It was a phone conversation with work safe last year that told me the problem was a requirement for a tapered thread valve and the possibility that a tapered thread in a fibreglass bottle would split the neck open. At the time they would not consider a parallel thread and o-ring... I suspect the guy was also worried at the possibility someone might try and use an incorrect thread.
But would love to be proven wrong, or opinions to be changed, I would still like to buy a couple of bottles if I could get them refilled.
If they are still within their hydro life then maybe a filling station would oblige ? a bottle is a bottle if its ISO compliant and its test is current. Seems a fair chunk of the planet is OK with composite bottles so why do we invent a hypothetical risk that is managed/tolerated elsewhere under the same ISO standard ? where is the data/evidence to support their position ? its nuts.

I paid $3250 for a new Roller Furling Genoa a few months back, the material was Dacron and Tri-radial cut, I'm guessing a basic crosscut Main would be around $3000. My boat is a Carpenter 29 which is a little bigger than the Nova but I think roughly comparable in terms of fore Triangle area. If interested I still have the No 3 Jib/blade which has had little use and The no1 genoa (tri-radial Cruising Laminate) still in good nick both sails are hank on though.

The carefully worded press release praising each other from Burling and Dalton has been somewhat washed away by Daltons more recent public comments. Yes the Royal Yacht squadron has done a neat pivot away from Ineos and backed Bens Athena racing as their team. Who really is interested in the cup ? The racing was not of top quality last year (the womens was of far better quality for those that got to see it) I hope the Italians get the venue they have stuck with it all along and are worthy recipients
When it comes to the kiwis winning on the sailing world stage I'm always interested but I'm wondering who Burlings replacement will be ? Presumably they have/will resign Nathan Outteridge although with his talent and Sail GP expanding he might be headhunted.

As predicted AC38 in trouble, Auckland would have been super- though I agree no public government funds should be handed to a private racing team with all the shares held by one person .
Perhaps the government should have backed the Councils money towards putting on the event , rather than topping up the coffers of the defender. Still its all moot now with the challenger of record pulling out and unlikely to be held in the next best place -The Solent . Only Italy and the Arabs now left in the mix for Dalts to sell to....
Unless I have this wrong its INEOS who have withdrawn, Athena Racing, representing the Royal Yacht Squadron Ltd (RYS), led by Sir Ben Ainslie is still a challenger and the challenge of record, not a lot has changed, still the same number of challengers as last time ?

Read the history of the Grand Banks cod fishery. Depressing.
This comprehensive RNZ article encapsulates the political commercial and public tensions over the crayfish resource and fisheries management in general.
https://www.rnz.co.nz/news/national/542412/high-court-rules-2023-minister-s-decision-on-crayfish-catch-limits-unlawful
The point is made that we do have a fisheries act (law) to regulate how the fishery is managed for sustainability, if the fishery is depleted (kina barrens and other factors) ) it implies government and industry are not in compliance ( literally breaking the law ? This is the basis for legal challenges by organisations such as Legasee and ELI (Environmental Law Initiative) with the high court ruling recently in favour of ELI in contending that sustainable fishing had "not been happening" per the Fisheries Act. In summary the High court agreed that MPI and the minister are non compliant. (see the article link).T he judge also made the point that the minister was led into error by his officials, who did not base their advice on the best available information, (read sloppy work)-

I've dived one spot in the pig group for 40 + years. They have come and gone a bit over that time and 5 years ago were in pretty good shape. But after a summer snorkeling in Fiordland I had another look couldn't bring myself to take any. Hopefully the "caluerpa fishing reserve" helps the population rebuild at the Barrier.
When I see divers videos of Cray Nests in Fiordland its like an infestation under every rock, I imagine the gulf was like that once, it must have been incredible. I don't know if its true but I recall hearing about crays crawling under boat ramps at Whitianga in the early 60's then dying as the tide receded and creating an appling pong for ramp users, this was before the export trade apparently.

Great!
Its good news albeit the statement "the closure, starting from April 1, is to allow the lobster population to restore itself" is an admission that past governance of the fishery was a failure with multiple previous governments being equally to blame for allowing it to get to this point.

First time I have heard of LTO batteries, but they seem to be an advance LFP batteries which are pretty good anyway. I found a fire extinguisher for lithium fires, it has some kind of cooling gel extinguishing agent that envelops the battery and costs almost as much as a the battery at $1695+ GST

Assume 40 footer.
Project manage, $5k (consents, contracts, etc)
Tow to shore, make safe, 4 people @8 hours each @ $60 charge rate plus equipment, $2000 labour plus $150/hr towage and platform, so $3.5k
Break up onshore, 3 days, 4 staff, concrete cutting equipment, site safety, loader at $200/hr including operator for 16 hours, truck to disposal, two loads on a large tipper, hourly rate of $250, minimum half day. Disposal fees at $100 a tonne, say 25t of disposal.
Removal of toxics, oil diesel etc
Site clean and restore 4 people 8 hours.
Beer money.
Tons I will have missed, pricing isn't a quote but I would have thought light rather than weighted.
The upper end costings may relate to vessels that had to be scrapped in less convenient locations than a hardstand e.g large vessels stranded on tidal flats or a beach needing to be scrapped up in situ. Another case is when the boat sinks on her mooring, the point at which the dreamer accepts reality but probably can't be found.

My Hull and deck were done with white International Perfection and its approx 15 yrs since the repaint. The "wet Look" is long gone but there is no chalking , I have only ever experienced that when I painted directly over an epoxy undercoat. Solid colours seem to fade faster particularly anything with red in it.

I was at the North Shore station when most of a Townson 28 turned up, to be fair they had removed lead and toxic materials but they were still refused and told in no uncertain terms to sail on out again. Also saw a Harmonic (probably the plug) being burnt on a boatbuilders farm because no one would take it for free .
I'm moored at Shelly Park and we have a few hulks in the river, recently a fellow club member "inherited" one of them. This person was told by the harbourmaster that if he could get it to a certain hardstand location then they would take care of disposal with no further burden on him. (Thats as I understand it in talking to the member)

Nope,that's not the only option.
It's the cheapest, but not the only.
If you own a boat that is truly end of life, you should dispose of it appropriately. Pull it out, break it up, sell reusable stuff eg winches, send the rest to managed landfill.
Trouble is, that costs.
Psyche's proposal is a solution if the cost falls fairly. Owners have to take some reasonable responsibility.
There is an existing model - cars. End of life cars are now (mostly) disposed of by the owner at a cost.
I have disposed of two cars that weren't worth repairing, I called the scrappie and the next day a sliding deck truck pulled up and gave me $250 cash on one occasion and $400 on another (a few yrs later) I'm sure that the scrap value nets them a tidy margin. With a boat there is no such situation presumably because other then the rig, engine and keel there is little recoverable scrap value and it will be exceeded many times by the cost of salvage, breakup and a trip to the landfill. Reading various reports of abandoned boats having to be removed from the "environment" the cost estimates ranged from 30 to 80k, the latter for old ferro hulls which anecdotally are B*tch . Expecting insurance to cover this is an oxymoron , if the owner had such cover the boat would not be a wreck. The AKL Harbourmaster is steadily green stickering (is that a word ?) abandoned vessels and scrapping them although its a slow process. I was at Blackpool yesterday and adjacent to the wreck of Owhiti a GRP SS24 together with a Bob Stuart DD 32 footer have now been removed replete with lead keels but they sat there for two years. The mooring field in the NW corner of Blackpool has a few liveaboards which is another part of the problem since Boats that are somebody's floating home seem lack maintenance presumably because they cant afford it otherwise they would not be living on a mooring. The ratepayer is picking up the tab for this process at the moment but perhaps some sort of levy is the only viable answer. Recent reports from the UK say that old GRP hulls eventually contribute to the microplastic problem too.

There is a Youtube channel hosted by a German couple with a Grand Soleil design that suffered Keel Grid delamination due I think to incorrect placement of the travel lift slings . There was the usual puffed up You Tube narrative while the yards insurance covered the repairs and now they are sailing across the atlantic. The vessel had a deep bulb keel and spade rudder, well call me old fashioned but I just cant see how such a fragile construction can be considered suitable for anything more than flat water inshore cruising, an accident waiting to happen ? or they may just get away with it.
-
The failure of Gunga Dins hull was concerning as I assume it was GRP ? she looked to be fairly "old School" and likely then to be quite solid. Perhaps pounding conditions not only pump the rig and stress the mast base but also agitate sediment/contaminants in the fuel tanks ? Maybe a better strategy then might be to heave to until flatter conditions or bail out to the nearest downwind port.

Normally I wouldnt use an Epoxy paint that has direct exposure to UV but this Durapox looks to be different, its some sort of Urethane/epoxy hybrid, I havent heard of it before, might try it sometime.

This could get interesting, the product you thought you bought and yet the manufacturer changed a critical ingredient without really letting anyone know. hmmmmn.
What could possibly go wrong?
That has Law Suit City Arizona writ all over it.
Pity Crew don't have a legal arm, taking on the shysters and bullshitters is really the last bastion. providing some level of of pushback otherwise the fuckers have won.
I only say that witnessing the almost total capitulation of a democracy due to ignorance and apathy in the USA, please lets not allow that sh*t to happen here.
Did you contact the Altex Rep via the Patiki rd Avondale site ?

Certainly as noticed this weekend Altex No 5 has been watered down lately , having been a very happy customer for 25 plus years I seem to have slime after two months not had that before.....
This comment caught my eye because the performance of Altex No 5 this year has been terrible, so bad I am currently out for a mid season reapplication.
I antifouled in mid Oct and after 3+ months there are barnacles galore including a few Goose barnacles whats odd is that there is none of the usual slime. I hope this is a one off, I'm moored at Shelly park BTW.

Actually that sounds closer. Boats were swapping position but generally someone making a cock up rather than the passing boat being brilliant.
In the previous round ETNZ were embarrasingly sluggish in the pre start but had good speed during the race and recovered well only just missing out on the final
Yesterday I watched the first two starts closely, they were much better positioned in the initial charge for the line (an improvement) yet the boat still looks sluggish in that final acceleration when they are all jammed together, so still an inability to "Pull The Trigger"as the commentator says. Unfortunately they were not able to climb the placings in the race as per Rnd 2.
Slingsby seems to have another gear in the same space and just accelerates off the line like a bullet no matter where he is positioned I'm damned if I know how he does it but its remarkable , its like he is in a different boat to the rest of the fleet.

24 minutes, really?
Yes goes on a bit but then so did the absolutely bizzare incident at Oneroa where the skipper of a fairly large yacht was deliberately ramming boats and demanding their phones, you can see the boat in question at 1:38, it was out of Westhaven. It took forever for the police to come by which time this visitor to our shores and her son were throughly traumatised. The son did eventually hand over his phone to try and placate the whackjob and it was retrieved later by the police at westhaven (they followed the boat back). Apparently the owner thought the world was going to end.
Composite gas bottles

The bottle on our boat is aluminium with a brass neck fitting sold to me as a refurbished unit by Tank Test Laboratories in Puhinui Rd, I have painted it and keep the neck treated with Lanocote but as already commented you would think it would be of equal concern since I have seen dissimilar metal corrosion cause cracks in thick aluminium, particularly cast material.
