Our current Gas Califont installation doesn't comply with the CAT1 regs and its time to sort it out. We don't have anywhere good to mount a califont that would comply so I'm thinking its time to change to engine/240V heated hot water cylinder setup.
It'll be connected to Yanmar 3YM30 + likely to be heated with with 240V using excess power from our 1.5KW of solar + 3kw inverter.
I'm after recommendations of good brands and ones to stay away from.

I think the Piedys are talking to Yachting NZ directly about a class dispensation for lifelines, as the safety they provide can more practically be achieved with harnesses, tethers and jackstays.
I think it would be awesome to have a fleet of Piedys sending it up each year. The bay will definitely know when they arrive!

We have 2 x Yanmar 3YM30 in our cat and I'm due to replace the stupid yanmar exhaust mixing elbows that seem to last only a few years. I'm looking at the HDI ones rather than the Yanmar one as I hear good things about them.
We currently have the high-rise mixer style but I don't think we need them anymore as we have changed the rest of the exhaust system.
Original Exhaust system :
- High Riser Mixer (no anti syphon fitted. Mixer head is about 150mm above waterline)
- Wetbox in bilge
- Exhaust hose then looped up about 300mm above waterline
- Hose ran down to outlet about 100mm above waterline
- Marked as pink on pic below
I was nervous out how low the loop was, so I changed the system to (new loop in green on pic below):
- High Riser Mixer (no anti syphon fitted. Mixer head is about 150mm above waterline)
- Wetbox in bilge
- Exhaust house then loops up about 1000mm above waterline via another muffler (only really used at a 180 degree bend). Marked as green on pics below.
- Exit via the existing outlet 100mm above the waterline
I think I no longer need the high rise mixer style as the high looped exhaust stops the risk of anywater coming back up the outlet. I will need a anti syphon device to stop water coming via the water feed. The normal elbow mixers are half the price and half the parts to corrode, so It would be nice to change it I can.
What do you think?

Noticed the Aussies who won the 470 gold hardly pumped the boat at all and still sailed away from the rest of the fleet.
Really? We were definitely watching a different race then. They pumped all the way up the second beat, and it looked to generate about 0.5k boat speed.
The 470 is an embarrassment to sailing based on that medal race. Ridiculous. Yachts should be powered by the wind, not the crew bouncing away to flap the sails upwind and down.

We've moved away from inflatables after slicing open our Southern Pacific 340 on Coral at the Minerva Reef on the way to Tonga. We realized how dumb an inflatable is for offshore sailing in the tropics, where everything is razor sharp (coral, rusty wharfs, etc). It took days and 3 attempts to repair a 300mm long gash, all the time we had to use paddle boards to go shore, or worse - tie up to rat infested docks!
We tried a second hand Delta dinghy (3m long, hard chine, sailing and rowing) hoping it would be a poor mans OC tender but it's not even close. It's awesome as a rowing and sailing dinghy but not a replacement for our old inflatable dinghy. Its not stable enough, can't carry a decent sized outboard and wrong hull shape to be a RIB replacement.
We then found a unicorn - a second hand OC 300 Tender. It's awesome. Stable, light, tough and can carry a huge load. Its light enough to walk up the beach or ramp, yet can carry 4-5 people and all our gear out to the mooring. In fact I've accidently ended up with 7 adults in it once with no issue. It does feel like the las dinghy I'll every need to buy, except for maybe the larger version on day! The amount of bags you can stuff under the sides/front is crazy.
We still carry the Delta as well for summer sailing and rowing fun, but the OC tender is the workhorse, especially when our mooring is 600m out in the middle of the Auckland Harbour.
-
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.

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.

Marine Hot Water Cylinder Recommendations
in TechTalk
Posted
The trials and tribulations of 60 footer life!
The galley tap will be my furthest fitting from the Hot water cylinder, which isn't ideal. I was thinking I might put a valve just by the galley tap that diverts water from the hot water line back to the water tank (just next to the galley), so at least we don't waste a couple of litres of water waiting for the hot water to come through.
The califont is only about 1.5m from the galley tap and it still takes about 1L of water before its hot. We always have some sodastream or drink bottles ready to fill to capture it.
