[Capri25] Capri 25 Boom Gooseneck

[dallas johnson]

I realize I sound like an old geezer when I send these message out, but, well...perhaps I'm an old geezer. 

The C-25 goosenecks typically have a seemingly obvious spot for attaching a shackle to the sail tack on the luff (forward) section of the gooseneck. 

While this seems like the obvious place to attach the tack, it creates compression from the outhaul on the foot of the sail against the gooseneck pivot point. It's bad engineering and it will break eventually (in the middle of a heavy air race).

Instead, attach your tack to the front of your boom just behind (as close as possible to) the gooseneck pivot point. This removes outhaul compression loads from your gooseneck. It won't effect your sail shape significantly and your gooseneck will last forever. If you don't have an attachment point, make one.

I went through several goosenecks until I did this, and that last almost broken gooseneck then lasted six seasons with no wear.

  Travis,


  We've been known to break a few goose-necks too.  I believe the best source for a replacement is Mark Hammett.  He made quite a few, and they're quite a bit sturdier than the originals.


  I'm sure Mark, or someone else on this list, can help you out.


  Thanks,
  OT

    Greetings,


    I have a Capri 25 way out in Salt Lake City.  We have had it for about 1 season.   I was looking through your class thread and wonder if you know anyone there who has replaced the stock boom gooseneck?  Ours is getting tweaked by the hard boom kicker installed by the previous owner.   I would buy another from Catalina direct but it seems like the current one is not up to the job.


    Any thoughts or ideas on who might have tired something else?


    Thanks
