YNZ and the Inspectors are meeting tonight to review the findings of the Essence report, so you may want to call your inspector today if you have anything you want them to consider or bring up.

Smartest comment on this thread all day - unfortunately I have contributed to a lot of the hot air
In an attempt to steer the thread in the correct direction and back to the issue at hand.
==================
I don't believe that foreign yacht registration should be the first port of call for people wanting to "circumvent" this rule.
NZ yacht inspectors have discretion available to them when it comes to determining if a boat is sea worthy and meets the requirements for departing NZ. They are required to use this discretion fairly and equally, this is set down in the MaritimeNZ rules for yacht inspectors.
An astute owner will be able to obtain supporting documentation from a manufacturer, designer or reputable boat builder, which calls out that the addition of storm shutters would impact the integrity of the boat to an unacceptable level. Said experts will also be able to provide evidence that the windows, their design and structural characteristics make them as strong and as safe as the cabin they are attached too. The windows might even be structural and part of the cabin structure.
There are transparent floors in the sky tower observation deck, some countries have gone as far as to making transparent walkways which support hundreds of people. By all reports these are stronger and safer than an equivalent concrete structure. So it's obviously technically possible to design a window and frame in the side of a boat which is safe.
The issue is that the inspectors will now have to grant an exemption that is directly contrary to the rules. These new rules have left the inspectors between a rock and a hard place. They were able to ignore the issue this year as the rules only came about a month before the start of the cruising season.
I've had some discussions with my inspector about this and his initial thoughts were that he may be able to still sign us off but would have to get a second inspector to check my windows with him, just to cover his ass if something goes wrong in the future. That will only be a short term arrangement and eventually we'll need to meet the rule, making the boat weaker and unsafer in the process.
I know a lot of current Cruising Multis and only one has shutters, and they had them made prior to this as their windows have a significant curve to them and they knew it would be an issue if they broke one.
I don't know where I'm going to store my 9 shutters in between passages. Our current emergency ply window is as big as a single bunktop. 9 of them is going to make that bunk unusable.
-
The change in window rules is a major change for offshore sailing multihulls.
For keel boats the rule changed from "you need to carry shutters" to "you need to have them fitted". For Multis the rule changed from " you need shutters or strong windows" to "shutters must be fitted."
Old Regs:
Nearly all offshore sailing NZ multis have extremely strong windows and a plan to deal with breaking one of them i.e ply the right size ready to be screwed in.
These new regs are pretty unworkable for most of the multis I've spoken too. It will weaken the window frames/cabin top, potentially allow rot to start in ply boats (lots of NZ built boats), add pressure to the windows where they weren't designed for it (think curved windows) and reduce visibility from inside the saloon. One of the things I love about my boat is we can sit on the couch and have 300 degrees of visibility, meaning watches can be mainly done from inside and greatly reducing crew fatigue and safety. Even if we use clear covers, it will reduce the visibility as our windows are already 22mm thick.
Yes, most Multis have very large windows but we also have a greatly reduced risk of sinking, so the risk profile isn't the same as a mono.
YNZ and MNZ snuck in this change with no consultation due the consultative rule change process. I wrote a submission from the NZ Multihull Yacht Club requesting some rule updates, which they accepted, however didn't talk to us at all about this major shift for Multihulls and have been ignoring our correspondence about it since we became aware of it in March.
I'm pissed enough to be looking at offshore registration as I'm now disenfranchised from how the Cat 1 rules and regulations are formulated and implemented. I was a great defender of the system before.

These seem to be the relevant changes to the Moorings section:
-
It looks like its getting pretty crazy there. It's an interesting situation and I'm impressed that all the Govt Departments and Council are not responding to the media storm being created. It helps that this consent has been tested at every level of the courts in NZ and shown to have followed due process. I think that is stopping any wise politician wading in, as they know the the marina won't get stopped.

Interesting situation. I think Martin Robertson has taken over the Mahurangi Marinas yard by the old Cement works, so he gets a nice payout from the land auction and gets rid of the competition?
-
John Hughes could also be a good option as he has a shed on the waterfront in Mahurangi Harbour and is a multihull expert.

We had the slightly newer Furuno Fax30 which displayed the Weather Fax's straight onto the Furuno Chartplotter, but it died last year and I'm not spending $$$ to get it going again. It was pretty useful to know what was driving overall weather systems that Predict Wind gave the very detailed, but smaller forecast for.

You don't realize how big she is till your alongside her in your dinghy and she's as long as the dinghy!

I've got both the IridiumGo and SSB on Lady Nada and I'm glad I have both for offshore sailing. The iridium is the primary means of contact and weather but the SSB is a nice backup. I don't know if I would spend the money on a new radio however if you have one, worth keeping.
I've found a regular radio check-in with Maritime NZ when on passage to be a nice confirmation someone official knows what we are doing and where we are. Its also useful to know/talk to other yachties on passage to know what the conditions are near them. I have the a weatherfax app on my phone that can plug in and decode a weather fax as a backup to losing predictwind via the iridium.
Gulf Harbour radio is a real asset to NZ/islands sailing and SSB is the only practical way to be involved in it. If you haven't listened to them before, you can listen to a broadcast via youtube there: https://www.youtube.com/channel/UCcu-iy7lVF8YiRfXCIBQ28w/about
Also nice to hear the Radio NZ news is isolated places. https://www.rnz.co.nz/international/listen

Off-loading the board is what I do: a quick bear-away synchronized with pulling the board up.
Slowing down is safer though.
/Martin
Having raced cats for years, this is about the only practical method to get them up if underway. The best way is to get them up/down when tacking but often there aren't enough hands onboard to achieve this. If short tacking, then just leave both down, it doesn't seem to slow you down much.
Be careful with GBE boards if your cases aren't well reinforced inside the boat. They really need to be all the way down or at the top of the case, as they are known to break the case if halfway down and the top of the board is in a unsupported part of the case,

It's a personal choice I think. The alternatives are easier to use, come with a monthly subscription ( can be suspended when not in use). The only thing you are excluded from is the ssb nets.
Following Sea is a service that is bridging the gap between Sat Phones and SSB nets.
You subscribe to the right list and get emails from that net sent through to the sat phone. At least that's how I think it works.

That is weird burying sewage tanks...and just leaving them there.
I suppose apoosewage expert will be along shortly advise this is normal practice for Marinas....The tanks are just holding tanks. The wastewater will then be transferred and trucked to the Greenacres site on Waiheke, which deals with the desludging waste from septic tanks on the island.
I'm not sure about water but they will likely tanker it in, which is fairly common for the commercial operations on the island.

I'm guessing this 108yo beauty has no electronics whatsoever?
What is the damage its showing KM?

The Deltas do get a bit squirrely going downwind with a bit of puff. I've tipped mine over a couple of times like that, giggling away the whole time! Lots of fun.
I've met the designer a couple of times. He has a half size Delta on the roof of his launch. Super cute watching his grandkids row around in it.

Don't forget to make your submission this weekend or you can't complain when they raise the speed limit to 18kts, which is the current favored response.
My submission:
"Auckland Harbour is a small waterspace used by many vessels, often not following the expected east/west route of the harbour. 18knots is far to fast for untrained skippers to operate in very confined waters. Many private skippers do not follow the 5knots with 50m of a another vessel and pass within 20-30m at the current limit of 12knots. These skippers will now be passing at 18knots, creating very dangerous situations. Private vessels are growing in average size, meaning larger wakes and more force in collisions. The recent Americas Cup speed limit of 5 knots have shown how orderly and safe the harbour can be with a slower speed limit. Far safer than the average Sunday afternoon with large launches plowing their way up the Waitemata at 12knots, throwing a wall of water out behind them and driving close to other boats. I'd estimate that we have a vessel pass closer than 50m, at more than 5knots everytime we move in or out of the harbour. I recommend 8knots for private vessels, with 18knots allowed for commercial vessels due to them having licensed skippers. Yachts racing should be exempt for the speed restrictions."

You could always swap down to the smaller Yanmar 3ym30AE and SD25 saildrives with the basic dog clutch. This is what we have in Lady Nada (well the older 3YM30 and SD20) and 95% of time is more than sufficient. There are some times when we feel a little underpowered with a big headwind, but that's more just being a little slow than a safety issue. If we had to repower the boat, I'd chose the same engine/SD20. The 3ym30 is a great engine and very smooth.
Big weight saving too:
3YM30AE + SD25 - 160kg x 2 = 320kg
3JE5E + SD50 - 220kg x 2 = 440kg
But then last time we saw you, you passed us while we were both motoring, doing about 0.25kts faster with a little smug smile on your face, so I'm guessing the extra HP is essential

GT Auto Electrix in Glenfield converted my N-type Hitachi alternator to run as a P-type with external charge controller. They were very knowledgeable and helpful.
I've been to see them and they are giving me good advice. Thanks for the recommendation.

Adrian, I thought the idea of a cat was that they redundancies built in
ie two boats strapped together 🤣🤪😜
On 20/01/2021 at 7:50 PM, Jason128 said:So... you have two functioning alternators on your boat, and want a third as a spare?
surely you can setup to charge both sides from one as a backup.Us multihull owners love our redundancy for our redundancy! As the alternator belt drives the internal waterpump, we do need to have some kind of spare onboard in case one throws a bearing.

Saddle (J) mounts a relatively rare for automotive small frame alternators, more likely found on a basic large frame alternator you could look at some thing like this
Prestolite are the OEM supplier for Balmar, pricing is much more reasonable, I guess the difference is not being painted.
Your Hitachi alternator has virtually no work to do, so it will have a long life. The Balmar feeding the Lithium batteries on the other hand will be slogging away and hence is more vulnerable to failure. So my thought would be, if you want to carry a spare alternator, just carry a substitute for the Balmar (and that could be a LN) and not worry about the Hitachi (and what happened to the original Hitachi that the Balmar substituted?). In the unlikely event of the Hitachi failing you could just run some temporary cabling to the starter batteries.
Thanks, That's some really good advice that has got me rethinking what I'm actually trying to do. I don't really need the charging capacity of the stock Hitachi, and I have 3 of them (1 on the engine, one off the other engine and one spare), but the charging capacity of the Balmar is more essential if the sun doesn't shine.
We killed a set of AGMs in Tonga when is rained for almost 5 weeks straight, so no solar, and our generator died (RIP you POS!).
I'll start my research on those Leece Neville alternators as we have plenty of room around the engine.

On our sailing cat we've upgraded one of our alternators on our Yanmar 3YM30 to a grunty Balmar 175a XT alternator, Balmar external regulator and Serpentine belt kit. This system works well and charges the Lithium house battery.
The other engine still has the standard 60a Hitachi alternator with a single V-Belt and only charges the start batteries for both engines and works fine for this, but now I have different belts and regulation on each of the engine, so having a spare alternator is a bit of a pain.
I'd like to upgrade the standard alternator to something with a external regulator so I can carry a single spare alternator that can quickly be fitted onto either engine but I understand the standard Hitachi is N Field and the Balmar regulators are only for P field alternators.
Does anyone know of any off the shelf alternators setup for external regulator with the Saddle Mount, or any good alternator shops in the Northern half of Auckland that could sort me out?

These are the LiFePO4 cells that we have just got for Lady Nada - 8 x Winston 300ah cells to give 600ah @12V. They get some pretty good abuse in this video without catastrophic failure.

A few more photos of NV from last winter in Tonga and Fiji, where we buddy boated with them. The 4.2m draft and small motor (40hp??) limited her a bit and they needed to follow us into most anchorages, with me relay the depth on the VHF to them.
Going into Vulaga, the last part of the reef pass is only about 4-5m deep in Coral and I ended up swimming in front of them to guide them between bombies!
Its not my choice of boat for the islands but they got there and did it! Its since been sold to new owners who are keeping it in Fiji.
New Hull cleaning regs for Auckland - more costs....

One positive aspect is that it gives the Harbour master another tool to deal with some of the boats left on moorings to die, as they now can't have too much growth on the hull:
Every dying boat around my mooring has got a whole reef hanging off it.
