Over and beyond the Q of core vs noncore hulls---I have a question regarding the head's drain port into the bilge----I have a 88 C 27 tall rig---the drain port in the head that I assume drains into the bilge does not work (drain)----I had a similar problem with the anchor locker and was able to correct it (the drain hose was kinked)---was able to take off the front panel in the V berth area and change the drain hose---I am assuming that the head drain hose has a similar problem but I do not know how to get at this hose---has anyone had a similar problem and if so how was it corrected-----the deck (floor) appears to be one solid form fitted piece and I have tried "rodding" and using a pressure hose from both sides of the hose w/o success----any advise would be appreciated

Catalina has used a foam core mat in various above the waterline locations. I have certainly found it on my C270 and Catalina also now uses a solid aluminum core in some locations so hardware can be bolted into it rather than use the old school through bolted scheme. Getting back to the origin of this thread, the hulls of Catalina's closed cabin sailboats are solid hand laid fiberglass with the exception of specific areas that need special reinforcement. The floor of your keel stubs, unless reworked after construction (i.e. Judy's) is cored with plywood. Newer designs like the C270 have a structural grid attached to the inside of the hull while some hulls have foam beams placed and glassed over as hull stiffeners. In the case of the stiffeners the foam is merely a form for a hand laid fiberglass structure and remains in place. I've added the Sail Magazine Catalina Factory Tour article to the files section which describes shows hull construction.
