[C38] The Catalina Smile

Glenn,

Attached is a Catalina factory sketch depicting the smile and repair.  If you haven't observed the "smile" your yard must be supporting the keel correctly.

Cheers, Steve

  Hi,

  I have a 1983 build that I believe is in the production run that has the smile.  My boat does not have it.  Could someone give me a description or a picture of it.  I am starting to get worried.

  Regards,

  G!enn

I wouldn't take the chance.  Greater support at the aft end will cause a 
moment (rotation) on the keel which could put the forward end into tension 
causing the crack to open up.

  Why wouldn't you ask the yard to support the keep along most of its
length?

Our boat is an '85 and is in So Cal- no  winters.  The purchasing survey
in
'97 did not show a smile and two years later a smile appeared after haul
out at which I was clueless as to the proper method of "on the hard
support".
The cradle was ok , but the keel was supported near the aft end. The
yard said all Catalina's have that smile- don't worry about it.  Two
years later at the haul out the smile grew and some of the fiberglass
and fairing material at the smile was literally rotten and smelled
rotten.  The smile ran halfway back along the keel stub.  We made about
5-8 templates, ground out the complete stub to keel mating profile all
the way around exposing bare lead.  The grinding was tapered from the
mating profile a good 3-4 inches up and down.  I don't remember exactly
the depth of material that was removed at the joint, but it was
considerable- 1/4 to 1/2 inch.  It took considerable amount of heat to
dry area, before new material could be applied.  The rotten material
removed was a combination of fiberglass and fairing material.  When the
mating surface was dry, we caulked any gaps with epoxie and glass. The
new material was layer after layer of  glass cloth and West System
epoxie- The last few coats was epoxie thickened with silica.
Applied the templates and sand to original faired surface.  The job took
4-5 days.  The smile repair was done six years ago and has not
reappeared.  But when the boat is hauled now, I am telling the yard
exactly where to put the keel support- as far forward as possible with
no supports at the aft portion of the keel.

    Catalina says the infamous "smile" many of us have discovered on our
boats is due to improper positioning on our cradles when the boat is
      out
    of the water.  I have fixed (by grinding, filling, gelcoating and
painting) my smile three times before yearly spring launching.... only
to have it be there when I haul the boat in the fall.  This does not
rule out what Catalina says as it could be the keel stabilizing after
      a
    winter of compression.  I do know it is not due to loose keel bolts as
      I
    have routinely gone through the rather difficult process of tightening
(never found a loose one).  I also know the smile appears on other
Catalina models as I have seen it many times here in the north where
      we
    all have to haul for the winter.
Regarding repairs on the smile.  While I have done this three times
      and
    will probably continue, I do wonder if I am sealing moisture into the
repair and if this is causing even more of a problem when it freezes.
Any comments?

I've been trying to further research this fix without too much
success. Perhaps you all can help.

Is procedure recommended for all Catalina 38s, or is it only
recommended when a boat exhibits symptoms?

If so, what are the symptoms? The "catalina smile"? Others?

Who has had the fix done to their boat? Has anyone done it
themselves? Any advice or cautions? Did the procedure correct the
problem?

Thanks!
