I fear it is too late and too difficult. Would the HCl dissolve the concretion or just loosen it? Then I'd have to find a way of getting it out.
I've come up with a plan to lay a new pipe but now have to think about whether to leave the old in situ or get it out somehow. That waste pipe is hard to work with in the confined space.
If I leave it there the pong will stay for long. If I get it out In pieces it'll spill its load all through the bilge (under said floor).
No good options really. A case of prevention being waaaayyyyyyy better than cure.

I don't recall the chemistry of your stuff in the waste pipe, but if you are desperate for a solution you could try a heat exchanger cleaner. They get the same sea-salt encrustations of heat exchangers in seconds to minutes.
Barnacle Buster works very well. It is moon-beams expensive though. An alternative that is highly recommended by professionals (but I haven't tried) is Rydelime.
I'm fairly sure the basic chemistry of the stuff in your waste pipes is the same as the stuff in heat exchangers. With the HE it forms quicker due to heat and evaporation. It is all marine salts (Chlorides, sulphides). The urine makes a different sort of salt which I can't remember the name of, but I would think something like barnacle buster (phosphoric acid) would have a better than even chance of nuking it.
Great idea. Was thinking caustic soda (draino) but acid v alkaline is the question.

Yes I always do that especially white vinegar but boat is new(ish) to me so I guess not everyone does that.

Another poo pipe question unrelated to Parnell.
I have a head where the outlet pipe is built in under the floor. It's a fixed floor as is also the shower.
The pipe is nearly level and over decades (2005 construction) poo et al has been sitting and doing something to the pipe. It is now seriously blocked through some sort of scale/plaque/calcification (I know it is not calcium but you get the idea). The plaque is like a plaster lining and is now blocked solid. Can't get a wire etc through.
We've tried unblocking with all sorts of machinery but think we have compacted it.
Last roll of the dice before saws are called to action is whether some chemical can be used to break it down.
Any ideas? Experience?

Yeah or bail from Auckland . Plenty of yachting in the regions just not as many boats or black sails .
Plenty of black sails on Tauranga

Unlikely unless the rules are rewritten, RRS requires humans to trim the sails etc. On the AC boats its pretty much oil pumpers and button pressers with a tactician pointing the way.
The RRS are for most sailing rsces but not all. Any race committee can change them.
-
Certainly not racing as we know it.
4 crew on a 40ft foiler.
No one actually looking at the sails.
Auto pilot making ride height decisions.
Adjustments all done by buttons.
But. Did you notice the amount (frequency and range) of main traveller adjustment? A human would probably never do that much.
But there were clearly crews that knew how to get the best from the gizmo's provided and those that didn't.
But the results from le French with least time in tbe boat show that the tech can be mastered quickly.
Im sure that this is all progress and We will see this sort of stuff available at a high end soon (ie super yacht and maxi) and then trickle down to weekend racers.

Can we please book in 20kts Southwester for Friday 20th October?
Precisely what we need. Legends regatta - Tauranga to Great Mercury Island.
And then NW on return on Monday.

I think we did. I recall a conversation and I think BP's daughter played with him before he died. And we discussed his boat being for sale.

Yacht is Dutch for fast ship (another Dutch word) and i understand that Americans began using 'sail boat' to distinguish from steamers. So yacht started to be reserved luxury or racing classes. English were more traditional and stuck the older usages. Something like that.

There are indeed 7 ropes: per https://classic-sailing.com/article/how-many-ropes-boat/.
Bell rope
Bolt rope
Tow rope
Foot rope
Man rope
Top rope
Heel rope.
A Cunningham is not a downhaul. A downhaul is used to pull down a yard. The Cunningham (designed by a kiwi) is used to tighten the bottom luff of a sail.
The other duplication terms developed due to local usage.
Boom vang appears to be a Dutch term (where we get lots of sailing terms) and Kicking strap an English one- both meaning to stop the boom from kicking up.

I got lambasted on SA by a Texan boatbuilder for using the term pushpit . Apparently they called it the aft pulpit/aft safety rail or some other things. He really hurt my feelings
Not surprised. I gave up on SA long time ago. It is the wild west of the Web in my view. No wonder a Texan feels at home there.
Nautical terms are intended to be clear and definitive to avoid confusion. Hence, there are no ropes on a boat. But when you broach and are laying on your topsides you are also laying on your beam ends.

It may not be helpful to an Auckland based boat but looks like t there is lots of capacity at Whangamata as an interim.

That is just brilliant. Highlight of my day.
You really do need to write that book. Maybe your daughter can ghost write it for you she is clearly talented and charismatic enough.
Ps. I've never really liked Jimmy Buffet but David Crosby had a similar lifestyle.

I think they'll be cautious. They started the trip with 2 reefs and no4 which I'd never used.

I just read the delivery trip of Pork Chop (Elliot 10.5) which has gone from Tauranga to Wellingtton.
There's a photo of tooth marks and teeth on the bow as evidence of an Orca bite.

One can only conclude that 99 out of 100 readers are gun shy of any question about apparent butt size....🤔

That sounds interesting. Should introduce him to Crew and he could keep us informed.

Did the classic guys show interest in them?

Looks cold.

BTW I am not defending them merely aiming for balanced reporting.
I have a lot i could complain about the MNZ system.

The conclusion of the tale is that the saw will come out tomorrow. The pipe is I'm too difficult access to fiddle with chemistry.
I have two heads and will do the HCl treatment on the other. Basically, flush it through from the bowl to the holding tank. Then let it sit for a day or two and dilute it with lots of water and empty it to the sea.
Will probably replace the jabsco pump after.
