solentstay sizing

[double u]

what would be the correct diameter for a solentstay for a 40' 7,6t sloop? currently it is 6mm & PO says only moderate tensioning of the solentstay is possible as with too much tension the main forestay with the furled 110% jib gets too much slack & starts working in a seaway.

I used 1/4"or 6mm. Do you have a furler on the Solent stay? I've was able to get a shared tension between both stays that keeps the funky motion to a min.

solent is hank on, stay has a nice parking position with the curved Selden slit tube keeping it from marring the mast.in operating position it's just behind the furler.
how big isyour boat, Ecos?

Our Solent stay is 7 mm Dyform wire. Seems adequate for our ~250 sq ft Solent jib.

My solent stay on 39' offshore sailboat is 8mm.
Headstay, backstay and other stays that support mast are 10mm.
Boat is 9 metric tons displacement.

Are you sure the issue is one of solent stay sizing? I reads that the issue maybe one that, as the solent stay is tensioned, it is taking the load off the headstay rather than the solent stay elongating. A situation akin to what occurs in double headstay situations. What is occurring to the backstay(s) as the solent is tightened? Hull?

[double u]

the issue is insofar one of solentstay sizing, as there is little sense in a hefty solentstay if it can't be tightened all that much anyay because of the typical "double-headstay-issue". these 6mm just seem quite thin in the stays parking position beside the 10mm Dyform of the lower verticals...

tensioning btw is hydraulic on backstay & Wichard ratchet tensioner on solentstay
rig is fractional, no runners, swept back spreaders (all of which limits available headstay tension of course)
