[C38] Keel & Toe Rail

[Steve Smolinske]

When fixing the catalina smile on Peregrine, we started with grinding
the crack down to good material, what we found  was that  it went deeper
than we suspected and once all the paint and filler was ground off.  We
discovered  that the leading edge of the keel at the interface to the
boat had some very large honey combed holes, not in the lead but in the
filler along the leading edge near the stub.  We filled the holes  with
epoxy (a lot of  epoxy) then filled the crack we had ground out and the
surrounding area with long haired bondo, faired  the work, epoxy coated
and painted and two years later still no problems.   Don't be afraid to
take a grinder and sander, after all its only lead and can be filled and
faired pretty easily.

Mark: 
Chuck's solution to the toe rail is very cool. I will use it on my toe
rail.
Last haul out I had weeping from several spots on the keel. The yard
suggested grinding away the spots, filling, then faring them. They said
that the infiltration would spread. I had them do the work; they charged
about 1 boat unit for the job. I am three years into this bottom job,
and the diver does not indicate any problem down there. Of course, next
haul out will reveal all.

	Mark,
	
	The easy one.  
	I fashioned a gouging tool by heating and bending and sharpening
the tip of a narrow bladed screwdriver.  I used that to scrape out the
loose material.  I then took my "roto tool" and ground out a bit more of
the old caulk to obtain a clean surface  at a depth of about 1/4 inch.
I then applied 5200 caulk, using a very narrow tip to ensure complete
filling of the gap.  Smoothing with a wet finger to make it pretty.
	
	Second:
	Looks to me like the material over your lead keel has developed
cracks with some infiltration.  No big deal in terms of your boat
leaking or sinking.  If you are really racing crazy...  you could use
this as an opportunity to re-fare the keel....  or wait until some of
the material either softens or falls off to deal with it.

		Hey All... 

		 

		Two questions for the group. 

		 

		First the easy one... 

		 

		What is the best material to use to fill the outboard
gap between the bottom of the aluminum toerail and hull? (5200? Caulk?
Epoxy?) (Pic attached)

		 

		Second...

		 

		When I bough the boat  3 years ago I noticed that it had
some strange leakage / seepage at the bottom of the keel. The surveyor
wasn't concerned (and didnt have any explanation), as the keel seemed to
be solid... and honestly I wasnt too concerned because the bilge has
always been pretty dry, it's way low on the keel, it's underwater and
with a good coat of paint out-of-sigh-out-mind. But, I've always
wondered what the heck is going on here. More than a few boatyard
conversations havent turned up much, so I thought I'd kick it out to the
group...  See the attached images... Any ides?
