Island Time

Well, if nothing, next is to pass it on to an MP - isnt this Govt supposed to be removing red tape

Ok, further to that. Today I have made a complaint to the Plumbers, Gasfitters and Drainlayers Board as follows. "I would like to complain about the current situation regarding LPG on Boats. To get a gas cert for the vessel is currently impossible without a complete reinstall. The issue is that despite current standard, page iii "This Standard includes a statement that its requirements do not apply retrospectively" the gas fitters are insisting on compliance with the CURRENT standards, even for an EXISTING installation. This is in direct contradiction to the current standard,

I totally understand your position. It's a shambles and I don't believe was the intention of the standard. The issue is that the gas installers wont take the "risk" of signing off the install, even though it IS compliant with current standards (Through the retrospective clause). They feel they are at risk, and are not prepared to accept that "risk". IMO this is a failure of the gas registration and education system. My boat is in the same situation as yours - built in 1988. My insurance condition report stated "gas compliant at time of install" and that was accepted. There are

Sorry but that is not correct. If a boat complied with the regs when it was built it still complies, unless in poor or unsafe condition. That is what "Retrospective" means. I agree that if anything is changed, that needs to comply with the regs at the time it was changed. You do NOT need to redo the whole system just to replace a gas line (for example). The issue is finding someone who actually understands the regs. The insurance co "condition reports" I've seen just say does the gas install comply with NZ standards, not "Current standards" the "current standard" says cle

The main thing to note is, from page iii "This Standard includes a statement that its requirements do not apply retrospectively"

I have taken multiple sets (3) of lead carbon batts out of customers boats this year - premature failures, all approx 2 years old.. All have gone Lifepo4

Because the battery will turn off, possibly at a critical moment - no lights, no nav gear etc. Known as "dark ship". That's what the regs are trying to avoid.

Great info!

The standards makes no allowance for "leisure craft". ABYC E13 OR AUS/NZS 3004. Just because a craft is not inspected doesn't exempt it . Yes I realize a standard itself is not law. Yes, there are situations that could take out all the BMS units together. High (or low voltage) is an example. Much more likely is a single cell tripping one BMS - high or low temp, high or low voltage due to balance or other issues. IMO.

Just a note here. That install does not meet ABYC or AS/NZS standards for a Lithium install. That COULD cause an insurance problem. Most of the issue it it has no external comms to "provide visual and audible" warning of an impending shutdown - but it's unlikely to ever shut down as there are, in effect, 4 BMS's making 4 banks...

Bow batteries are cranking batts, (or should be!) So voltage is what matters. Ideally the balmar should be controlled by the battery BMS, so it does have current measurement etc. If it's not, it should be. The bms can switch the balmar ignition wire safely. So, when the house is a bit down, turn off the start and thruster batts, and make sure the alt is putting out full output. If not, adjust the balmar till it is. Combiners for charge are not great - the banks being charged are different types and chemistry, and have different charge profiles. Ideally alt to house only, and D

My point was that the rudder shaft appears undersized, and that the NZ regs re rudder shafts are what one of our leading designers suggests are "minimums".

Why is it under performing? Should be a pretty good setup. What continuous amps does the alt output, and at what alt temp? If it's not over 90 amps, then it's not set up right.

Most of the production boats don't have watertight bulkhead. Some have dams - didn't work great for the titanic! Also, an 85mm alloy rudder shaft wouldn't meet cat 1 here in NZ.
