It says in the description it was designed for coastal travel. A 36" prop might dig in a bit on the canals.

This has got to be a snip at £84k. I'm tempted..... Not. https://www.ebay.co.uk/itm/STEAM-POWERED-COAL-FIRED-NARROW-BOAT-65ft-cheshire/184114550444?ul_ref=https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F184114550444&rvr_id=0&rvr_ts=b03f4d9816f0ac3cc73399d2fff70e32&ul_noapp=true&pageci=50a529f9-527b-43ee-b7b0-2c7d4ee58d09&redirect=mobile

Having digested all of the above comments, so to speak, I have formulated some explanation for the behavior of my system. I think the blue the previous owner used killed everything and so no gasses were produced and there were no smells to start with . I stopped using blue after about six months and changed over to Silky but it seems the transition can take longer than I thought. If there is still blue in the system killing the bacteria, but not all of them, leading to some fermentation of the waste and some gas production which is venting along the pipe from the waste tank to the toilet. The non return valve is probably there to prevent the back flow of liquids but not gases. Hopefully with each new pump out the gas production will get less and less as a finally get rid of the last of the blue.

Ah yes well. Exactly. No the comment was to illustrate the anomaly between the smell before and after. Using blue no smell from toilet but waste tank very smelly. Using no blue toilet smelly but waste tank not so smelly. That's what I don't understand. ?

Yep the smell is now much improved if you see what I mean. However it's not the smell that bothers me but the fact it comes out the toilet. This didn't happen when I was using the last of the blue stuff yet when I did a pump out the contents were rank. That's Friday, I'll get back to you.

Ours is a Johnson-Pump which empties the pan when you use the macerator. You can then add about 1 inch of water if you want to.

Do you leave the water in it or is it part of the design like the s bend in a house toilet?

I inherited a half tank full of blue. I continued to use it with no smell problems for 6 months. We were in the process of changing to Silky when the pump failed. The smell we get now isn't too bad. It is not coming out of the vent pipe into the boat but out of the toilet itself. We had pigs on our farm, I never got used to shovelling their poo!

I have read several threads about smelly toilets but don't think they are like my problem. We have a bog standard set up with a macerator toilet feeding a large tank under the floor in the back cabin. All was working fine until one day in August the macerator stopped working. Took the pump off to find it was seized up. It had always seemed noisy so we think it may have been abused in its past as we had been very careful what we put down it. Anyway I bought a new pump and it all worked fine, only quieter. Then a few weeks latter we got a terrible smell in the toilet area. At first I feared a pipe had come loose but checked the ones I had taken off when replacing the pump and they were fine. Smell went away. But this happened again a couple of weeks later. It now seems to happen about once a week. We live on board so use the toilet several times a day. I have checked the vent pipe from the skin fitting by running water through it and that isn't blocked. It seems that the toilet is just as effective as a vent so should we be keeping water in it to stop this smell? Like the u-bend in a house toilet. We didn't do this before and never got a smell and we had the boat for a year before the pump failed. When I put the new pump on the pipe seal had a rubber flap on it. I cleaned off the limescale and put it back. Could it be this flap is the wrong way round and hanging open rather than closed. Should I have got a new valve? I don't want to take the toilet apart again if I don't have to. Any advice gratefully received.

I used to work for the Fields Studies Council about twenty years ago and they had a composting toilet at one of their centres. It was on a slight hill with the products coming out the back down a slope. This meant the fresh crap mixed with sawdust had a way to travel before it came out the back several weeks later. I had a 'nose' around the back and the bottom of the pile did look like compost. This was barrowed away for further treatment. This would be perfectly doable on a narrowboat with the front of the toilet in the well deck and the back around the stern gland...........

If only I had done metalwork at school instead of woodwork... That's just what I want without the cutter.

On it. Thanks for the recommendations.

Ah... Tall then!

How tall is it out of interest...............

Yep he is the chap at South Island Marina so I will give him a call thanks. Spoke to the chap from the Little Chimney Company but he no longer does exhaust stacks.
