Re: Stus-List V Berth Holding Tank
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. Dave .

Re: Stus-List V Berth Holding Tank
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. Rick Bushie Anchovy, '71 30-1 Tolchester, MD ___ This list is supported by the generous donations of our members.

Re: Stus-List V Berth 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
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).

Re: Stus-List V Berth Holding Tank
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 list. Suggestions of all sorts have come through for forums and Facebook pages. Long story short, we're all happy to be members of such a great community. If you don't like it, we'll be sorry to see you go. - This is Stu's list. He graciously continues to acts as the ADMIN despite no longer owning a C He also pays for the list out of pocket and rarely askes for any contributions. If you feel so moved please give financial support. IIRC Stu had suggested that amongst the 700 list members if everyone paid ~$10 per year it would cover his expenses. You can arrange payment here: http://www.cncphotoalbum.com/chandlery_2/store.php?crn=226 Any other questions or things we can do to make your experience better just let us know.
