The Catalina 27 is a great boat. We've had a C22, C25 and now our C34, kinda "skipping" the C27 & C30 sizes!
But they are all similar in build and good quality.
The older C27s had a chainplate issue. Catalina Direct:
has replacement chainplates, which replace the U bolts with bar stock backing plates
. This is VERY important for rig integrity.
Otherwise, no different than any other boat:

If it's an inboard, beware of limited access to the stuffing box and the rw cooled engines usually employed. If it's a freshwater cooled engine
(i.e., HX), then check on the alternator
bracket upgrade. If it is an M25 engine
, our C34 website has a ton of information about them.
