Keel Mount Bolts in Bilge

I have recently purchased a 27', tall rig. It is a 1980 hull. Upon cleaning out the bilge for inspection I notice several fine cracks parallel with the keel adjacent to the keel bolts. There is also a crack externally on the leading edge of the keel where the keel mounts to the hull extending back approximately 12" on either side. Could this crack be the result of a hard aground? I don't know much about the history of the boat except the last owner (2nd. owner) knew little about proper boat maintenance. I assume the keel bolts need to be inspected and the wood in the keel mount possibly needs to be replaced and the bolts re-torqued. Has anyone had a similar experience? The bolts on my keel appear to be stainless.

see C27 web site

SAee the web site and read about keel bolts. Somewhere in there, they changed from iron to stainless steel, but if you have the earlier ones, they had problems which are fully explained on the web site. The "crack" you described is also explained on the web site. Usually, but not always, caused by improper blocking of the keel when stored. Keel has an angle to it. If the block the keel rests on is not similarly angled, all the weight rests on the trailing edge, which in turn puts a lot of pressure on the forward top edge and leading keel bolt. Pulls the whole thing away from the keel. Easy fix, described on the C27 site. Tom Monroe Carlyle Lake

what is this C27 website?

Can you please provide a link to the website? If its www.catalina27.org I can tell you there is very little info to be had there, unless I am reading it wrong.

whoops ...

They changed the site!! Sorry. There used to be a tech forum section where you could look such things up. Might find it in the archives here too, but ... The external crack you describe could come from a grounding, but I think it's more likely it resulted from improperly blocking the keel when the boat was stored out of water. The bottom of the keel has an angle to it, and if the block the keel sits on does not have the same angle, all the weight is focused on the aft edge. This in turn puts a lot of stress on the forward keel bolts, and the keel can pull away from the hull a little bit, resulting in the crack you describe. Again, could also be grounding, but I don't think so. To fix ... Block the boat properly, with the right angle distributing the weight. Torque the keel bolts. Can't remember the spec, but you can get it from Catalina Direct or Catalina Yachts. Then you can prep the hull/keel surfaces, epoxy and barrier coat, and you're back in business. While everything's nice and dry in the bilge, you can also do a gelcoat repair on the little cracks you mentioned. Lots of C27's have them. Mine did, I fixed per above, doesn't seem to be a structural issue. (I'm assuming you have the nice new stainless steel keel bolts and that they are in good condition. If you have the old iron onees, they'll be real rusted. You'll need to talk with Catalina. They have a procedure where you encapsulate the iron ones in epoxy and install some stainless steel lag bolts. You need to follow their directions and procedures.) Sorry about the web site.
