Hi,

I have a C-25 in the California Delta. Last weekend, I went out there and found the tang at the back of the boom had sheared off! I found a new tang at Catalina Direct, but I can't seem to be able to remove the screw holding the tang on there.

Has anyone else had this problem and solved it?

Is the screw tight or simply spinning? You may have better luck removing the boom end cap and extracting the screw that way.

Mine was loose, I always assumed there was a nylok nut on the other side but I never removed the end cap to find out.

There is a nut on the other end...mine had started to come loose and the bolt was just free spinning and appeared that it wasn't attached to anything. I removed the end cap and there was a nut fairly well seated in a long bolt. There was no danger, but I imagine if that bolt unraveled enough, the pressure could sheer it off. I just tightened it up to the point where there was still enough room for the attachment to pivot and closed up the boom.

I've long ago stopped using the tang for the mainsheet. I did not like the single bolt holding that load. Though I know it does because it's on every Catalina I see. I through bolted a regular bail to the end of the boom. Just seems better. I do use the tang for attaching to the pigtail on the aft stay.

Interesting Mark, did go through just boom or were you able to "catch" the end cap casting?
I believe the end bolted tang spreads it's load through the end cap casting which would in turn spreads that load around the boom extrusion.
The Catalina rigging is deceptively well designed.
That said, I am exactly the kind of guy who would do what you did. In fact I have several new bails in my SS bin that I bought because they were nice hardware, hmmm hardware.

Well, mostly have it off. Had to remove the end cap, there is a bolt, size 14mm, that was difficult to get off (thank goodness for impact drivers). Even removing the endcap screws required some drilling.

So now the bolt is off, but I still can't remove the screw due to corrosion. Back to the shop!

Frank,
I did capture the end cap. I pulled it off to see what was what, then drilled through about 1 inch forward of cap end.

I too have a hardware fetish...SS jewelry for the boat
