I can only think of two reasons for using a babystay - One is to help
introduce mast bend in heavy air to flatten the main. Second is if your
mast "pumps" in heavy seas. It helped on my previous boat, an Ericson 30. I
have a babystay on my boat, and I rarely use it. It came on the boat with a
track on the foredeck, and a rope clutch to the port side of the mast. The
adjustment leads through the rope clutch to a spinnaker halyard winch. If
the conditions I mentioned aren't exhibited on your boat, forget the
babystay.

Does your rig already have fore and aft lowers? If you do a baby stay may not 
add that much extra support.

When I re-rigged Calypso I used Briton Toss’s rigging book to calculate the 
loads on various shrouds and rigging elements.  IIRC the aft lower shrouds can 
carry more load than most other elements.

One of Calypso’s past owners removed the aft lowers (to allow the boom to 
travel farther forward) making the baby stay much more important for rig 
stability. This is especially true when sailing in choppy seas to prevent mast 
pumping.
(Some boat racing long downwind races, Transpac for example, rig temporary 
forward lowers to support the mast in case the pole gets stuffed into a wave.)

Calypso’s mast section is massive compared to more modern rigs. I have always 
assumed Bruckmann’s had a C 61 section hanging around the shop, cut it down, 
added some taper towards the top and called it good.

Calypso’s baby stay uses a hydraulic tensioner with a fast-pin to release it 
for spinnaker gybes. The deck fitting is similar to a chain plate. Originally 
it terminated to the bulkhead just below. (A C 39 I raced several Transpacs 
on with it’s baby stay anchored to the same bulkhead we could lock someone in 
the head by pumping up the baby stay and distorting the deck/bulkhead.)

Today Calypso’s baby stay is anchored to the hull with a tie rod/turnbuckle 
combo through bolted to the hull. When we recently rebuilt the bulkhead owing 
to rot issues we found indications of stress damage from the original baby 
installation.

My 1982 C 32 has the baby stay and it’s a track

So, I believe that my 82 C 32 had the option for a babystay.  It's listed in 
the brochure, and there is a fitting for what looks to be a t-ball fitting just 
above the spreaders.

No deck fittings on my boat though.

Has anyone gone to the bother of installing the deck fitting?   If so, would 
you mind advising me on how you went about it?

Did you go for a fixed point, or track?  Chainplate to bulkhead; transfer the 
loads through deck to stringers below or beef up deck?  Also, how did you 
tension?  How was it stowed?

I'm interested in installing the babystay to beef up the rig a little.  The 
rod-rigging is of indeterminate age, and while it has been professionally 
inspected and passed muster, I am a belt for braces guy and I was thinking the 
babystay might offer some redundancy.

I appreciate all advice and speculation offered.

Thank you.
