So currently there is no retrospectivity clause. Every boat would have to meet this standard. Part of the draft says that there may be NO PVC insulation on cables. This means every boat I know of would need to be re-wired. There is a requirement for fireproof (and certified) battery boxes for all Lithium chemistries. This means a system designed by an engineer, and approved by a fire engineer. IMO this is totally impractical. There is a requirement for negative pressure in the battery compartment, and min airflows, yet it has to be sealed fireproof. I have posted my comme

Lemon juice does the trick, or citric acid from the supermarket. Leave it overnight

Well looks like the NZ spring is colder than November at 60 north. We are just getting snow down to sea level now. Has been a few hundred metres up for a while but now down to deck level. Doesn't make getting out of bed easy each morning.

A cloth buffing wheel on a bench grinder would make quick work of it, but brasso and a couple of beers to while away a relaxing arvo on the veranda also works well and is more satisfying.

Lemon juice and baking soda into a toothpaste like consistency. Wax on, wax off. Or Brasso if you want to go down the chemical path. Then finish it with a metal lacquer like protectaclear.

It will be the AU and NZ standard when ratified. However it has to also be cited in legislation to become a legal requirement. Currently NZ legislation cites no standards for recreational vessels UNLESS that vessel has a CONNECTABLE POWER SUPPLY. (Fundamentally for most boaties that means an EWOF). The current cited version for an EWOF is the 2008 version of the standards. However any inspector can choose to align with any standard they want... They operate independently and only have to comply with the 2008 standard which means they can choose to comply with the 2025 st

If it’s sealed, then negative pressure will only last a few seconds after the thermal runaway starts, and a little after that it won’t be sealed anymore, after the bomb you have created goes off!

Dairy Flat Caltex does gas fills it but only before 5pm when they have 2 people there. Always pays to ring them to double check before turning up.

Indeed. There is one here at GH that's using the 2025 draft already. I think that's wrong, as it is not even a ratified standard yet, and may not be...
