Buying a boat without using a professionally certified surveyor is a classic 
mistake.  We require buyers who insist on proceeding without a survey a 
document showing that we strongly advise against it and they hold us harmless.

Subject: Re: Stus-List [C&C 38 Mk 3] Cracks on the keel

Thank you, Dennis, for the thorough explanation.

I had come across the "C&C smile" in the list. My first instinct was that it's 
related. When I see the close-up photos of your 35-1, I can recognize it's the 
same kind of crack (same general width and depth).

However, the cracks have different shapes. The cracks of your 35-1 are only 
present at the front of the keel, and they are at an angle, actually resembling 
a smile. The cracks on the 38-3 I visited are perfectly horizontal and extend 
all along the keel. Does your 35-1 have a deep bilge, like the 38-3 I visited? 
If it doesn't, that would explain the difference.

As for the washers, they are present under the bolt nuts. Visually, they do not 
seem degraded to me. But I'm not confident that a problem is always visually 
detectable. One of the items in the album I linked originally is a video. The 
camera gets quite close to the bolts. Here's the link again:

Thank you,

Probably a simple case of the "C&C smile".  This has been discussed ad nauseum 
on this list.  Many of us on this list have experienced it and repaired it.

In its most frequent occurrence, properly torquing the keel bolts and epoxying 
a couple layers of glass tape over it will fix it.  Here's some pics of the 
smile on my 35-1:

That smile was fixed by torquing the keel bolts, digging out some crumbly stuff 
at the hull/keel interface, filling the dug out areas with epoxy glass, 
layering 4 inch biaxial tape over the hull/keel joint, fairing and painting.  
20 years and 14,000 nautical miles of sailing in all conditions later, it has 
not recurred.

Many of us on the list have similar experience with the smile.

Very infrequently, more action is required.  This involves dropping the keel 
and resealing the joint.  There may be a void or two or a structural weakness 
around one or more of the keel bolts.  Again, this has only been observed 
infrequently.  There are folks on this list that have experience with that.

Again, the most common occurrence is fixed by properly torquing the bolts.  
Here's a link to the torque specs posted on the C&C site:  
http://www.cncphotoalbum.com/doityourself/torquebolts/torquebolts.htm

It was hard to tell in your pics, what is under the keel bolt nuts?  Another 
critical piece of fixing the smile is stainless washers or plates under the 
nuts.  Many  early C&C's had steel plates which degraded allowing the keel 
bolts to become loose.

Hi all,

I'm considering buying a C&C 38 Mk3, but I've noticed something on the keel 
that worries me.

There is a horizontal crack on both sides of the keel. The cracks stretch 
almost the full length of the keel. It's present at the same depth on both 
sides, but it's more noticeable starboard. (see drawing)

The cracks are at the same depth as the keel bolts in the bilge (see photo). 
The keel bolts seem to be all in good condition.

The crack is approx 43 cm (17 inch) lower than the base of the belly of the 
hull, measured from the outside.

Drawing, and photo&video of the bilge here:

By the way, this C&C 38 has the wing keel option.

Have you seen something like this before?
Do you think this is superficial, or structural?
In your opinion, is it a deal-breaker for the purchase?

Any opinion, comment and advise is greatly appreciated.

Olivier
