This is a well debunked myth and does the rounds every time there is a big eruption. published scientific estimates of the global CO2 emissions for all on land and submarine volcanos “lie in a range from 0.13 gigaton to 0.44 gigaton per year.” This is a fraction of the CO2 produced by human activity. In 2021, the global CO2 emissions from energy combustion and industrial processes alone reached a record high of 36.3 billion tonnes (or gigatons, GT), data from the International Energy Agency (IEA) showed ( here ). A graph by the IEA tracking the increase of emissions since 1899 is vi

The thought of a leak of coolant into the fresh water inside the cylinder really scares me. Coolant is lethal in small doses, 80mls and you're done for. Perhaps I am over thinking it as I have never heard of this happening - but it's not like I have never heard of corrosion on a boat happening!!! Hence the over thinking We used to have a cylinder that was heated off the salt water circuit, but that was with a raw water cooled engine. I am not sure if the salt water side of modern engines with coolant/raw heat exchangers would get warm enough? I still have the cylinder if anyone w

Self insurance isn't really an option, unless they have several million sitting around that they can tie up in escrow... Insurance would be more about 3rd party than protecting the owner against loss. This could run in the order of perhaps $1M if they were to say wreck their boat on the Poor Knights. The legislation allows customs to ask for whatever documentation they have internally deemed necessary. Proof of insurance has always been a requirement for boats over a certain GT - maybe they have decided to just apply this to all boats? It would be best to have a conversation w

You could get an aftermarket stainless one. Just search for d2-40 stainless exhaust mixer. Here is one. https://www.marineenergy.com.au/products/volvo-penta-v878-stainless-steel-mixing-elbow-replacement I had a custom riser made. But it cracked after an estimated 150 heat/cool cycles which was pretty disappointing. I had it repaired, but obviously the stainless is weakened so it gives me some cause for concern. I have heard that the cast one's corrode and the stainless cracks. I have kind of reached the conclusion that these things are disposable items. Also chec

Just received this email from NZMHYC. I will get back in my box, they obviously tried pretty hard to avoid a clash while getting their new classic underway. And it seems there are some future harbour events that they want this to be a part of which played a role in the conflict. Whilst we were very excited to bring you the news of the inaugural Harbour Classic (Saturday 1st April 2023), we recognise this is on the same weekend as the Altex Yacht & Boat Paint Auckland to Tauranga Race (Altex A2T). The Altex A2T race for cruising yachts starts at 1000hrs on Thursday 30th March with th

All races are cat 5 at a minimum. Cat 5 (and 4) is self declared. The skipper does the inspection themselves.

A2t is Cat 3. Which is the same as coastal classic but with a life raft, and most coastal boats carry a raft anyway. So if you're a coastal classic boat you have to choose one over the other. We'd do both if it was an option. It's always less about the race and always more about the destination. What makes coastal, a2t, kauwau night race, ssanz anzac, (and now this), so attractive, is the after event. 37 boats entered a2t in 2021. That's a lot of boats with phrf having to choose. Hopefully in future years it won't conflict. It is a great idea. But given a2t has been on the

Smack bang in the middle of the Auckland to Tauranga. Which is a great race where many boats with PHRF could also be. Such impeccable planning.

You can get an attachment that loops around the furled sail. Particularly useful if you have a furler, cause what happens is people can reduce sail area over time as the wind increases, finally you're down to a handkerchief in 40knots and it is suddenly impossible to unfurl, drop and hoist a storm jib in its place. I assume if your staysail is on a furler it's removable? In which case you could have a storm jib in it's place with a Dyneema luff cord so you can crank it on tight. But that would depend on if your boat performs with the centre of effort moved aft. Out storm

What are you using to drive the rudder? Does that piece of kit work? In my limited experience that error is the result of a failed rudder drive.

The 2013 concept plan, did not include an option for closing the hard stand. Concept 1, 2 and 3 were announced in 2022 and were "updates" to the 2013 plan. So Concept 3, closing the hardstand, was announced in early 2022, (or maybe late 2021).

As a side note, I recently discovered that the callsign and MMSI actually belongs to the person who registers it and then that person can associate them to a boat. When you sell the boat, the callsign and MMSI number don't go with it unless the owner transfers them for a $50 fee.

Buying one might be an option. I bought one of these recently, very cheap and a nice tool to have in the tool box. https://www.trademe.co.nz/3906863326 Unfortunately I have no idea where it is as I am between storage containers so can't loan it to you.

Thanks. Hopefully Auckland Yachting and Boating Association are in a position to take it through the courts. Please share with crew.org if they have a way that we can assist financially to the cause if they plan to proceed with a challenge.

Did they vote on this? Or what was/is the outcome?

That's Hydrogen Peroxide. I have often thought about using that but have never been able to find any good sources for what concentration to use. Interestingly that product is 7.5% while food grade h2o2 is 33%. It's also stabilised with silver so it will hang out in the water indefinitely until it runs into something biological. It's amazing the crap we drink... Water is anything but H2O I will look at this. Thanks.

I once had a valise repacked from a suitcase shape into a rollbag of the same volume. Might be an option to get it repacked to fit into the locker?

The 0.5 micron filter results in a slower velocity. Which means more contact with the carbon which means less Chlorine. Jabsco don't publish the filtration size of their filter, but an educated guess puts it at 10microns. So the 0.5 also catches any smaller nasties that the Jabsco misses. The 0.5u is also too slow for general use.

Carbon filters "remove chlorine" via a chemical reaction. Free chlorine in water is HOCl and OCl-. Which is pretty much where my knowledge ends.... So taking a guess, the carbon gets oxidised into CO, CO2 or COO-. And we have a chloride and hydrogen ion left over... I have no idea what happens to the chloride ion (Cl-)... It's a salt, so I guess we drink it? And I suppose the H+ joins the rest of the hydrogen in the atmosphere.... Or we drink that too and fart it out. The more the carbon oxidises the more blocked the filter will become, I sppose a lot of that would end up ba

The pravailing wind in Auckland for the last 6 months on race days has been N/NE. We've had more Code 0/jib starts than any other season I can remember. Takapuna Beach sand is all but gone due to the continual north-easterlies. Not very scientific, but Niwa's prediction has been fairly consistently delivered from my perspective. ------------ La Niña weather conditions, characterised by predominant north-easterly winds, had made a “noticeable impact” on the beach. https://www.stuff.co.nz/environment/300734858/sand-levels-at-popular-auckland-beach-at-their-lowest-sinc

On the boat side. I have a strainer before the pump, a Jabsco filter after the pump, and a 0.5 micron filter on a dedicated drinking water tap. The replacement jabsco filter is now rediculously expensive, it was $54 last year, so I will probably replace it with something more cost effective as I can get a housing and a filter for less than a replacement jabsco filter. I don't see any value in a fixed installation shore side filter. Maybe if I had a water maker and needed to keep chlorine out of the system. I know lots of boats and RVs have them.

What do people do to sanitise their water tanks? Our tanks (2x200l) are built in part of the furniture structure. They are fibreglass, either polyester or epoxy and I was told they were oven cured. I put one of those USB endoscopy cameras into the tank a few years ago and it wasn't clean by any stretch of the imagination. It is full of baffles, so cutting it open and adding an inspection port for cleaning isn't a option. Our water was gross when we got the boat. So this is what we do now. Each year, about now. I remove the filters and fill the tanks and plumbing with 50

Still in force. And they made it tougher. You used to be able to get an permit if you had ample fresh water supply to clean down your chain/anchor. Permits have now been removed. 47557-Exotic-Caulerpa-Revised-CAN-expiry-April-2023-AHUAHU-AMENDMENT.pdf

Firstly check for parasitic loads. Anything attached to the start battery that shouldn't be. The VSR is obvisouly a parasitic load, but that should be the only one. Then check the battery... (1) what's the voltage on the start battery immediately before cranking when it has this problem? Less than 12.4v then the battery wasn't fully charged, or if it was it isn't holding charge. To confirm this, turn off the shore charger and let the battery rest for 48hrs. Now check the voltage... Should be 12.6. (2) What voltage does it drop to during cranking? (you will need an

Does your vsr go both ways? Eg if your 7 stage charger is plugged in, does the vsr let it charge your start battery? It's curious that you are only having this issue when you are out. Eg you have not indicated that it happens after the boat has been sitting at the marina for a couple of weeks.
