my outhaul line is currently the stock setup with a 2:1 purchase inside the boom, which has a 5/16" line running outside, with a short piece of 7x19 3/32" wire connect through the end of the boom to the sail.

does this short piece of wire need to be wire? Since i've got the boom in pieces i was thinking of upgrading to a higher purchase, but i'd like to alleviate the wire and maybe use a short piece of vectran.

the 7x19 wire looks like it's a little less then 3mm probably 3/32" wire which WM shows as 1760 breaking, 3mm V12 single braid vectran shows 1900 breaking. Even if my micrometer is a little off, i think we're still in the zone for breaking strength, is there any other reason this should be wire?

I'm a C25 guy, but isn't a few inches of the end of the outhaul exposed to sunlight, where it attaches to the clew? Vectran is degraded by UV. Stainless is not.

Ah, yes, good point.

However, according to New England Ropes

"Very little degradation from sunlight. Can be used outside over long term if inspected regularly."

I might still go rope instead of wire, just because of my utter distaste for wire (been snagged/cut/poked too many times)...

I'm a little surprised by a wire out-haul on a C-25--never seen or thought about it. Mine was some nondescript double-braid rigged for 2:1 purchase. That and my newer Krypton halyards withstood plenty of UV--the core of double-braid is protected from it and takes the load.

Obviously I don't like being snagged by a wire, but I have always considered it a clear warning that the wire needed to be replaced. I've found that as soon as I replace the broken wire, I don't get snagged anymore. I'd rather get a little snag than have the wire fail suddenly and without warning under load.
