Something is wrong.....can't tell you what without seeing it but
definitely something is wrong. I have a split back stay and I attach
mine every Spring single handed...I don't need a second pair of hands, I
don't need to attach the main halyard to crank the mast back.....the
forestay and shrouds are attached and lastly I simply pin the split back
stay and tension the two turnbucles and attach the adjuster lastly.
I think getting a rigger to investigate is a logical thing to do. Let's
us know the outcome.

Dear listers- Thanks for all the advice and observations. I actually
worked on it for a few hours yesterday afternoon and now I really
don’t know what is going on. I checked the mast with no backstay on
and it still showed a few inches of rake. The forestay had a
significant arc to it and felt very loose. I had previously taken
most of the tension off the shrouds. I tried to pull one side of the
split backstay and could not pull it far enough to pin it. I don’t
know how you could possibly do this with the adjuster attached as
there is no way to get it out of the way and near a neutral position
until both backstays are attached- so I took it off. Then I let off
the mainsheet and vang, attached the halyard to the end of the boom
and cranked the boom down with the winch. I looked at the forestay
and it was still very slack. I loosened the shrouds more, but no
change. I still could not pull it down enough to attach one side, let
alone both. So I rigged a mini block and tackle between the U bolt
and the turnbuckle and was able to pull it down enough and hold it
while I got the pin in. With another person there leaning on the
wire, I might have been able to do it without the block and tackle,
but since the boat is in the water, it is hard to get in position to
pull on the wire and put the pin in at the same time. I ran out of
time to try the other side, but it seems like something is not right
with the rig if it is this hard. I have not changed anything related
to this since I bought the boat, so I find this very confusing. I
doubt C&C designed it to be this hard and there would be no reason to
since you could just make the backstay longer. One other thing for
those who have other C&C designs. Unlike my previous 34, there are no
deck level wood blocks to adjust mast rake, nor any adjustment on the
mast foot. The mast goes through a hole in the deck that is the size
of the mast, so no rake adjustment there.
Anyway, I decided to contact a local rigger I have worked with to see
if he can help figure out what is going on. I will report back when
we have it sorted out. Thanks- Dave

When my two back stay turn buckles are tensioned to where I like
them, no adjuster pulled on, there is approx. 2" showing on each one
on the inside of the turn buckle.....I thread both sides of each turn
buckle equally.
When attaching to the back rail when stepping the mast, both are
loosened off approx. 1 1/2 inches of the 2" and they can be pinned no
problem.
I take my adjuster off the back stay each Fall and put it back on the
Spring.....it is not put back on until I have the two back stay(s) on
and tensioned so the adjuster has no part in getting the back stay
pinned.
I don't have a halyard attached to the back rail or anywhere.....I
don't use a halyard.....never have.....with the mast in the mast
step, blocked at the base, the mast shimed in the collar, the
forestay on, the shrouds tensioned, my mast isn't going anywhere. A
halyard is always added protection but I will never use one.
Trusting this helps.

They said was that there were only a few threads engaged on the
turnbuckle and they were leaving it to me to tighten it further. I
thought Josh’s idea to take tension off the backstay with the
halyard makes a lot of sense. I will take a look at that today. I
know the backstay adjuster was mostly loose as I had pushed it up
with a pole this spring when I was playing with shroud adjustment.
1. How much tension should there be with the adjuster up as far as
it will go without a pole pushing it. Should there actually be
slack to put the pins back in with the turnbuckles loose but
attached without taking tension off with the halyard as Josh suggested?
2. I am presuming that it is safe to work on the rig with the
backstay detached (meaning the mast is still well supported by the
deck, forestay and shrouds)?
Thanks- Dave

My boat has the same setup for a backstay.....split with an
adjuster.....I unstep and step my mast, however, I have no problem
attaching the split backstay which I am the one usually doing it.
I leave the turn buckle(s) attached and simply remove the split
ring and pin in the Fall and in the Spring, one at a time put the
pin(s) in......and when I do this, the forestay is always attached
first for obvious reasons.....the length of the forestay is
'set'......when the backstay is attached, the turn buckles are
tightened.
I can see where it would be difficult if the backstay turn buckles
were removed......then it becomes a two person job to attach
them.....you really need one person pulling back and down on the
backstay and the second threading the turn buckle....it can be done
with one person but a lot simpler with two.
Just curious, when the backstay is attached and tightened, how much
'thread' is showing inside the turnbuckle? Just wondering if your
forestay is too tight.

My boat has a split backstay with an adjuster that is pulled down
with block and tackle to pinch the split and increase tension (Is
there a nautical name I should know?). My boat was splashed today
and the yard crew complained for the second year about the
difficulty reattaching the backstay. I don’t think previous yards
even disconnected it, but something about their sling and lift
system means they have to come in with the sling from the rear
with no backstay. I am pretty sure the mast has a slight backward
rake, so I can’t see why the length of the backstay would be a
problem, but apparently even with the turnbuckles and adjuster
loosened, they can barely get it reattached. I can’t come up with
a reason why they would have such a problem and if it means that
something is not right with the rig. I will check the rake again
tomorrow now that the boat is floating and level, but it has
always had some amount of rake as measured by a weight hanging
from the main halyard. Any thoughts on something I might be
missing or is it normal for that kind of backstay to have limited
adjustability? Thanks- Dave
