Thanks Andy--
My terminology may be incorrect but what I call check stays are mounted at two
different heights on my mast and are separate from the rod backstay, which is
adjustable via a hydraulic cylinder. This being the case, I suppose some might
call them 'running backstays' but I already have a back stay so I go with check
stays.
These stays were originally rigged by C&C so that the upper and lower join
together about 4 ft off the deck and each stay (at different heights on mast)
can be adjusted separately. Originally my boat had an adjustable baby stay
which I removed as too much of a PITA (for tacks upwind and releasing for
downwind work with a spinnaker pole). Since my spreaders are basically
athwartship, my sailmaker saw no need for the baby stay. I left the checks on
to add some mast stiffening fore and aft.
The final check stay connection then goes thru a 4-5 purchase block/tackle
arrangement to a deck mounted bale. The b/t is rigged with a cam cleat which is
pulled tight on the upwind side of the boat while the leeward stay is released.
It has never gone to a winch but could if the conditions have the mast pumping
fore and aft.
Since their tension is mostly aft, they stiffen the mast against the back stay
trying to bend It in the fore-aft direction (mostly) with a fraction of the
tension stiffening the mast to weather. Whether they are really necessary, I
don't know. OTOH, since I no longer have a baby stay I consider them a means of
stiffening the mast fore and aft to prevent any pumping in that direction.
FWIW,

I just finished splicing some dyneema for the running backstays for my Baltic
47. I assume that's what you are calling check stays. So yes, I think Dyneema's
a much better option than wire. We use the boat mostly for coastal cruising,
occasional ocean racing, and occasional ocean passages.Just FYI check stays are
the lower running backstays. On a Star, the running backstays control headstay
tension while the checks control mast bend and are an integral part of sail
trim. On our boats the runners stop the inner forestay from bending the mast
too much when we are using a staysail and also stop the mast pumping when we
are beating in waves (which is my most common use). We use the backstay for
headstay tension and the runners can stop the backstay from bending the mast
too much.AndyBaltic 47 MasqueradeFormerly of C&C 40 Peregrine

Do you actually use these? Our frers 33 has check stays and although they help
with main shape we rarely use them due to added complications tacking etc

Subject: Stus-List Wire vs. Dyneema check stays
I have decided to replace my standing rigging on Water Phantom, my now 26 yr
old 1995 C&C XL/kcb.
The rigger has recommended staying with a rod replacement vs. wire to better
match the rod fittings, esp. at the mast head and to save money.
He also recommends going with dyneema, instead of wire, for the check stays.
My concern is uv damage to the dyneema which I understand has been a problem
with using it vs. wire. His response is that the early coatings used to protect
dyneema led to short lifetimes but that the newer coatings have solved that
problem.
OTOH, my wire check stays are still fine “…after all these years…”
My question is should I go with dyneema for the checks or stay with new wire
assuming the costs are similar?
Thanks,
