That is a bit low for a "Catalina Smile". The typical crack in Catalina
fins is up close to the stub and is caused by impropper support of the
heel of the keel while it is on a trailer. That looks more like plane
old delamination after a bump on a rock. Without knowing what condition
the cast iron is in under the glass it is hard to say exactly but more
than likely you just need to grind out the crack to bright metal,
feather the edge back into sound glass and build it back up with
glass/epoxy. Be prepared to grind back a good ways as once water gets
to the iron the rust keeps delaminating the glass and spreading.

Here is a site with some drawings and other details on Catalina keel
repairs. http://www.blumhorst.com/catalina27/...tory_drawings/

The link below has some pictures of a 1977 Catalina 27. I was hoping
someone might comment on the damage to the keel ... i.e. how serious
and cost of repair. Any other comments would be appreciated as well
(I am looking to buy this boat).
