One thing I found on our new (last fall) boat that was missed by the survey was some crevice corrosion on a couple keel bolts under the nuts.
The surveyor tapped on each bolt, listening for dead sounds, and they did sound fine. But, he did not remove the nuts...not sure if that's s.o.p.
The bilge had water in it, and I suspect had for quite a while. That apparently didn't raise a flag with him. I think he did a fine job...but...
Since then, I took each nut off (one at a time), and the 3 most aft had some cc. I will need to take steps...but they are still strong now. I cleaned the bilge, bolts & nuts and coated them with Lanacote. The sealant around the bolts is still fine (keel not leaking)...so...I have re-torqued the nuts. I'll need to do the fairly common keel bolt fix sometime soon, though.
So, if the bilge has water in it...and the surveyor doesn't mention it...you might want to ask about cc on the bolts.
It's not whether you're paranoid...it's whether you're paranoid enough.
