[C38] Bob Stay

Thu Nov 29 21:30:03 EST 2012

If your purpose is to fly a code O, which I believe is a lite air reaching asym, you don't have to make mods to our one design racing boats.  About 6  years ago Quantum made one for me and it performs great.  It is hanked to the standard bow anchor roller and uses a short PBO  pigtail to bring the tack just above the bow pulpit.  Luff tension is applied by the spinnaker halyard.  But if you are trying to make a J 38 out of a Cat 38 then I can see it requires what Joe has done.  The next step would be to increase the boom length and use running back stays.  For me I have enough boat work just trying to keep up with the maintenace and maintain the boat for one design class racing when available.Cheers, Steve O

Joe, I installed a Seden bowsprit just like yours, but with a 4" diameter on a Hunter 44' ( that's what Selden recommended) for a code 0 sail furler.  We installed a PBO bobstay on a Wichard U-bolt just like the one on the link. It works great, and the breaking strength is around 18000lbs. I think it will work for you.. They are used on some sailboats as chainplates, so that speaks of what thy are capable to withstand..

You don't  we'd a turnbuckle, or wire. The PBO will be the way to go. I think that Les is referring to the inner forestay installation on Fat Cat.  Hope this helps.  Regards, Max Soto

So basically what you want is an attachment on the bow to tie to your  bowsprit/karver  roller  in order  to keep the tension on the halyard?   Why not use a pad eye  low on the bow below the anchor roller with wire and a turnbuckle up to the bottom of the sprit.   If  all you’re doing  in essence is tacking the spinnaker to the roller which is attached  to the sprit and then carrying the load to the hull, in order to keep tension on the halyard, you only need to worry about a load somewhere in the 2500-3500 pound range.   Seems like a wichard pad eye with two 5/16 bolts and a backing plate will do what you’re looking for.

    We are many thousands of dollars beyond your fix. We have a Seldon adjustable sprit which projects out 42 inches past the head stay. (PHRF hit us 15 seconds fo our new 19 foot J. ) We have a 1/2 oz assy chute made for the 19 foot J which is fast in light air.The Karver furler sits on the end of the Seldon. The karver needs a very tight halyard so pressure upward on the sprit thus the bob stay. Got a drawing from a J-120 from Sailing Anarchy fix-it thread.  So here we are.

I drew up some plans to add a 13” extension in order to get the tack for the asym out past the bow pulpit, but decided to wait and see if some of the other tweaks I did will solve the issue first.   You might be able to add 13” of ¼ stainless reinforced on both sides and then tied to the hull with a wire tie rod.   Ill try to send a scan of my drawing in the next few days, (Going in for elbow surgery tomorrow and not sure if ill be to work on Friday or not) but will forward as soon as I can.  The Karver can mount to your bow sprit too cant it?   Steve#312 PeregrineSeattle From: listserve-bounces at catalina38.org [mailto:listserve-bounces at catalina38.org] On Behalf Of Joseph Launie

Subject: [C38] Bob Stay Hi,
    I am going to put a bob stay on Macavity to handle my Kaver top down chute furler. Does anyone know where I can get a bracket built for the bow  of the boat? I want it to be v shaped stainless following the shape of the hull with an eye to swage the bob stay to. I would also want backing plates for the inside of the hull. It needs to be strong. The bob stay itself will be 11 mm spectra with a cover rated at 19,000 pounds.  SAnta Barbara is a good place for olives but not stainless. Joe
