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.

Interesting pic of the failed rudder shaft, which then sank the Arcona 460 after punching a hole in the hull. 85mm alloy shaft - on a 46 ft boat?

a frigate is generally regarded as the smallest vessel all weather all ocean capable. The Navy, like all of our very limited Armed Forces, are there to play our part internationally, and provide resources for Natural disasters. The ChCH earthquake and Cyclone Gabriel are classic examples - you want to discuss this with the people of Napier and East cape about what the defense forces did for them ? The Government has virtually no other resources to use. Our Defense forces are bleeding experienced people as they are so under resourced. The resource we have is supposed to complement tho

Both voltage and temp at cell level; "(b) Each lithium ion battery shall be provided with a battery management safety system (BMS) either integrated into a battery pack or as a separate component located adjacent to the battery. The BMS shall continuously monitor the voltage and temperature of each cell in the battery. (c) All charging sources shall be automatically disconnected by the BMS when voltage exceeds the manufacturer’s recommended maximum. (d) All connected load shall be automatically disconnected by the BMS when the voltage falls below the manufacturer’s recommended m

Take the ply ones in to acrylic creations - they will make new ones for a very reasonable price...

Be careful of quoting installs that don't meet ABYC or AUS/NZS regs. The stumbling block for most drop ins is that they must have both visual and auto warnings before switching off the batts. Bluetooth units can't do this - or at least any Ive seen. If you look for a BMS with CAN bus (or any external coms) then you can comply...

Any time. Sometimes even newish ones - I had one brand new one that looked fine, but wasn't - the rubber, I think, was moving around the metal inner it's mounted on, but only under load....

Electrical fires are one of the most common causes of fire on vessels like ours. Have a plan - You MUST be able to turn off the batteries, or the fire may re-ignite. Extinguishers in service and at multiple locations. 1/Shut off batts. 2/Shut off air and fuel 3/ use fire fighting systems, installed or hand held. Hopefully all this while another crew member issues a mayday, and another gets the raft ready... My maritime fire fighting course just confirmed that you are unlikely to control a serious fire - get ready to get off!! Oh, and if you have a race yacht and it's a lithium batte

Here is a quote from the standard: “This Standard includes a statement that its requirements do not apply retrospectively”. Page 4/114, AS/NZS 5601.2

I’m with Nautical insurance, underwriter is vero. Island Time is Sept 88. So I got the request for “survey”. Read the request carefully. The broker (Nautical) sent the forms with the policy renewal. It’s NOT a real survey, and did not require out of water. It’s a condition report, and can be done by a boat builder, surveyor, (and maybe some others). I got a mate who’s a boat builder to complete it for me. It did NOT ask for a gas cert ( which would be a problem) just that it was in good order and complies with nz regs. Which it did at time of install (but not with current version - that’s ok,

Yes.
