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

Subject: [IC27A] Foam Core Construction

  
Hi All,

You should all be aware the foam core construction in the modern world is
relatively common and a strength weight ratio plus in sail boat
construction. 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.
