[Rhodes22-list] Standing rigging thickness

[James Nichols]

Oh yeah, that was the reason for the needed higher tension on the 5/32 vs
the 1/8.  10 -12% of the breaking strength on 5/32 is significantly higher
than the breaking strength of 1/8.  According to the guide, it's 550kg
higher which turns into 85kg more tension (another 210lbs tension) on the
Forestay.

Thanks for the info Dennis :)

Hopefully I attached a rig tensioning file correctly. Rhodes' 1/8" wire is
about 3mm, so the recommended tension is 145 kg (or 320 pounds) on our
masthead forestay, and 110 kg (240 pounds) on the shrouds. On the Rhodes,
this means setting up the forestay length prior to raising the mast, then
tensioning each of the backstays at 160 pounds. The forestay length will
affect the mast rake, which will in turn affect weather / lee helm.

It goes without saying that you need to have the mast perpendicular to the
deck as you tension the shrouds. Only the proper dose of rum can correct a
mast with a 10 degree list :-)

The guide goes on to say the lower shrouds should be about 95kg (210
pounds), or 10 - 12% of the wire's breaking strength. Make sure you tighten
them evenly - an 'S' bend in the mast ruins the boat's aesthetics.

Having said all of the above, it's just a guide. Lacking anything better to
do, I try to follow the directions - which I can generally do. 

On a good day.

John,

180 pounds?  That seems a little more than hand tightening.  You're putting
unnecessary strain your chain plates and everything else.  Lighten up and
save a buck.
