Hello all,
I want to buy a Loos guage to help me tune the rig in a few weeks, once the boat goes back in the water.
The 2004 SO35 has a Sparcraft rig with the original 1x19 stainless wire.
Any insights into the diameter of the wire used in the rig?
If not, any guesses on whether the size would be metric (ie. 6 or 7 mm) rather than imperial since the boat was made in France?
Many thanks,
John

John,
I have a Loos tension gauge that I use on my 2004 SO35. It's the larger size of the regular type, as listed in the West Marine catalog. Seems to fit fine. And it has a scale that can handle both metric and English measurements.
Hard to believe it's listed at $95 (US) for a couple of pieces of aluminum. I'm sure I paid far less, but it was a long time ago.

Looking on the the main jeanneau.com page, the owners manual in French, on page 39 of 92 assuming the english is equal, goes from 5-7 mm in diam, includes a length in Meters also.
I would get the middle size loos guage. BUT< the 7mm divided by 25.4 mm per inch, comes out to .27559 inches. so you may also need the largest size for these. The others are under 1/4" which the middle size will do at the largest. The BIGGEST one will do from 1/4" up to about 3/8" IIRC.
Upper and lower shrouds, fore and aft stay are 7mm, middle stay and both lower split back stays are 6mm, baby stay is 5 mm.

Thanks guys!
Marty, after I read your e-mail, I pulled out the manual - and sure enough, the specs are all in there. I had read the thing cover to cover earlier, and hadn't noticed these.
Don, no doubt that these gauges are a bit pricey, but I guess a reasonable price for some piece of mind.
Happy tunning...
Cheers,
John

John,
If you get one, I believe the PT2 will work, except the 7mm, then you will need the PT3 which "IS" pricey at just over $200. The 1 and 2 are about 100-120 depending upon where you get it.
I have a 2 for my boat, covers all wires but the middle uppers which need a PT1.
I can go down and look at mine and see if a 7mm works in abit. boat is all of 5-10 min away.

Thanks, Marty.
I think I'm in good shape. I had a look at the Loos website. The PT-2M is the metric version. It covers 5, 6, and 7mm - so the entire range of wire on the SO35.
It runs about $120. Not cheap, but nothing for these boats are...

John,
They are expensive, but as you say, worth it when tuning a rig up.
Not that this will or will not work, my local YC bought a PT1 and 2 for club member use age. We have not bought the 3, so far no one has said they need that size. I borrowed/actually I was in charge of buying the clubs gauges, so I have figured out where on my PT2 the numbers need to be for the one wire that is too small. I can do a quick tune/verification of the stays/shrouds before heading out.

For my SO34.2, I needed two Loos gauges, the PT-2m and PT-3m. The PT-2m is not quite big enough for the largest shrouds.
Don't know the wire sizes for the SO35. There's one on my dock, which I might check when her owners return for the season.
I've found it necessary to attach the gauge, take a reading, remove it, and reattach it, perhaps 3-ish times, before getting consistent results. Be careful that the cable is centered in the pathways.

Thanks, Karl.
We did determine the diameters - they were in the manual, as Marty pointed out. 5, 6, and 7mm diameters, so just the PT-2M works for all wires.
Thanks for the tip on getting accurate readings from the PT-2M. The instructions that came with it mention the need to lubricate with a slicon lubrican frequently. So that may be the key.
