IP35 Holding Tank

grfoggynotion · #1 (**permalink**) 09-29-2006

I am considering the purchase of an IP35 for extended live aboard cruising but am concerned about the small (15 gal.) holding tank. So far no one seems to think a larger tank can be installed. The only help the factory offered was to check on this website.

Can anyone offer anything regarding installing a larger tank on an IP35?

Thanks

Dunno about plumbing spaces in the IP35, but things to also consider:

If you are CRUISING, surely you can jog outside the 3-mile limit and pump the tank out?
Or, stop by pumping stations from time to time?

Options to make your tank larger than it is include adding a urinal (simple and cheap!) or switching to a Lavac head, so you don't need to pump as much water into the system every time you use it.

The usual places to hide a larger holding tank are in the bow, or under a settee.

Thanks for the response, certainly things to consider

Go to the Island packet list and ask the question. There are a whole bunch of IP owners who might be able to help you. Click on the Resources tab at the top of this web side, go down to Email lists then to Island packet, sign on and ask your question.

Of course, holding tanks are only needed when inside the 3 nm limit. If you install a Lavac head, to extend the amount of time the tank will work for, by minimizing the water needed to flush, and you modify the installation with a diverter valve and and a Y-fitting, you can use the diaphragm pump that pumps out the Lavac to empty the holding tank overboard.

Pumpout facilities are pretty rare outside of the US from what I understand.

In my ignorance I didn't even think about that! The implication being that outside the US you had better be prepared to pump your own tank outside the 3-mile limit or put up with quite a stench when in port! Thanks Sailingdog!
