the hull (see also

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

Welcome.
Your 5 gallon can reminds me how handy it was at times to have a portapotti
that could be easily emptied in a shore-toilet.
Not sure where you are located but there is a shop in Whitby ON - a
division of MAS plastics - that makes custom poly holding tanks.   In any
case I would make a cardboard mock up before ordering anything.
Ordering and shipping something that bulky across the border would be
killer, twice would be worse.
If you can, have the pump out hose exit from the top, with a length of pipe
reaching to the bottom.  This prevents black water from collecting in the
hose, and moves the fitting/hole to above the (black) waterline.
Not familiar with your boat , but it seems strange you have no deck plate.
IF you are going to cut open any bulkhead, remember to cut the corners with
a large radius to avoid stress concentrations.

Collin,

Anchovy had a 2 gallon gas can for a holding tank when I got her.  I
converted the forward potable water tank into a holding tank and installed
13 gallon bladders in the spaces you describe under the port and starboard
v-berth.

I cut out rather large openings on the two sides to facilitate installing
the bladders and converting the tank.  Then I cut "Flanges" out of plywood
that are epoxied and screwed in place under the v-berth platform.  These
flanges are very strong and allowed me to reinstall the cutouts after the
mods were done.  The cutouts are screwed back in place but not epoxied so
that I can pull them again if needed.

I also removed the overboard through-hull and glassed it in.

I really like having a 30-35 gallon holding tank.

HI Collin!

welcome!  I would contact Holland marine.  This guy is a C 
specialist.  http://www.hollandmarine.com/


He carries a holding tank that he claims; "These tanks were used on many 
Canadian built boats, such as Most C Yachts, Northerns, Viking 33, and 
many other boats"


It ain't cheap but if it works...!
Another option is to get a hold of the catalog from the 
http://www.ronco-plastics.com/ site and try and pick out one that will 
work best for your space.  Most boat tanks are odd shapes to fit better 
against the hull and give you as much holding volume as possible.  As 
you study the catalog you'll start to get an idea of a good shape for 
your anticipated space.


You could actually bring the catalog to the boat, while looking in the 
space you have and measuring.  Get as close as you can with maybe a few 
options and then, perhaps, build cardboard mock ups ans see which ones 
fit best...


Its a lot of up front work and research but, it'll get you the right 
tank.  This is not a short term project.  these tanks last for many 
years, MANY years.  You can also have them place the inlets, outlets and 
ports to your specified locations.


Hope this helps some.

Re: Stus-List V Berth Holding Tank

2016-10-12 Thread Gary Nylander via CnC-List
The later30-1’s have a holding tank directly behind the toilet, in the 
compartment under the sliding plastic doors. Factory item, looks like it was 
built in, with a Y valve under the sink going to a thru hull, also under the 
sink, and diverting to the holding tank. Pump out fitting is on the deck by the 
port. There is an access port to the tank on the ‘floor’ of the cabinet behind 
the doors.

 

It may be easier to put a pre-fab tank or a flex tank like Jake says in the 
area you are thinking about by inserting it through the large center opening in 
the vee berth and run the plumbing up forward on the port side. To do a tank 
where mine is would require some creative cabinetry and a custom built tank (it 
tapers to match the side of the boat).

Welcome to the list!  It seems like you're doing it right.

Just a couple of pointers:
- If you have selected the digest option and you receive the list digests,
DO NOT reply to them.
- Try to trim the message tails to minimize the message size.
-Many email clients organize emails according according to their subject in
what is sometimes called conversation view.  Change the subject to start a
new discussion or if the discussion has shifted.  Don't change the subject
if you want to keep people engaged.
- Some people have complained about the quantity of emails clogging up
their inbox.  Most email clients have the ability to set rules so that any
incoming email from cnc-list@cnc-list.com gets redirected to a separate
folder instead of the inbox.  You can turn the incoming mail notifications
on/off for this separate folder.
- You can search the list with a Google phrase: "site: cnc-list" and then
add your search criteria.  Or by going to:
http://cnc-list.com/pipermail/cnc-list_cnc-list.com/
- Use Picasa, Photo Bucket, Google Drive,  or similar to upload any photos
or files and then share a hyperlink in your email.  Trying to get your
photos below the size threshold is a challenge and besides it just uses
more bandwidth that Stu has to pay for.
- We've all developed a friendly closing by which we state our name, vessel
name, make, model, and hailing port.
- Numerous people over the years have questioned the idea of an email

Hi Collin, 

Welcome. If you look at the various 30-1 brochures (

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

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 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
