removing baby stay

My mast is 40 feet long no spreaders. Lower shrouds are at 20 feet. There is a baby stay at 27 feet it terminates just behind the hatch on the bow. I have been thinking I don' t need this stay. It may have been installed for a storm jib. But I think the attachment should be at the lower shrouds point. Any input is appreciated.
Thanks
Rich

Re: removing baby stay

Sounds like an interesting boat, any photos or diagrams to help visualise.almost sounds like a few bolger designs if I have what you are saying right?

Re: removing baby stay

Normally a baby stay is installed on rigs without double lowers to support and stop the mast from pumping, especially going to weather in a seaway. Because you have no spreaders...mmmmm!

Re: removing baby stay

If it is there, it may have been placed by the designer. Keep it.

Images?

Re: removing baby stay

“Inner Forestays”, and/or “Baby Stays” are not generally sail carrying.

They are intended to stay the mid-section &/or lower-section of the mast fore-and-aft, to prevent uncontrolled mast-bend and pumping.

An “Inner forestay” is usually attached about 60% of the fore-triangle height above the deck.

The “Baby stay” is usually attached in the region of the lower spreaders.

If they are sail carrying, there needs to be fixed or running backstays to counter the forward pull at the mast attachment point. I wonder if there are running backs on the boat? The need for running backstay is dependent on whether or not they would interfere with the mainsail, so on a multihull it may not be an issue.

Re: removing baby stay

I just found a drawing of the sail plan. It does not show this baby stay. The reason I thought it was supposed to be for a storm jib is it has its own halyard. I also noted the drawing shows my boom to be about 3 feet too short. My boat was originally rigged as a ketch but has no mizzen now.
I might add that I pulled the mast to do an inspection as it had not been down in about 10 years. Good thing I did as the step wall weld has corroded away. The only thing holding the mast in place was the downward pressure of the rig and the bolt heads.

Re: removing baby stay

Redhorse,

Your boat's baby stay may have been added after a PO saw the mast pumping and wanted to stabilize it. The halyard above it would then be the pole topping lift.

So, I wonder when it went mizzing? Sorry, I just had to say it.

Re: removing baby stay

I guess I should not have been mizzing around with it.
getting back to topic. I think I will just pull the halyard and leave the baby stay for the time being. The previous owner installed the mast which came from another boat. The suggestion the halyard may be for a topping lift is probably correct. Something not necessary on a multihull.
