A B&G WS320 wireless wind MHU with a NMEA2000 interface is $1009 + GST....

Ok, that's a much better heading sensor than the usual ones on an AC12! So Yes, a NAC2 or three would be an improvement. However, I have had customers complain about them as well, and also H5000 pilots. All the pilots need to be setup correctly, usually by more than just autotune. With the AC12 and the NAC series, the low and high speed settings can be used to have normal and running settings, rather than low and high speed. S turns are often the result of too much rudder gain, but can be wrong counter rudder settings as well. There is a pretty good description of this and how to set

This is from B&G. So if you want motion correction, has to be a Hercules or H5000...

Yep, fair enough, but I'd say that even once a second is plenty for start line maneuvers - there is a LOT of calcs goin on for that, all at sub second intervals, and how many course changes can you do in a sec anyway . Navico support has become less efficient since the Brunswick takeover...

Pretty much if the accuracy of your existing systems (when working!) was fine for you, then you don't need a processor system. If though, you want to know the exact wind angle on the next leg, you want or have polars, and you have sail crossover points to within a couple of degrees and knots, then more accurate info will make you sail faster....

Anyone want a good 1050? A mate is selling his https://spboatsales.co.nz/1994 Elliott 1050/

Just a side note - how do you know what the triton edge processor actually is? I don't and its not in the published data that I can see? Also, the current model 3d Motion sensor is N2K certified, has a standard micro C connection, and the B&G system builder lets it connect with the Triton Edge, so I suspect the answer will be it works fine. For most people no processor is required. For serious club racers The Triton edge is easier to configure and less complex than the Hercules, which is really designed for pro navigators in race teams. The WTP3 processor is for linux geeks...

Hercules have been around for 3 generations now. Just to confuse the issue, the H5000 had a model called Hercules (and 2 others), and now the replacement for the H5000 is called Hercules. Don't ask me why, it's confusing!! Sorry I cannot currently answer the question about 3D sensor on a Triton Edge - I've only ever done them with the H5000's. I have asked B&G/Navico for an official answer, and will post here when I receive it. If you are using a AC12 or 42, the main issue in steering downhill is a fluxgate or (slightly better) a RC300 - which is a rate compass, but still a f

AC12 is old tech. The wind algorithm in the newer NAC series is heaps better. The B&G systems only do basic wind calcs if you don't have a CPU (Triton Edge or H5000 - Now Hercules). The Triton edge and H5000/Hercules would expect to have a Precision 9 (Roll, pitch, yaw, heave, heading, rate of turn etc) AND a 3D motion sensor (to get rate/speed of roll and pitch) OR a 3d motion sensor and a gyro, so as the CPU can remove the masthead motion in wind calcs. The wind calcs are much more sophisticated and configurable in these than the basic units. Think about this - as the mai

Agree but surely an appliance that is not leaking, and functioning as designed, and has been running for years cannot be deemed "unsafe", I get the opinion issue...

So wind speed depends on angle. 12 knots (true) at 60 deg apparent is fully powered up. Down deep, say 150 app, can hold it to about 18-20 - but don't round up!! Cant remember the cloth weight - ask Booboo - he made it! In about 18 knots true, and 150 app angle, boat speed is about 10 knots, so radical wind speed over deck if you loose it and round up!

So, perhaps a joint effort in construction of a response? This section gives an answer in my view; "Certifying Gasfitter to require the installation to :- Be Gas Tight Compliant with the codes at the time of installation. Any unsafe gas installation or appliance be isolated, and the consumer notified. Should any work be carried out to the gas system as the result of either an inspection or testing of the installation, then the installation of the boat or vessel and parts of the system do need to comply. For example, a gasfitter has te

Well, here is the response; Good afternoon Matt, Thank you for contacting the Board regarding LPG installations on Boats. If a gasfitter is required to issue a Gas Safety Certificate for any existing installation, this usually starts with a visual inspection of the installation followed by a gas pressure test. You are correct in stating that the standard includes the statement that compliance with AS/NZS5601.2:2013 it does not apply retrospectively, it does not take the responsibility of the Certifying Gasfitter to require the installation to :-

hands down a Norths A2. Replaced an MPS. Use it all the time, 150deg up to about 60 apparent. Way more fwd power and less heeling than the old mps, and easy to handle solo - its in an ATN sock, but probably go for a top down furler now...

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...
