Hello,
Chris and I had a Sun-Mar on my boat before we got Baldock.
It was an Excel tweeked to my specification and marinised.
We are going to be doing alterations to Baldock soon which will entail removing a huge poo tank and we are seriously
looking at composting again.
When you have a composting toilet you have to manage it and this involves educating visitors in its correct use ie with the Sun-Mar not to rotate the drum every time you p.
All the time we used it we did not get any liquid run off and if we had have done it can be used as a liquid fertiliser (watered down as it is highly concentrated)
Carbon and zeaolite filter in the vent stack prevents any external smells and of course there is no smell inside the boat, unlike our dump thro pump out.
Seating position is comfy for those who tend to read the newspaper
