Well I think that's the right term for it.

anyone know where I can get the thing the spinnaker attaches to at the mast head. I found them on CD for other catalinas but not the C250(wb)

You could probably re drill whatever CD has, cut it down and it would be fine on a 250. They aren't exactly a technical piece.

Paul,
If it'll help I can take a picture of ours tomorrow (it's dark & raining right now). It doesn't look complicated to me, but maybe the picture will give you some ideas?

David, before you don your foulies, the CD pics are good, but they just don't show one for the C250. I have sent CD an email asking if they have one that is blank (no holes) that I could drill to fit.

Now, if your crane is considerably different from the CD styles, then please do post a pic.

thanks.

I just inspected the masthead casting. I'm curious..
Reading up on setting the spinnaker, the head of the sail should be forward of the furler, hence the masthead crane. And the spinny halyard must not snag with the furler either.
If I run a new haylard to a block on a new masthead crane, I'm concerned that the block will get tangled with the top of the furler.
So I was wondering what others do. Is there any sence in putting in larger sheave in place of the existing, unused, jib halyard, such that the halyard could run up the inside the mast, over the larger sheave, forwards over the casting (there is a cross piece connecting the two sides of the casting at the top) and then over a sheave in the new masthead crane, down to the block???

Just concerned about the tangle risk.

Paul.

Paul,

The owners manual has a diagram.
The masthead on my C250 is already configured for a spinnaker.
I don't have a spinnaker but I don't think you need a new masthead.

Russ, thanks for posting that img, it points out my issue.
When you look at the image, the jib haylard turns off the top of the sheave and then feeds down aft of the furler stay.

The issue I'm considering is when using the jib halyard as the spinnaker halyard, the path of the halyard from the top of the sheave to the top of the spinnaker halyard block.

The block will be mounted on the end of a masthead crane that moves it forwards further away from the furler stay. The spinny halyard however, appears to have to be able to feed through the spinny haylard block even when the block is twisted to one side.

BTW. The sheaves in the pic are much smaller than those actually installed.

Maybe someone that has a Furler (CDI) and uses a spinnaker can shead the light.

That is a common issue Paul. Once the sail goes up however the block will be forward and out so you won't get any grindage if that is what you are concerned with. You might consider on of the long hasp and clevis pin sets that have half a twist in them to extend the block out even further.

I went through the same search, Paul; never found the masthead crane for the 250. Tried running the halyard straight from the sheave to the block but it looked to me (swaying to & fro, admittedly eager to descend to the deck in a controlled manner) like a snarl in the making. However, it's quite possible & even practical to fly an asymmetrical spinnaker on your existing jib halyard, straight off the sheave, even though it's behind your furler. You wouldn't want to do it with the old-style spinnaker, but as I understand the asymmetrical it's not meant for straight downwind runs anyway; you fly it almost as a genoa. It's a reaching sail. Keep in mind when rigged this way the spinny needn't (mustn't) be brought round forward of the furled jib on every tack -- you just put the helm down and sheet it across like you would the 135, except of course you're running the sheets through an aft block near the helm.

Don't know what others have done. Certainly I'd prefer the more standard arrangement, but this worked well for us all last season, with the only downside being considerable chafe on the jib halyard where it encounters the masthead.

Paul'

Uour masthead sheave box is roughly the same as the C25. I have been using a cruising chute for 7 years using the set up Reuban describes. It works fine and tacks without any problems. The only snarl I ever had was a "head-space and timing issue".

Incidentally Paul a device called a Tacker, made by ATN, essentially a plastic sleeve connecting the tack of your asymmetrical to your furled jib, will make flying the kite much easier. A well-designed bit of gear well worth its modest price.

If you have an Asym then use the jib halyard and tack the chute inside the furler like a genoa. Just make sure you attach the tack of the chute aft of the furler drum. I have done it that way and it allows shorter sheets and simplifies everything.

Frank (et.al) my spinny (in the mail) is from a Capri, which I understand it taller then the C250, so I'll have to rig it this weekend to see if it fits under the furler. I appreciate your input about the sheets (less line to get tangled) good point.
Reuben, because of the length, I doubt I'll need a tacker, I'm expecting the tack of the sail to be pretty close to the pulpit/deck.

Russ... the Catalina drawing shows a block at the forward pin of the mast truck for a spinnaker block but a setup as in the drawing does not work with the CDI furler as the halyard line will foul with the furler.

Needed is about 3-4 inches of extension that is held in place by the forward pin having the result of keeping the halyard forward and clear of the furler when the spinnaker halyard is made to the bow pulpit and not in use.

I don't know if this is a problem with the Shaefer furler or just the CDI.
