ago) that will be stronger and have less stretch than the wire you have now. Is pretty resistant to UV damage, and because you can size for size replace running rigging wire with it does not require replacing un damaged wire sheaves (damaged ones are another story).

For all intents and purposes there is no reason to ever use wire as running rigging anymore.
