crappy subject: Thetford 135
Smart move to use a porta-potty instead of a marine toilet! Youíre saving on holes in your hull, no special holding tanks, a lot less hassle trying to maintain the patent thing and youíre meeting the CG regulations. Iíve used a 4 gallon porta-potty aboard my boat since I bought it more then 10 years ago, and I lived aboard! I needed to dump it about every 10 days to 2 weeks when I was alone.
It was no big deal, taking it ashore to the head at the marina and pouring it down the toilet. Put some rinse water in it in the shower, and dump that too and itís all set to go back aboard. Thetford makes some nice deodorant that is environmentally friendly.
I did have an incident one time when the thing was about half full. I sailed into a severe knockdown, possibly 60 or 70 degrees over and the thing rolled off its perch and landed upside down. The force of the fall must have caused the valve to open slightly. Its contents of nastyness oozed down the bilges through the limber holes. I didnít get below to discover this until I had made in some time later!
Sure, it was a mess that needed to be cleaned, but I still have my boat! There are others who have had marine toilets that donít, or have had other issues like siphoning or faulty joker valves and bigger messes then Iíve had!
Now the head has been moved from up forward to a place just above the deepest part of the bilge, underneath the bridge deck. It serves as a seat for my nav station too and it is locked in place with braces and bungeeíd when not in use!
