Mooring fees don't pay for that though. There is no part of the fee set aside for this. The fees essentially go into council's consolidated fund and then the HM is funded from that. No special jar labelled "getting rid of old shitters fund" that only gets income from mooring fees.
That's an accurate summary IMO. Stretching the topic but abandoned cars are also dealt with by local councils, some are shitters that tourists couldn't sell before departing the country, Q town is particularly bad apparently, still at least cars have a half decent scrap value and are cheaply recovered/transported.

His stat of 40% of approx 3500 vessels effectively abandoned at the mooring, and a disposal cost of $20000 each time with large steel vessels much more, a $50 annual fee increase is not going to go far.
Its confusing because in the interview "Matt from the Harbour Masters office" agrees with the interviewer that Rate Payers are unaware they are picking up the tab, implying that rates are funding the salvage.
-
This is third hand so Perhaps someone here has more correct detail but apparently one or possibly two steel boats parted their moorings in the recent blow. They were moored on the Tamaki in the vicinity of the PYBC and significant Damage to other vessels ensued with one possibly sunk, I suppose we will pay via increased insurance premiums. Harbour Masters dealing with abandoned boats is a worldwide problem affecting oceans, rivers and lakes.

Again, anyone who has the desire to go offshore cruising, go now as the window is closing rapidly.
How so ?

So the cabinets are coming along. Next I have to figure out how to do the lids and seals.
The old ones were hinged, but only sealed on 3 sides, not along hinged edge.
Anyone got any clever ideas about how to make a lid that seals properly and hinges? Maybe I'm over tired, I can't think of a good way right now!
And thanks to Tony (ynot on here) for the insulation!
Nice work Matt, what is the white liner material ? looks like 6mm thk GRP or something similar ?

Enertec Marine has had solid state lithium-ion for a few months now.
They no longer market or sell the liquid electrolyte lfp batteries in favor of the new technology.
I can't find a source for the cells to DiY But I believe they are only available in pouches.
https://enertecmarine.co.nz/product-category/batteries/lithium-ion-solid-state/lithium-ion-marine/
I was skeptical because a few months back Yoshino's advertised SS battery was exposed during independant teardown as still having some liquid electrolyte albeit it was only 3% I think. The companies' marketing department eventually admitted they got a bit carried away. This one however looks legit and there are one or two others out there so maybe we are finally at the beginning of the solid State era , good stuff !

Senator Collins, thanks for your time .............Can you book me a cab

1) for the mechanics. I have replacement 4hp 4 stroke yamaha. The old one always started on the second pull. This one on the 7th. Do I have to live with this.
Change the plug as well as cleaning the carb, or at least clean it and check the gap.

Otherwise they would have to tow it outside of the environment, there is nothing there luckily.

Some looks like one of the old Altex (tauranga) epoxy undercoats, dont think it is Coppercoat. Prob to cover earlier osmosis jobs.
Agree.

It would be interesting to know the details,whether it was actually the lithiums that started it, brand of lithium, BMS , configuration for charging, safeguards (or not) in those incidents.
AGMs of similar capacity cost more than my Lithium. That said, you have got to have X amount of geek in you to be comfortable
with the change-over, and could be dependent on what capacity you can currently charge at and whether you have already tweaked it
with configurable external regulated alternator . I already had the perfect setup for DIY LiFePO4 and BMS of my choice.
Horses for courses. If you want completely hands off autonomous system for the electrically impaired, it is going to cost.
We have slowly upgraded the DC power/charging system since we purchased the boat in 2017, lithium wasn't on our minds in that time it was just an attempt to better manage the AGM batteries .
Now we are considering the switchover and I think the only extra component we need is a DC to DC charger and even that we could probably dodge as the start battery has its own alternator. The Balmar house alternator is grunty enough for the purpose, some settings to be tweaked changed obviously.
ie none of the components are unique to Lithium batteries.

LiFePO4 are Lithium-ion batteries.
What makes a Lithium-Ion battery a Lithium-Ion battery, is that lithium ions move from the cathode to the anode during discharge, and vice versa during charging.
Saying that LiFePO4 is OK, but Lithium-ion is not OK, makes no sense.
Yes, LiFePO4 is a safer chemistry, but it isn't the safest Li-ion chemistry, not by a long shot.
99.99% of LiFePO4 batteries on the market have a liquid electrolyte, this electrolyte is highly flammable and explosive. If you want to stick with LFP and would like to be an order of magnitude safer, than everyone else, then you need to be looking at Solid State Li-ion batteries.

That's the first solid state battery I have seen that you can actually purchase as opposed to the ones on Youtube that are always "right around the corner" do you know when it became available ?

Id just like to re-iterate -the issue is that (IMO) Lithium Ion has no place on a yacht. LiFePo4 only!...
I agree IT, I used Lithium ION in electric RC models and albeit rare I witnessed one or two self-incinerate at the field (not mine). We have a 320 Ah LiFePo4 in the campervan It has the Victron internal and external BMS plus fuses, isolation switches, Anderson plug, metal container, external venting yadda yadda , its probably safer then the FLA in the Carpenter .

Following that, how many people have a second exit point from the saloon? and could everyone onboard actually get out of it (assuming a forward hatch with no steps)
I think I might have posted this before but when building the Carpenter 29 I was keen on a soft headliner until reading about a fire in a production yacht in the UK as the owner told it.
There was a fire in the saloon, cause unknown but the skipper was on deck and I think his wife.
Two children were in a quarter berth (screaming)
Skipper tried to rescue them via the main companion way but was defeated by heat/smoke.
Skipper then went forward to access the saloon via the foredeck hatch but upon entering he found the vinyl headliner was melting generating thick toxic smoke and raining balls of molten plastic.
Skipper eventually smashed his way through the Qtr berth lid from the cockpit with an axe and dragged the kids out. (don't recall where the axe came from)
Both kids survived but spent a week or so in hospital due to smoke inhalation.
So I stuck with a painted ply headliner and moved the foredeck hatch forward so it was above the Vee Berth, there wasn't a chance in hell of a child exiting the fwd hatch in the factory location, even an adult would have struggled.

Very good observations from IT and K4309, at the tail end of our 2023 ICR cruise we kept getting brownouts on the Raymarine displays. Long story short we were checking connections when I nearly burnt my hand on a bus bar . It transpired we had a high resistance connection on DC feed so hot in fact that that it was melting cable insulation in an area that was absolutely jam packed with wires. Hard to predict a timeline to smoke production but that was probably the closest I have come to an electrical fire in 40 years of cruising, certainly nothing to do with the battery other than it supplying the smoke. Not wanting to ruffle any feathers but Dr google reports LiFePO4 batteries are generally considered safer than lead-acid batteries.

So, you know when we had antifoul that really worked with the "good nasties" in it - was it really that damaging to the ocean when we consider how much damaging environmental waste water is released into the ocean by all the worlds cities, and industrial centres? The "damage" that proper antifouling did to the environment surely has to be infinitesimal small in comparison? Or am I just doing sort of Joe Rogan type "Bro Science" here - though I feel the comparison I make is probably valid.
I hear ya, and TBT was before my time but I must admit wikipedia paints it as pretty evil Sh*t once it leaches into the envirramint, it does a real number on the innocent critters. On the other hand if I recall correctly they allowed its continued use on large ships for many years https://en.wikipedia.org/wiki/Tributyltin

Paint is Less than questionable. It just doesn’t bloody work any more. Spoke to Jim Lott yesterday and he’s saying a pint of Ivomec sheep drench with the paint. No he hasn’t tried it. Yes, there’s lots of these sorts of urban myths doing the rounds. Apparently there are a couple of products approved in Europe which are working. But not here yet. I’m pretty sure the European standards would be good enough for us so not sure what the holdup is.
I have heard of Roundup being added as well, no idea if it works,

After 30 years in contact with Aluminium I suspect additional shop time might be needed drill out some of the locking grub screws and careful use of heat to extract the bronze ring .
They will need to clean the crack surface to thoroughly remove any oxidised material, it can be a surprising amount, they will also remove the anodising around the weld margin. Post repair you will need to get the drum stripped and re-anodised. It looks to be a relatively thin wall casting so distortion might be a risk and as already mentioned the welded area will be weaker than the parent material. It might be worth asking lewmar for the heat treatment spec as the repair shop might need that info.
I would see if there are any engine build shops that do weld repairs on Aluminium cylinder heads.

Taking into account you said victron and battery, I am assuming you understand that a victron battery is just a box with batteries (cells) inside it..
Why do you want another box? And where will the box be?
Understanding why you want a box to put your batteries in to will help with material selection.
The outer casing on the Victron Battery in our land yacht is Aluminium ex factory , the electrical inspector considered that to meet the rules without further ado but I built an outer box in ply and lined it with several layers of dry fibreglass from a heat blanket (ex bunnings) . A lithium battery apparently can burn at close to 1000 deg C so aluminium will eventually fail although by that stage you might be in the raft anyway. I think a steel/SS light gauge folded angle frame with some sort of refractory lining or fire proof lining, plenty of options/products out there in blanket or sheet form. .
Question is what would you do if the battery caught fire (any battery not just lithium) ?

No one local would fill mine as they need to be NZ registered and certified - seems odd if they are available as close as Aussie and no manufacturer has bother to register them here as corrision on steel ones in a marine environment is an issue
The bottle on our boat is aluminium with a brass neck fitting sold to me as a refurbished unit by Tank Test Laboratories in Puhinui Rd, I have painted it and keep the neck treated with Lanocote but as already commented you would think it would be of equal concern since I have seen dissimilar metal corrosion cause cracks in thick aluminium, particularly cast material.
