small boat toilette?
Wondering if, on a 15 ft pocket solo cruiser for inland waters, the head
can be located in the cabin and the holding tank ouside the cabin. The idea is to run a hose through the aft cabin bulhead and put the tank under the bench seat in the cockpit where the odour would be outside. If the tank were directly under the seat in the cabin the discharge would be stright down. But to run it at an angle through the bulkhead might not leave enough of a gradient for the discharge to work. Is this a realistic design problem? Is it worthwhile to try to put the tank outside? -- ------------------------------------------------------------------------------ William R Watt National Capital FreeNet Ottawa's free community network homepage: www.ncf.ca/~ag384/top.htm warning: non-freenet email must have "notspam" in subject or it's returned |

Bill, the ONLY thing that would make ANY sense on a boat that size is a portapotty--toilet & tank completely self-contained. If you don't want to mess with carrying it off the boat, there are models that can be permanently installed and fitted for pumpout...the only plumbing required is a vent and pumpout hose to a deck fitting. Otoh, installing a marine toilet and holding tank would require a thru-hull for flush water intake, a hose and vented loop...another hose to the tank, plus a tank vent hose and thru-hull. To gain any capacity over a 5 gallons portapotty, you'd need at least a 15 gallon tank. Storage space is in short enough supply on 15' boat...you don't need to use up a major portion of it with a holding tank. Properly installed and maintained, there should be no odor from a porapotty OR a marine toilet and tank.

I hit send before noting that you're in Canada. Canadian law requires
that all portapotties be permanently installed and fitted for pumpout. Since most mfrs offer models that are designed to be--look for an MSD designation in the model name/#--this won't present any problems. The best quality IMO is the SeaLand Sanipottie...their 964MSD holds 3.2 gallons, their 965MSD model holds 5.6 gallons. Price for the 965 is about $125 USD at West Marine...you can prob'ly beat that price by quite a bit if you shop hard.

Peggie - on a related subject, I have a friend who is converting a small
powerboat for pump-out duties in the harbour here (RI). Any regs she should look out for that apply specifically to pump-out boats as opposed to sewage in general? Steve "TIA" |

Any regs she should look out for that apply specifically to pump-out boats as opposed to sewage in general? Yep...but it's the state and the CG that'll have to tell him what they are. If he's already begun to convert the boat without first getting all his legal and regulatory ducks in a row, I wouldn't hold out too much hope for it to be a successful business...how can he equip the boat to meet regs if he doesn't know whether his boat meets 'em or even what they are? Most states require permits, a business license, liability insurance, HAZMAT insurance (in case of a spill), some reqire at least a 6-pack license (pumpout boat is a type of "vessel for hire"), his boat will become a commercial vessel and therefore subject to the CG regs for inspected (commercial) vessels...and they may make him submit some kind of "study" on the impact of the volume of toxic holding tank chemicals his boat will hold going into the sewage treatment system (I do hope he doesn't plan to just out beyond 3 miles and dump...that would have a far worse impact on the environment than if every boat he's pumped out went to the same location, anchored and flushed directly overboard all day). Running a pumpout boat can be very time consuming--and expensive...'cuz unless he also rinses out the tank each time too, he won't be providing a complete service...how much down time he'll need to empty HIS tank depends on the size of it...other down time depends on whether he spends the money for a pump powerful enough to have enough head to pull waste out of tanks quickly--to pull it out of some boats at all--and how dedicated he is to preventive maintenance. I hope he's researched the profitability of going into the mobile pumpout business...'cuz all of the above--or even part of it--easily explains why most of 'em have to charge at least $25/scheduled visit to boats with the smallest tanks and $50 or even more for an emergency unscheduled call.

It is a safe assumption that only a very small percentage of all "commercial" boats are "inspected vessels." I seriously doubt if any of the small pumpout boats working in the US are inspected vessels. Rick |

snip-de-dip! Peggy, Thanks! That is exectly the kind of info I needed to pass along. She has already started "converting" the boat, and has not been and done most of what she should have been and done. This should at least give her something to do during the winter ;-) Thanks again, Steve |

"Inspected vessel" is terminology, not necessarily practice. Technically, any vessel engaged in commerce, including charter or rental, is an "inspected vessel." How strictly the CG enforces the regs pertaining 'em on smaller ones is another matter. It varies from port to port.

An "inspected vessel" is a legal description of the operation, manning, construction, and maintenance of a vessel holding a Certificate of Inspection. The USCG very specifically differentiates between an "inspected vessel" and an "uninspected vessel." They are two distinct and separate regulatory areas. Rick |

You may have caught me flat-footed on this one... I was only going on what I was told by someone who ought to know. I guess I'd better do some homework, 'cuz I don't like giving people bad information.
