Everyone else that replied thanks as well.
I'm going to start doing some measuring and try to make a decision on where to
put it.

OK Collin I put a few pictures of my holding tank and the invoice for it at
https://drive.google.com/drive/folders/0B-NqAxQ6JxFTZ3E3VHc1LURQZEE?usp=sharing.
Let me know if that URL doesn't work for you.
Looks like the PO spent ~$200 on it from http://www.trioniccorp.com. They no
longer list the exact model he ordered but I bet the 2015 would work, and you
might need the custom fitting kit.
Obviously the PO must have had to take apart all that cabinetry to install the
tank, and put it back together afterwards. I'm sure he fabricated that shelf
around the tank. I haven't gotten in there to see how he mounted / supported
the tank on the hull. In the pictures of the tank, the silver hose at left is
the vent, and there is a vent fitting just below the rub rail on the outside of
the hull (see also
https://drive.google.com/open?id=0B-NqAxQ6JxFTY0VBM2hlT0hveDQ). The center
white hose goes to a waste pump-out fitting on the deck. I'm guessing both
those fittings were already there when the PO installed the new tank. The
white hose at right is black water in from the toilet, which loops over from
far right (i.e. forward most).
I also threw in a couple shots of the toilet pump and under-sink plumbing for
completeness. In the picture of the toilet pump, the silver hose is flush
water in to the pump; the white hose on top is flush water out from the pump.
The white hose on the bottom is black water out from the toilet. In the
under-sink shot you can see those same flush water to pump, and black water
from toilet hoses. Plus the fresh-water lines and pump to the sink, and the
drain and through-hull.
The way my washroom is plumbed, I don't have overboard discharge or Y valve or
above-waterline loop etc. And I can flush the head with raw lake water, but I
don't. I always flush it with fresh water from the forward tank. My first
reason for doing that was to keep lake water bacteria and organic matter etc.
out of the system, to reduce odor. But maybe a second advantage is that it
will help the system last longer to use cleaner water. I can also drain the
sink into the lake, but I don't - I generally pump the sink drain water through
the toilet into the holding tank. So I generally keep that through-hull
seacock closed all the time. There was an earlier thread on head plumbing back
in April, if you're interested:
http://cnc-list.com/pipermail/cnc-list_cnc-list.com/2016-April/084241.html
For where I sail (a lake in Colorado with a pump-out station at the marina),
this arrangement works fine. If I was doing extended cruises offshore I'd
probably want overboard discharge and raw-water flush. But for now I don't
need huge holding tank capacity, and I don't like the idea of smelly sloshy
holding tanks right under the pillows in the V berth :)

Hey Randy,
Yea it would be helpful if you knew where he ordered the tank from, if I could
find one that fit well for a good price that would help out a lot.

Hi Collin,
Welcome. If you look at the various 30-1 brochures
(http://www.cncphotoalbum.com/brochures/brochuresndx.htm), it seems C&C may not
have installed a holding tank originally, but began doing it somewhere in the
production run. For example
http://www.cncphotoalbum.com/brochures/30foot/30b2pg02.htm says "Washroom Port
side ... large locker outboard with double sliding doors for toilet articles.
Stowage under". And http://www.cncphotoalbum.com/brochures/30foot/30b3pg04.htm
says "WASHROOM Port side - ... large storage locker with sliding doors" and
"Interior Equipment and Fittings: Marine toilet with retention device for those
areas requiring it". But
http://www.cncphotoalbum.com/brochures/30foot/30b1pg02.htm says "TANKAGE:
Holding: 13 U.S. gallon tank".
I have hull #7, built September 1972. I just bought it in January. My boat
has a holding tank in the washroom on the port side outboard, behind those
sliding doors. The PO advertised "complete new holding tank" as part of work
he did in 2012. I don't know if he installed one in the same place as an old
one, or what. I believe I have the invoice on the boat, showing what he
ordered and where he ordered it from. If you're interested in that, I could
get it next time I'm at the boat and send you a scan of it.
But I would imagine you could install a holding tank in that location, and only
have to deal with removing and replacing (and custom fitting) wood paneling and
trim etc, instead of installing one in the stowage compartment under the port
side of the V berth and having to enlarge the fiberglass opening there and run
the plumbing into there, etc.

Subject: Stus-List V Berth Holding Tank
Hello, This is my first posting to this list. I'm used to forums like on the
Moyer site, so hopefully I'm doing this right.
I have a 1974 C&C 30 MK1. To my knowledge, it was built without a blackwater
holding tank for the Head. At some point over the last 40 years a P.O. put a 5
gallon Jerry can in a storage compartment in the V Berth and installed a Y
valve after the macerator. One side of the Y valve goes overboard the other
goes to the Jerry can.
I'd like to install a legitimate holding tank and I think the storage
compartment on the Port side of the V berth is a good spot.
Here's my question...
The current opening to that storage compartment is very small, just barely fits
the square 5 gallon jerry can. Can I make that opening bigger without
affecting the structural integrity of the boat? I understand that I'll have to
make the hatch sturdy so it won't fall through when you sleep in the v berth.
There is a lot more to do, like install and plumb a pump out deck plate. But
the placement of the holding tank, and finding one seems to be the hardest part.
Thanks for your help,
Collin
