Help needed with stays of 40DS

[sailbleu]

Hi there , could anyone help me out wih a small problem I have with the stays.
Yesterday I've replaced all of them , needs to be done after some years right.
Brought in the old stays and received (after payment of course) the new ones.
I wasn't aware that there is a difference in size ( 7mm and 8mm) between the bottom side stays. There's two of them (on each side that is) .
One is slightly away to the front fixed onto the deck .
The other next to the fixing of middle and top stay.
I was wondering where the 8mm should go and consequently where the 7mm ends up.

Thanks for the advise .

Regards

I'll be at my boat again on 4-13 if you can wait till then...

Oh thanks Craig , of course I can wait.
Stupid me , if I would of known before I would of had them made in 8mm both.
Just noticed it when I picked up the new rigging.
Jeanneau's way of cutting costs , 1mm for about 4 to 5 meters of wire , times two that is.
I've checked on the riggers site , difference in price is 30 Euro (times two again) between 7 and 8mm , retail price .
I guess all small bits count .

Think of it as Jeanneau trying to minimize your windage, on that section by over 10%! Plus weight aloft.

Probably NOT jeanneau, more like the designer doing as zanshin mentioned. Keeping things light wt and as strong as one needs for the design task at hand. If you wer going to up the 7mm size, you would want to up the 8 mm size by one mm also. Of course this would keep thing in content some, and one can then tighten the wire to the appropriate spec as it was intitially. Along with allowing you to probably handle a slightly higher wind speed.....or maybe if it turtled for the rig to stay on.....

Reality, there was probably a reason for different wire sizes. My older 85 arcadia is this way. where one needs more strength, I have thicker wires, where not, lighter. my wires are slightly smaller being as I only have a 38' total mast height.

still too cold to go to the boat. I think I found what your looking for in the boats manual available at Jeanneau's web site.

anciensbateaux.jeanneau.fr/doc/proprietaire/manuelproprietaire_2_20080307_979202So40dsgb.pdf around page 23 as marked on the sheet (much later via adobe's navigation bar),

Great stuff Craig , it's not only the answer to my question , it's also one hell of a link.
Already neatly stacked onto the hard disk.

Thanks alot.

Kind regards

As-built on my 2000 SO40DS:

Lower inner shroud forward 7 mm
Lower inner shroud aft 10 mm
Mid Shroud 6 mm
Top Shroud 8 mm
Backstays 7 mm

These dimensions are from notes taken during the pre-purchase inspection a year ago. Despite the chill, I will be working on the boat again this weekend and will verify with calipers.

I cannot find tension setting data in my log book. I'm reasonably sure that I have a spreadsheet with vector analysis of them somewhere. The boat being on the hard and with her winter cover still in place, it's not easy to measure them at this time.

Wow Karl , those are some strange sizes you got there. I was under the impression all 40DS ' had the same rigging, obviously not.
Here are mine:

Front 10mm
Back 8mm
Top 8mm
Mid 7mm
Lower front 7mm
Lower back 8mm

By the way is it still that cold in the US ?
We are finally getting some spring (summer) temps over here in Europe , 70° F over the weekend .
The shorts skirts will be hopping around again after the long cold winter , the milky white legs will unfortunatly be part of the show I guess

snowed this morning in Michigan. Melted in the afternoon...

Brain failure. My boat is an ordiary SO40, not the DS. FWIW, here are the numbers measured today:

Lower inner shroud forward 7 mm
Lower inner shroud aft 10 mm (I can't imagine any structural need for this size)
Mid Shroud 7 mm
Top Shroud 8 mm
Backstay split bridle 7 mm

These numbers match those in the owners manual. The forestay and backstay could not be checked without ascending the mast.

Weather in the northern half of the US has been colder than average since February. There have been a succession of storms from the Pacific that have tracked across the country, while high pressure from Canada's praries eastward has moved the storms along and mostly prevented warm, moist air from rising from the Gulf of Mexico, at least in the Midwest. A year ago, most boats in the yard were uncovered and ready for launch. This year, most are still covered, and the colder weather seems to favor weekends while the warmer happens mid-week, if at all. Launch schedule is 7-10 days delayed. We're hoping for a "normal" May this year, as that month and June were much cooler than normal the past two years.
