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. Best Regards, Randy Stafford S/V Grenadine C&C 30-1 #7 Ken Caryl, CO ----- Original Message ----- From: "Collin Ferguson via CnC-List" <cnc-list@cnc-list.com> To: "cnc-list" <cnc-list@cnc-list.com> Cc: "Collin Ferguson" <cferg...@yahoo.com> Sent: Tuesday, October 11, 2016 5:49:16 PM 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.
