Thanks for the laughs gents.
It’s three weeks ago today since we departed Mooloolaba/Noosa to head north quickly some 500 nautical miles to the Whitsundays, arriving a week ago. Our assessment was that the South East Queensland region, with Noosa its northern most community, was teetering on the edge of an extended COVID lockdown, whereas northern Queensland regions where far less likely to be extensively locked down.
So we cut and run with the bare bones of Great Sandy’s new gravity-draining black water holding tank, head enclosure, and basin in place, but with temporary electrical wiring, and no anti- siphon venting on the head. So over the past three weeks, we’ve had to scrupulously close both of the head’s seacocks immediately after use.
Great Sandy’s previous black water holding tank was below the water line, required Y cocks on its input and output, and regularly malfunctioned. Her new black water holding tank is located above waterline, and once into open waters can self-drain into the drink by opening a single seacock. The system is simplicity itself. A budget TMC electrical macerating marine head draws water into its bowl, and when flushed macerates the waste and pumps it into the top of the black water holding tank. The bottom on the tank is plumbed to the through-hull seacock below. When the seacock is open, gravity does the discharge work. If the seacock is closed, black water waste accumulates in the holding tank either for gravity discharge later in open waters, or for pump out at an approved facility.
The first pic shows the new basin cupboard, and the new black water holding tank is location behind the new head enclosure, with it’s the lid down, is to the right. Lid’s up in the second pic. The head used to sit in the open, and it's input and output hoses looked like confused spaghetti. The child bride wanted a cleaner look, hence the new head enclosure. The top of the head enclosure’s lid is at approximately water level. The bottom of the black water holding tank located behind the basin is just a few inches higher.
Yesterday, I completed permanent electrical connections, and installed a vented anti-siphon loop to the head’s bowl input loop. The holding tank is vented to the anchor locker, and acts as the anti-syphon vent on the head’s output loop. The final look will be all white, with a few varnished timber trims. This will not be tackled until we return to Noosa.

Re: ST21 'Skinnydip' build, and boating adventures, Noosa, Australia
Some good ideas there GB. So what do you know about composting heads or think of them? I ask because I am not sure I will be far enough offshore very often to pump it over the side.
Re: ST21 'Skinnydip' build, and boating adventures, Noosa, Australia
GB everything is looking good there. Question why vent the holding tank to the anchor locker, why not vent it over board with a clam shell vent covering it. I would not want my anchor locker smelling like shit. Maybe I missed something here. What size hose is this.

Sorry Fuzz, I have no experience with or knowledge about composting marine heads, nor do I know anybody who does.
The previous below waterline holding tank vented to the anchor locker without stinking it up, so I'll see how the new one goes. If it's a problem, your clamshell approach can be pressed into service. Thanks. The old vent line was 1/2" ID, the new one is 3/4" ID.TomW1 wrote: ↑Sun Oct 03, 2021 3:19 am GB everything is looking good there.

I spent yesterday doing maintenance work on Great Sandy's decks - patching up dings to keep the decks waterproof. The decks are finished in sprayed in 2 pack marine paint, so I'm brush applying the same brand's 2 pack primer then topcoat for the touch ups. I awoke last night with the runs. Lesson learnt. Treat toxic paint fumes with the utmost respect. I'm pretty subdued today.

Sounds like you got the head squared away just in time. Hope you feel better.

Thanks cape man. I awoke this morning feeling fit as a fiddle.
Then a sparkling 15 nautical mile beam reach under sail from Nara Inlet to Shute Harbour busted open the day.

This article has a review of composting toilets. I have no experience with them. sailingwiththewynns.com is a vlog of a couple sailing their catamaran. They use a composting toilet and have a video of it somewhere in their history.
