Bill:
You will get different advice on this issue, as you have noticed.
I am no expert, but:
1. there should not be cracks in the bilge sump between the keel bolts,
and
2. if there are cracks there, and you are quite confident that they are
leaking water, get it checked out by a knowledgeable person.
Years back (1991), a friend bought a 1985 C&C 33 MKII in near new
condition. That Spring we were removing the antifouling paint and
discovered a hairline crack around the front of the keel on the keel
stub, not the keel joint where we experience the C&C smile between the
keel stub and the keel. Question now was, it is just a surface crack?
How deep did it go into the hull?
Owner hired a guy to address the issue. He ground out the crack and it
almost went through the entire hull before he reached dry
material.....it was seriously deep The previous owner had a hard
grounding during Chester Race Week and did not tell my friend about it
when he sold the boat. It was a significant crack and we were glad we
found it and addressed it before we took the boat to Boston that Summer
to do the Marblehead Race.
Your call, but I would have someone experienced in these matters put my
mind at rest.

Thanks for the info, when I am on the hard next I will try this.
I am certain is it coming from the small cracks from visual observations.
I wonder if Wally would like to leave the sunny south and make a trip
up to the frozen north for a little hull repair work ;-)
Cheers,
Bill

1/2 cup per day is not really much water ingress...on my 35MKII water
does come down the mast when it rains and accumulates under the mast
step...it can move slowly show into the bilge...are you certain that
is not the source of the 1/2 cup per day...If you have an issue with
water getting in from below it should show up when the boat is on the
hard...fill the bilge with water and it should leak out and maybe let
you know where the source of the leak is...grind that area out both
sides at the keel hull joint and dry well...then squeeze in some
polyurethane sealant , let that cure well...cover with epoxy putty
and finally with resin soaked chopped strand glass matt...what you
describe does not sound that serious to me so I don't think you would
need to do a major repair...but if you have the extra cash separate
the keel afrom the hull and do like Wally did on his Landfall
38...that job was probably better than when it came from the factory

I did shop-vac the bilge and wipe it dry. The water influx was
slow - about 1/2 cup per day at most. But that was at the dock,
sailing hard the influx might be more, i will check when I go out
next. I think there has been some contact between the keel ad
something hard in its past life but not too sure how hard and
what repairs were done. The cracks are not in the keel structure
as it is very strong but in the sump area between the bolts. I
doubt the cracks extend directly to the outside hull. The leaks
are probably from the C&C smile to the hull-keel interface.
I am bobing about on a 750'x137' drillship watching a cold front
pass by - we are getting 30knt sustained outside, sea's don't
look too bad from 80' up - maybe 10-14'. check out:

Currently working on C&C 34 with the famous keel smile.
Previously repaired by boat shop a few years back and has returned.
After haul out I cleaned out seem filled with 4200 ,torque bolts
to 300 ft. lbs and then covered with 2 layer matt , 2 layers
cloth another matt and final layer of cloth using West System.
Each layer was a bit wider starting at 1 in.and ending around 5
in..Inter protect in spring as weather is now going downhill.
Will know if it works after haul out next year.
Minimal cost so worth the try.

I have to agree. I had a small leak in my bilge two summers
ago that strangely enough didn't go away by itself and got
worse this past summer. The PO had told me about a hard
grounding.
I got it surveyed this fall after haul-out by a surveyor
with lots of C&C experience. Turns out I have hidden
grounding damage. I re-launched on Friday and sailed over
to Bristol Marine in Port Credit on Sunday. Will be $$.
At least I had a great sail yesterday...I had all Lake
Ontario to myself.

Yes - having cracks through the bottom of the boat is not a
trivial thing to fix. A friends boat had an issue like this
that was repaired in a quickie put-epoxy-on-it manner and it
opened up while he was out. That trip was not fun :(
His crack was above the keel, so we could get at it with the
keel on. We ground it out and added layers of glass and
epoxy outside and then did the same on the inside. I can't
say it is perfect, but it is about 500 times stronger than
the last "repair". Also you might want to make SURE that is
where the water coming from. I would shop vac and towel dry
the bilge and watch it very carefully. The 35 MK I and II
keel structure is pretty strong and I would say cracks
through the boat aren't common.

Bill:
I would tend to agree with Jim Watts.....have someone
knowledgeable inspect your boat. It is not normal to have
cracks in the sump that are leaking water.
I would not simply cover up the cracks without knowing how
significant they are.
Did your boat experience a 'hard grounding'?

I blasted out to Victoria to escape the frigid Alberta cold
for a week or so. So I thought a little biking and messing
around in the bilge would be fun. The water in the bilge was
a bit salty and the mild steel plates below the keel bolts
were badly corroded so I replaced some of the plates with
some 3/8" 316SS. I cleaned out the bilge and watched. When I
removed the bolts, one at a time :-) there was no seepage
around the bolts - a good sign I think. However there are
some cracks in the sump area between the keel bolts and
these are seeping water at about 100ml/day. I didn't go out
for a sail so assume there would be more water ingress when
the keel is under some stress. Is there some way to seal
these cracks without dropping the keel? What is the
thickness from the bottom of the bilge to the top of the
keel stub? Can I just pour some epoxy in the the sump area?
Thanks!!
