  1. Is it true the main financial donor also owns the Tamaki Marine Park and will profit financially if lower priced / DIY competition is removed?
  2. Only if it's voltage is higher. Higher current doesn't mean anything if it is pushing 'uphill' against higher voltage.
  3. the 17.2 v is the solar panel voltage, don't panic. Your solar controller will turn it into something suitable for your batteries, i.e. 14.2v. Short story, the highest voltage source wins. To get the current into the batts, the voltage needs to be higher than the battery voltage. Hence why batts rest at about 12.6 volts, but you charge them at 14.2 (or 14.7 or what ever). In theory, if your solar controller and your alternator have the same charge voltage, they will both charge the batts. In reality this won't happen. I would expect your engine alternator to do all the charging.
  4. What's the name of the electrical conduit, or do you have a link to the supplier? All the stuff I've looked at it way to wobble / weak. Planning out how to build a new dodger, so this would be ideal.
  5. There are several elements I like about it. Artisticly it says "Open 60" bigly, so if you are trying to channel the hard-arsed lunatic shorthanded Breton crowd, you are doing well. I like that it has low visual impact because you've made it out of a clear material, not the classic navy blue sunbrella plonked on top of an otherwise nicely proportioned white cabintop. The size looks practical and functional. It 'fits' the width of the cockpit. The only question I'd have is if it's high enough to work the cabin top winches, and for getting down the hatch without having to bend
  6. If you just want the PVC clear material, the Canvas Company supply it. Shop For Quality Outdoor Fabrics NZ - The Canvas Company Would need to be couriered from Auckland. If you have lots of time and patients, you could hand sew it on. Same gear as a sail repair kit. Or you could get an 'easy awl' that the Canvas Company supply, it has a bobbin in it to speed up the hand sewing loopy bit. I'm mid way though replacing my clears and will try that. I've also been sewing the clears and sunbrella successfully. Rather than drop $1,500 on a pro sewing machine, I'm using a $200 plastic sewi
  7. You would need a separator / clarifier tank on the dredge, with a direct water return to the area you are dredging. The technical challenge would be the size and effectiveness of a separator. You'd need to give up on this whole concept of avoiding any fragments going back in. The whole objective would be to reduce total biomass. Given that tide and waves are moving this around anyway, the whole concept that boat anchors are spreading it is a nonsense. Related to this is the re-growth rate of fragments. I think there has been a load of PR and scaremongering saying 1 fragment can grow into
  8. In my view there are two separate issues here. The anchoring ban is futile. With 50 Ha of it banning fishing and anchoring is a nonsense. Mind you, it's a nonsense if there are only small patches of it as well. Anyway, lets not go over old ground. If there is 50Ha of it, there is an arguement that suction dredging is very much worth doing. Two premise explain this: 1) Suction dredging needs scale to make it both effective and cost effective. If there is loads of it, you can just hover it up all day. 2) We are told the issue with caulerpa is smothering everything and kill of
  9. Spot on raz88, there are so many more elements to making a boat go than just motor size. All you need is a couple of barnacles on the prop and it will go like a sack of sh*t. That is assuming the prop is a well matched size and pitch for your motor and gearbox. The gearbox being relevant as your shaft speed is what makes the prop work, which is completely different to engine rpm. Given the cost of propellers, esp fancy ones like the super-doper folding ones, how many people have put on a new fancy prop (folder) and found either the pitch or size wasn't quiet right, but sucked it up, or ne

    Birdsall Plans

    Was this boat on trademe a while ago (maybe a year or two, perhaps 3) and a fairly rudimentary boat? predating the other Birdsalls like Focal Point, Pterodactyle, Charlatan and midnight express? I see the YNZ boat search has a sail number of 52, but no other info. That would indicate it is fairly old. I'm sure I've seen TM ads for it in the past, which would give a lot of info if you could work out how to pull up an old listing. I got the impression the boat was lacking maintenance back then and would need a full refit to be of much use. Given the age and elements of the design I would ha
  11. You are under no obligation to observe a rahui. Just saying.
  12. Beta engines also use Kubota basis. I've found no problems finding references for spares via various Beta websites via google. Also the local Beta agent, The Engineroom, is very good.
  13. LegaSea NZ The government is forging ahead with support for ongoing bottom trawling despite widespread public outrage at the damage it is causing to the marine environment. Two decisions within days of each other confirm the government is committed to allowing bottom trawling, dredging and seining in inshore waters. Both decisions are contrary to the government’s vision for healthy and productive oceans. Off the back of an extremely unremarkable Industry Transformation Plan that manages
  14. What are you trying to say by posting that BP? Whilst the bill will be introduced to Parliament, it wont be passed before the election. That means it is a big waste of time. Hot air. All talk. On the area protected, of the 17 areas, only 5 are seafloor protection areas. The specific area of those 5 seafloor protection areas aren't given. Two areas are just tweaking of existing marine reserves. That, and protecting 18% of the Gulf means there is 82% available for bottom trawling. Maybe I should be thankful something is happening? 1) Nothing is happening, cause it wont be passed i
  15. Triple of nothing is still nothing. There needs to be a complete ban on bottom trawling across the Gulf. That, and this is just an announcement. Wont be passed into Law before the election. We are commercially catching bait fish, in the order of hundreds thousands of tonnes, and exporting it to the Ivory Coast. At $2.30/kg. But no-one can work out why our snapper are starving (the milky white flesh issue). The only reason they can say dredging and bottom trawling doesn't damage anything, is because they have already destroyed everything. But it ain't going to grow back if they
  16. These two caulerpas are found naturally in Lord Howe Island, Norfolk Island, central and western Pacific including Tonga, and in Australia. In Indonesia and the Philippines they are also farmed and harvested. "It seems that the conditions are getting more suitable for some of these subtropical species (such as caulerpa)," Inglis said. Caulerpa likes sea temperatures averaging above 15 degrees. On the other hand, the warm water East Auckland current that sweeps down Northland's east coast at certain times of the year brought many tropical fish with it. Then they disappear as
  17. When the second line of the article says this: New Zealand's first mainland infestation of the exotic pest was found at Omākiwi, Te Rawhiti in the Bay of Islands on 3 May. It is still the only known confirmed mainland infestation. You really have to wonder about the accuracy of the rest of the article. Or do they not count Kawau and Waiheke as mainland?
  18. NZL20 is being moved. Is being towed by a jetski. In the general direction of Mahurangi at the moment, assuming it isn't going to be scuttled, which is probably not that bad an option. PS, using a telescope to see what is going on, so phone photos are somewhat pointless.
  19. We are possibly talking at cross purposes. I agree with your points above around trying / investigating biological controls etc. What I am mocking when referencing people thinking they can control nature is the tides and currents, the wave action and the ability for this weed to spread by natural means. That is in direct response to this ongoing narrative that it is only spread by irresponsible and selfish boaties on their anchors and fishing gear. Noting that the Waiheke people appear to be the first to acknowledge the tides and currents are responsible for spreading this (along with, in
  20. So, despite Caulerpa being at Barrier for 5 years, and known about by the govt agencies for 2 years, there is no obvious impact from it, based on this Niwa report. No mass die-off's. No collapse of the ecosystem. Just the need for further monitoring. Kina's gonads are different colours all the time, that is the whole issue with harvesting kina. Scolly's are struggling, which is why they closed the entire Gulf scolly fishery, remember? Report into impacts of exotic caulerpa on native species at Aotea As part of our research programme, NIWA is monitoring 18 permanent sites in the affect
  21. Of course. If you want to define 'controlling nature' as getting a bull to shag a cow at the time of year of your choosing. And I'm sure you can stop the tide, as the Dutch built dykes. But in the context of banning all forms of boating - which is what the rules entail - compared to stopping the spread of caulerpa on the tide and currents, I think you're being a bit optimistic in thinking you can control nature.
  22. This concept of being able to stop or control nature fascinates me. A lot of people, including our govt, believe you can control nature. At least with Waiheke the locals have stated ”We believe currents are one of the biggest vectors, along with boats and fishing gear.” While it wouldn't surprise me to see someone from a govt department pass a law banning currents and tides, I think (hope) there is a wider acceptance that we can't control currents. I can't see how fishing gear really spreads this. Fishing gear in this context being line fishing, lures, softbaits, livebaits, stra
  23. They aren't building Penlink just so they can cancel the ferry service. To think so is naïve. I think you will find that AT can't handle the ferry operator. But there are loads of bus operators so they are easier to push around. Hence AT want buses.
  24. From that first link "You had to stop importing and manufacturing paints containing diuron, octhilinone and ziram in 2017". So I suspect these are the changes they made 6 years ago that stopped all of our regular brand AF's from working. I doubt if you purchased anything this week it would have any of these ingredients, as the actual ban on making or importing them came into effect 6 years ago.
  25. This is a common refrain from people who already have warm, dry homes.
