I am replacing the holding tank in my 1984 Hunter 37c. I've read the archive information, but I didn't see anything regarding an idea I came up with. What do you all think about using the bow locker (the locker most forward in the hull of the boat)as a holding tank? Not placing a holding tank in the locker, but using the locker itself (the interior of the boats hull) as a holding tank. It could easily be made a watertight compartment by replacing the wooden hatch board with a watertight hatch, gaining not only a holding tank but the safety feature of a watertight compartment. It has adequate capacity and because of its location is relatively impractical to use for anything else. I would appreciate the group’s thoughts. Secondly, I saw only one posting regarding "Air Heads," the system that uses composting for solid waste treatment. The system eliminates thru hulls, plumbing, hoses, valves and holding tanks. It seems incredibly, elegantly simple. Does anyone have any experience with this type of MSD? Thanks for you input. tj/ Itchen/ Tacoma, WA

I think that's your chain locker...
If you turn it into a holding tank--which is a bad idea anyway--where will you store your anchor rode? Why is it a bad idea? All integral tankage is risky...'cuz anything that can happen to the outside of a hull--blisters, water absorption/rot etc--can also happen to the inside of the tank...and because it starts from the inside, you won't know it till it becomes serious enough to be obvious on the outside of the tank. What's more, turning any storage locker into a waste tank or fuel tank means that it can never be turned back into a storage locker. You aren't likely to be the last owner of your boat...technology changes...future owners have other ideas about how they want to use the space, etc...but you've cut off all the options. As for the AirHead...It can be a viable alternative to a holding tank if you're in "no discharge" waters, but I can't see any reason to store waste aboard in any form if you don't have to. The discharge of treated waste is legal in 90% of coastal waters...it can be flushed directly overboard at sea...why store it aboard? In a holding tank, 90% of the volume is flush water...the Airhead doesn't use any. Instead, it separates urine from solids. The solids dry out, but the urine can't go overboard inside the "3 mile limit" (which, btw is just about everywhere in the San Juans except the strait)...so it it has to be stored separately from the solids, either in jugs or a tank. No flush water means neither fills up as fast, but if you have to carry jugs of urine ashore and dump 'em, I don't see the advantage over a portapotty...if you have to deal with a tank, you gain nothing over maintaining any holding tank except it can be a much smaller tank. It MUST have power to run the fan 24/7/365...which makes it problematic for a boat on a mooring. Your waters are NOT "no discharge"...the discharge of treated waste (waste from CG certified Type I MSD--device that treats waste and discharges it overboard legally in all waters except those specifically designated "no discharge"). If it were my boat, I'd install a Raritan ElectraScan or PuraSan http://www.raritaneng.com/products/waste_treatment/index.html They treat and discharge each flush, so you never have to store any waste aboard...only need power after a flush...don't use any at sea beyond the "3 mile limit" where it can be bypassed (the Airhead cannot be)...no urine jugs to mess with...and every bit as enviromentally friendly as the Airhead. And about the same price. All that said, the people who have installed the Airhead claim to love it. You might too.

air head
tj: I put an "airhead" in H37C about a year ago. It onbly gets occasional weekend use, but so far its a big improvement in the way the boat smells. We had a 5gal holding tank under the stbd side of the V-berth, so pump-outs were frequent, unpleasant, annoying, and I usually had to take apart the Jabsco macerator pump every other time. Tjere are only two of us, so the system is not overloaded. I haven't dumped the composting bin yet. The literature ays it hs a capacity of 80 "deposits" before it fills up. The "liquid" tank is another mater, especially if your female crew are beer-drinkers, but it's a simple matter to dump the small liquid tank. I may plumb that tank into the existing holding tank which I believe would be OK to pump overboard. It's an elegant and more sanitary solution than a holding tank, and that opinion is rendered by a Ph.D. microbiologist (me). The 24/7 fan is 100ma and my solar panel more than keeps up with that minimal draw. Lectra-San Shmectra-San IMHO. RS

TJ that would be a long hose run
to the forward locker. The beauty of the orignal tank location was its proximity to the toilet. I have same boat and when my aluminum tank fails I will proably go with the Lectrasan in the old tank location. In the meantime, I have moved the deck pump out to the starboard side behind the shower so the hose connects right at the outlet of the tank and I took out the vented loop that run up/down in the hanging locker, since the overboard valve is always closed. If I go with the Lectrasan I will run the vented loop up behind the shower.

Sorry, Richard, but it's NOT legal to pump urine
overboard inside the "3 mile limit." US marine sanitation laws don't distingish between urine and solid waste...it's illegal to discharge ("discharge is defined in the CFR as "includes, but is not limited to, any spilling, leaking, pouring, pumping, emitting, emptying or dumping") ALL "human body wastes and the wastes from toilets and other receptacles intended to receive or retain body waste." Which makes it illegal to pour your urine jugs over the side or dump a tank--even if it only contains urine--unless you're in open ocean at least 3 miles from the nearest point on the whole US coastline...which for you would be at least 3 miles out in the Gulf from the mouth of Mobile Bay.

thanks for the input
Thanks for the replies guys ... it helped me make a decision. I'm going to go with the Airhead for the following reasons; I don't have to hassle with installing a new tank, hoses etc. and all the headaches that beckons; sanitation (I rather carry a gallon of compost than 20 gallons of raw sewage); simpler system - nothing to break or leak (head, pumps, thru hulls, valves, hoses, connections); simpler maintenance (add peat-stir-empty, add peat-stir-empty); greater holding capacity (holds solid waste for two adults for a month); the (fan) power usage is negligible (.08mA) and can be completely circumvented with a inexpensive solar cell; convenience - if I don't dump urine every couple of days, I can carry a five gallon jug for extended storage, (after all the 50 gallons of diesel I carry is far more toxic than any urine) - I also think dumping a five gallon jug is a lot easier than pulling up to the pump-out and, through the course of pumping out, spraying myself with raw sewage (which I've done). I was intrigued by the Lectra San, but was more concerned by the reliability and less concerned by the power usage (50 amps). Guys who repair MSD’s have told me, the maintenance on Lectra Sans is frequent if they are not used routinely as the plate’s cake up and fail to perform their bactericidal function. I’ve also heard that there was an effort by the USCG to eliminate them because of the maintenance issue and the systems ability to bypass and pump overboard. Peggy thanks for your input. I had thought about damage that could be done but the tank I removed was made of fiberglass and there have been numerous comments in the archives about fabricating custom FG tanks. The very forward locker on the Hunter 37c is not a chain locker, some have converted it to that, but it is originally just another empty locker in a terribly inconvenient place. Lastly, I figured that some place on the boat must be dedicated to a holding tank. At least by using an arguable useless locker as one, I gained a safety feature in a watertight space and I had created a tank space that is accessible for cleaning and/or repairing. I'm not sure I agree that the space cannot be recaptured; with an impervious coating applied to FG hull the space could be easily sanitized with a bleach solution. Scott I think that’s a great idea on moving the deck plate to the starboard side. It certainly cleans up the port locker (I never liked that vented loop in there with clothing, plus it took up so much room). You won’t risk siphoning on a port tack will you? Richard thanks for you input. It's good to hear from someone who has first hand experience, especially where is hot and humid. How ... where did you place your airhead? Its footprint is somewhat larger than the space allowed by the boat. Thanks again everybody … tj

Lock me up
TJ: I had to make a "step" out of wood which serves as a base for the liquid tank. The main base of the AH fits OK on the old footprint. I'm going to get the plumbing to run the liquids into the old holding tank. With regard to urine: Before autoclaves, early microbiologists used fresh human urine to culture bacteria. It is sterile as it comes from the tap (unless you have an infection). There are religious sects in India who regularly drink their own urine without ill effects. Before God and the powers who rule the earth I admit to having peed in the ocean. I further resolve to continue to pee in the ocean. As a card-carrying microbiologist I can assure the general public that my few liters of pee do no harm whatsoever to the environment. BY adding my sterile urine to Mobile bay I actually REDUCE (however infinitesmally small) the CFU's/mL of fecal coliforms which pour into the bay from all the municipalities upstream. If forced to I'll drink my urine. Will you drink the outflow of your LectraSan? RS

airhead footprin
Thanks Richard, I thought about extending the original commode base. I also thought about just reversing the shower and commode space; i.e. putting the airhead in the shower and then using the old commode space for a shower. I need to cover the wood and the locker in there, but I think a wrap around shower curtain would suffice. I'd have a lot more room to shower ... I could maybe even include the wife. Any thoughts? Of course this now begs the question, what are the ramification of peeing in the shower ... we're just having fun at the CG and EPA's expense right?
thanks again guys ... tj

Seems like too much expense and work for such a simple problem. I guess if you can legally pump overboard maybe the ideas make sense. But the v-berth locker(big one) can easily accomodate a 30 gal. tank and still provide a lot of storage(I have four transducers in there that have to be accessible). I have a 22 gal. tank with good Sealand hoses and have zero odors and plenty of capacity. The trick is to not use gallons of water on every flush. We clear the bowl and then clear the hoses as the last thing in the evening. And my Raritan Cricket head seems bulletproof. Six seasons and never a problem. I am sure that fresh water makes a difference here. Maybe pumpout is a problem where you are? We don't seem to have that problem in our neck of the Great Lakes. And I do use the forward locker as a chain locker with a hawse pipe leading into it.

forward locker
Right Ed ... I saw your photos in the archives of both your chain locker and holding tank installation. I think you did a nice job on both. At one point, after seeing your example, I was thinking of going the way you did. I even made a cardboard template of a holding tank for the aft v berth locker (the same one you used). I like the size and shape of the tank, but it would still require a sizeable amount of locker modification, tank installation and fiberglass work to install the tank, route the hoses, etc., not to mention the cost of each item. Speaking of cost … the cost of the composting head is $900.00 (complete system). Installation requires bolting the head down, route a vent hose and two wires for the fan. That's it ... unless you want to include the cost of a gallon bag of peat moss every month of so. I don't understand the argument in comparing the composting head cost, to the cost and hassle's of installing a conventional MSD (toilet, hoses, tank, etc.), tank treatment chemicals, pumping out (either overboard or at a pump out station), the potential for flooding your boat, clogged hoses, leaking tanks and so on. I don't get it? How is a conventional MSD simpler and less expensive than a composting toilet? In the beginning I was unsure of composting system, but after discussing this with you guys, I'm convinced it's the way to go. Below are the conclusions I reached after reading your comments; 1) A holding tank is emptied weekly or more frequently (for liveaboards); A composting head is emptied once a month (that's a no brainer). 2) Carrying and emptying a porta-pottie or pumping out (either overboard or at a pump out station) is far more hassle than carrying and emptying a gallon jug of urine (weekly) or a gallon bag of compost (monthly). 3) We all at some point carry and store human waste on board our boats. It's more sound environmentally (and I don't consider myself an environmentalist) to dump compost (treated sewage) overboard (where legal) than to discharge untreated sewage overboard; again, holding tanks (in no dumping zones) are emptied into the city sewer system (via the marina pump out) which can, will and have leaked or ruptured dumping millions of gallons of untreated sewage into our ... habitat. Composting is merely recycling (and that's a good thing ... right)? 4) Composters carry far less volume and weight than a holding tank. An entire months compost doesn't weigh as much as just a small holding tank (let alone it's contents), nor does it take up the valuable storage space. 5) There is a lot of repair/replacement information in the archives about holding tanks, construction, materials, location, positioning, hose adaptation, toilet types, macerators, power needs, but I see nothing about the repair/replacement of a composters ... not even on the web (how can I argue with a system that has nothing to break?) 6) The power usage for Lectra Sans, Macerators, Vacu-flushes, electric overboard pump outs is hundreds of times greater than the .08mA the composting fan draws. All of the afore mentioned require sizeable battery banks, except the composter. The composter can run on a small, inexpensive solar cell. The composting fan is not even required. What is required is a ventilation of the compost; if that can be achieved without a fan, then no power at all would be required. 7) Composting never requires pumping out ... ever. (How cool is that?) Well! Don’t I sound like a born-again composter? later guys (I enjoy the discussions) tj

How far does the urine tank protrude?
I checked out the Air Head site, and it looks like a great alternative to porta-pots, but the urine tank looks like it protrudes a long way out. Can guys stand close enough to use it without making a mess, or do we have to take a seat like the ladies do to avoid "spillage"? I put a portapotti on my H25 with a large holding tank so I wouldn't have to empty it so often. Bad idea! The tank is wider than the doorway, so I have to turn that heavy, nasty, dripping tank on edge to get it out into the main cabin and up the companionway and out onto the dock. I've been planning to install it permanently & add the topside pump-out on it, but the Air Head looks like a better way to go IF there is room in my boat for it. The urine tank might also jut out far enough to hamper passage into the v-berth. Any suggestions?

vents and follow ups
Rich ... I thought about using the head vent, just not sure though. I thought you might have drilled a hole somewhere. I'm still waiting for the Airhead to arrive to see how it would actually look. I'll give your suggestion a shot ... thanks again/tj Del Rio ... the airhead is portable (kind of). You could almost put it anywhere. Have a quick disconnect vent hose and wire for the fan and you should be in good shape. Scott .. You're absolutely right of course ... but then why have a siphon at all? Where did you catch that Halibut (Southeast or Neah Bay)?

To Bad Lectrasans aren't legal anymore either.
Lectrasan, now there's a novel idea. A compact waste treatment system onboard. Too bad it isn't legal anymore, that is the direction I was going to go in when my flexible tank crapped out on me. Pun intended. The potty police are everywhere nowadays, best to keep it clean and install a 500 gallon holding tank and visit the pump out station regularly. Look out! the potty police are coming after Composters next. I expect that they will be made illegal sometime in 08. *grr
