What Dwight is referencing is a race we did with a Kirby 25 and were
embarrassed on the race course. And we were especially bad on starboard
tack....we kept wondering all day what was wrong....almost blaming one
another for our poor performance, e.g. you can't be pointing high
enough, you can't have my sails trimmed. After the race, first we
discovered the shroud turnbuckles were not pinned.....I thought they
were because I thought I pinned them after I tensioned rig tension.
Dwight discovered by applying Pythagorean's theorem that the top of the
mast was out of column by 18" to port. Any wonder why the boat was not
performing the way it/we previously did.
That never happened a second time!
The 32's rig is set at cap shrouds 1,300 lbs., lowers 1,200,
intermediates 500 lbs., backstay at rest 1,000 lbs., babystay 600
lbs......haven't measured the headstay tension but it is about 4" to 6"
bowed with a 135% under power. And since I stopped racing, I have
become lazy and am just happy to have my mast in column and the rig not
bending/stressing the boat, and go sailing almost every day during our
sailing season..... averaged over 100 days per season for the last 5
years on AZURA....and that does not include a dozen or so sails each
season on other people's boats.

I think you might have learned the hard way about what rig tune means
in that race we had with the K25 when we got whooped big time,
especially on stbd tack...no good at all if the mast isn't plumb, right???
I am not sure if anyone can feel tension as accurately as the gage
does it and the less expensive Loos gage for wire rigging ain't too
bad either...i like it, at least it tells me stbd is the same tension
as port but you have to use it right...everybody here, don't ever
underestimate the importance of rig tune for performance, and that
means perfromance as a function of expected wind strength and as wind
strength varies so does optimum rig tension on these older boats,
especially for pointing...y'all have to find out the hard way by
experimenting with your own craft...a gage is essential for that
experiment...Rob has the right gear for tuning rod rigging, he sets
his rig up year after year for what works best on his 32, he doesn't
race Azura so he doesn't vary his optimum rig tension for wind
conditions all that ofeten, maybe a little more tension when the heavy
fall winds hit here...no matter he likes what he got and that's OK
until another 32 on the same point of sail blows him away...everyone
is still learning, me, you and him too, get a gage and have some fun
experimenting...watch you angle to apparent wind and your speed over
ground on the GPS!!!

On everything up top on the standing rigging, I now use only SS
cotter pins.....this is because on several occasions, and I can
not explain how it happened, the split rings vanished. Luckily,
nothing fell down before the missing split ring was detected. I
have no explanation how the split rings disappeared but I do know
that since being replaced with cotter pins, there has not been
been a missing pin.
The thread Subject is "rig tuning"......on that note I have rod
rigging and a Loos RT10 tuning gauge is a must for me......I can't
pull on shrouds and tell how much tension is there. Now someone
will chime in and tell me to measure my threads in the
turnbuckles. But how do you initially do that without a reference
point with the benefit of a gauge.
When we were campaigning our Kirby 25, we made rig adjustments
depending on the conditions. We still used a Loos gauge to take
the guessing out of the equation.
I shouldn't admit this but I will.....on my shroud turnbuckles, I
use the small plastic pull/lock strings (or whatever they are
called). Once I get my rig tuned early in the Spring after a few
sails, it stays that way all season unless I adjust it after
periodic checking with the Loos gauge and sighting the mast, of
course.

Tim,
How often do you make adjustments? Do you have a tension gauge
for rod rigging?

I got those (wrap pins) last year - and am very happy with
them - no sharp edges, no messing around with rigging tape to
make adjustments.

A comment was made to me the other day that if an
insurance company sees split rings at the rigs
turnbuckles (vs cotter pins) that coverage will be
null and void. I found nothing in my policy stating
this detail.
Anyone else ever hear of this?
Thanks,
Pete
