I would be very very keen to hear if you can name a gas fitter that will sign off (issue a gas certificate) for work on part of a system if the remainder of the system doesn't comply with the standard. I'm not wanting to sound argumentative, but after my recent personal experience of trying to find a gas fitter that understands the basics of NZS 5601 part 2, I think finding someone that would do what you outline would be akin to finding rocking horse sh*t. I asked gas fitters if they would do this, as what you say was my interpretation of the standards as well. I had intensive discussions

That is quiet irrelevant, especially for insurance purposes. Two reasons: The insurance co's via the condition assessment reports want to know if the boat complies with the current NZ standards, not the standards from 1975, and If a gas fitter touches anything on the system, then the whole system needs to be upgraded. Noting that you aren't allowed to touch anything yourself and have to get a gas fitter even to crimp a hose clip. There are several reasons a gas fitter may need to touch the system, one being the standard flexible hose (1869 class C) that costs $12/m from Bur

What brand?

All the above is why I went for lead-carbon over lithium. Much the same reason as why Aardvark when for a kerosene stove over LPG. It avoids a whole lot of compliance issues. Standard charging profile and voltage profile, no need for a BMS and no risk of blowing the alternator in an uncontrolled load dump.

Unfortunately my official copy of NZS 5601 part 2 is via a work subscription to the AS/NZS standards and it is extremely heavily embargoed with copyright protection. I couldn't even copy and past single clauses, or print it. However, I checked the key relevant clauses with this draft copy for consultation and the key clauses are unchanged (the ones I mentioned in my post above). I can't vouch that there are no differences in the whole document but this is a good starter for someone wanting to understand requirements. Especially for many of the tedious things like set backs for flammable s

Crickey aardvark, are you suggesting sailors might engage the services of hookers?!? That is a bit controversial, what would the good folk at the Royal NZ Squadron say? (Any port in a storm) PS I wonder what economic impact hooker have?

Ah, but the number of international attractions / events available to Chch is significantly limited. The percentage increase of economic benefit due to SailGP is substantial. If the All Blacks and Six60 contributed $1.4mil combined, and SailGP contributed $1mil (net, as you say) then sailGP has increased economic contribution to Chch from International Events by 71.4% That is an extra million bucks the good hotel operators of Chch would not have got if it weren't for SailGP

Oh neat, Lies, Damn Lies and Stats. so what you are saying is that SailGP had 30% greater economic benefit than the All Blacks and Six60...

I have recently investigated this myself. Two out of three gas fitters (recommended by various people for marine work) do not know or understand the gas standards NZS 5601 part 2. For an installation like yours with a single appliance, you are allowed to use flexible hose to NZS 1869 Class C, which for the layman is standard BBQ hose, costs $12/m at Burnsco and costs the gas fitters $4/m. Two of the gas fitters claimed for that single appliance install I needed copper hose with flexible stainless steel at each end. The additional cost was several thousand dollars. Additionally t

Others may conclude that because there is 15,000 of them, one yacht race isn't going to cause their instantaneous extinction. ;-)

But there isn't any science in this issue. Coutts has been told he can't hold SailGP in Feb cause of dolphins. We aren't talking nuclear fusion of metaphysics here. At best we are talking local bylaws, in that he wants to hold a yacht race in a commercial port, that also has a legislative overlay as a marine sanctuary. We are told the dolphins are endangered. 'Endangered' isn't a scientific fact, it is a human construct based on opinion. Sure the death rate might be higher than the birth rate, then again it might not be (I haven't seen the peer reviewed scientific report), but

Not saying this boat is, but many of the Iwi that were awarded quota then contract foreign boats and crew to fish it for them. There were HUGE problems with slave like conditions, brutality etc toward crews and what not. There was a series of news storeys some time ago (pre covid) about this. I believe those boats were from Korea or Taiwan. They were certainly bottom rung in terms of maintenance, age, crew welfare and what not. Iwi were washing their hands of the issues claiming it was intermederiares that were doing the chartering. Strangely various vested interests were keen to keep such car

What does the green and red represent on the track? would that be speed? If so it would appear they've been breaking down / going dark ship, getting it going again and breaking down again. Hopefully they have just drifted onto the Noises, which will be a whole lot easier to recover from than hitting it at speed.

If I were a religious zealot I'd be proudly supporting the current genocide going on like all the other religious zealots, and sending more bombs, but I digress. This little segway about science explaining gravity started because of the refrain to only use peer reviewed scientific papers to win the discussion about dolphins and boats, instead of just applying some logic. People often reach for the old 'peer reviewed scientific papers' in the hope that it is some sort of infallible fact. Science is by far incomplete in terms of our understanding of many things. There are examples of scienc

That fairly much proves my point BP. Scientists can describe gravity, and quantify it, but they can't explain it. So, what causes gravity?

You are getting a bit selective there CD. Sail GP can't get the dates they want in Feb cause of the dolphins. They have been told they can only have dates later in the autumn. Hence no Sail GP. And what about the actual risk? still need peer reviewed scientific research before you'd want to hazard a comment on that?

Crickey, you lot are easily triggered. What is the risk? What has to happen for one dolphin to get hit? Foils make a fecken racket. They are very, very noisy. More so underwater. The F50's also happen to move at about the same speed as the dolphins primary predator. Dolphins tend to be fairly well adapted at getting out of the way of their primary predators. Most of them have done it before. So we have two factors that work to reduce the risk of hitting a dolphin. Then we have the fact they have a significant population. So hitting one is going to have a 0.00667% reduction

I'm going to need more convincing that a population level of 15,000 is nearing a tipping point. Sounds like there is a sh*t tonne of them. It is clear the risk is not balanced with the economic benefit.

So what is really happening is the Hectors dolphin is listed as endangered because it's population is decreasing, not because of the total population size. When all this kicked off, I was under the impression there were only a few hundred of these dolphins, that they were very rare and thus required protection. I couldn't really reconcile that with the fact that I have seen them myself without even trying to look for them. I expect many people are confusing the Hector's endangered-ness with the Maui's 'on the brink of extinction-ness' and conflating the issues. Then I found out there are

This endangered thing. There are 15,000 of these Hectors dolphins. That sounds like a sh*t load to me. At what point does fifteen thousand become endangered? Are people getting mixed up with the Maui Dolphin? the Hector's west coast cousin. They have something like 56 left - that is clearly critically endangered, and clearly warrants protective measures that come with economic cost to other people. But 15,000? how can you justify significant economic disruption when there are 15,000 of them? It is not proportionate.

Is the boyfriends name R2D2 by chance? Or C3PO? (Mechanical men)

The Maxtek, 2 burner with grill and oven. It was the cheapest option going. Did look at the Eno. Our current one is a Flavell, very solid with white enamel. In my view any or all of the new ones feel light and cheap in comparison, and all come in stainless only. Wasn't intending to get a new stove and was still pondering what to do about the whole gas certificate thing, then Burnsco had a 20% off everything sale back in Feb. We've never seen stoves on sale so bit the bullet. I know of at least two other boats in the river (maybe 3) that went and got new stoves at the same sale. The Flavel

You can get cans of suitable enamel spray paint from many suppliers, including from Bumblings, budget about $30. A piece that small you could clean up without sand blasting. Wire brush, or a small bit on a dremel. If you don't have a dremel you could buy 5 or 6 for the cost of getting someone else to do it. Service kit you are supplying already. Just need to work out how to push the bearings - not complicated. We spray painted our old engine, and many of its components, it lasts fine. We went with a nice gold colour, to reflect the total cost of maintaining a boat

If no one comes out of the woodwork hear, Advance Trident (the main retailer) might be worth speaking to. The other direction to go in is a Dickinson diesel stove. They seem popular on the workboat type boats (fishing etc), like the more traditional displacement boats (Carey boats for example). Probably (almost definitely) don't gimbal, but might be a source of 'been there done that' information. A Wallas stove is probably better suited to a yacht (size, space and gimballing), but if you are to do a deep dive looking at diesel stoves it's probably worth understanding the other option on t

I would love a Wallas stove but unfortunately haven't won lotto yet (maybe cause I don't buy tickets). They look like the ducks nuts, just not very cheap. Must be a huge benefit only carrying diesel instead of all the faffing with LPG when on extended and international cruising. Just pruchased a new gas stove in order to get my gas certificate in order to placate the insurance company. Was looking longingly at the diesel stove options. Had a good look at Wallas diesel heaters as well, ended up going for a far lower spec'ed one.
