  1. They use nets though - usually with dingies to position them.
  2. I thought there was a ban on trawling (netting) from Port Hacking to Wollongong - with an exemption for longliners catching bait.
  3. Well you got plenty of comments liking your innovation, ie it didn't seem to stop anyone. Zoran's set up was actually on the same topic - anchoring.
  4. That's the only paragraph that is on topic. The whole point is that the strength rating goes out the window once corrosion sets in. Look at this example. It has a SWL of 1350 kg (same as Zoran's swivel) and is made of 316 stainless which you are going on about: https://www.fsc.com.au/wp-content/uploads/2016/07/Anchor20Swivel20Report.pdf
  5. How can not posting on a topic be a diversion? You have to actually post something at least for it to be called that. PS: I am not too worried about what my anchor gear looks like.
  6. I didn't have to search very hard actually. You are welcome to provide counter evidence of more failures in anchoring gear with gal mild steel (good luck with that). As I keep having to point out bringing up other uses is a diversion/ the whataboutism rhetorical fallacy. Anyway here's another informative article: https://www.practical-sailor.com/blog/is-stainless-steel-really-the-best-metal-for-use-in-an-anchor
  7. You're the only one raving, you have just repeated your same mistake, ie the logical fallacy of whataboutism.
  8. This is just argumentative (more whataboutism). You know perfectly well what i am saying. Ie that S/S is more likely to fail and that corrosion in S/S is more likely to lead to failure. Firstly because the signs of corrosion are more subtle in S/S and secondly it does more damage to the strength and integrity than in the case of gal steel. This is only made worse by the much lower working strength to start with when you compare the ratings.
  9. I'm not still on about about 'NOT using marine grade 316 S/S fittings and fasteners on boats used in saltwater?' , etc. I have never said anything about S/S not being suitable for any of the applications you mentioned. My only objection is for anchoring tackle and this is supported by links which include documented failures. . Saying it (your attribution), over and over again does not make it any more credible and is just a diversion from the actual argument. Ie there is a lot of whataboutism going on here: https://www.dictionary.com/e/whataboutisms/
  10. The Suggested Work Load is 290 kg (and this is the only figure you need to pay attention to). Here is what he said: "I have supplied manufacturer data showing that the snaps I use EACH have a suggested work load (SWL) of 290kg and a breaking strain (BS) of 1160kg. Two snaps combined in the way I use them have an SWL approaching 580kg and BS approaching 2320kg (my whole rig with 2 crew weighs 1972kg)". The 1350 kg figure (a 'rating') is for the swivel not the snap so you didn't even get that right.
  11. Yes rated and not S/S. Doesn't that tell you something?
  12. You haven't actually added anything new Zoran. And you haven't really explained away the documented failures in my links as well as the plausible explanations. The whole point is that S/S is more likely to be weakened by corrosion and without warning. And good luck seeing what is going on on the shaft and pins of your swivel seeing that they are hidden from view. Also they are also likely to absorb and retain water so in fact they can be exposed to water for a long time. Plus your anchor gear might be sitting in a wet anchor well for lengthy periods. And you are not really 'oversizing' when your snaps are only given a working load of 300 or so kg's whereas a gal D shackle rates in the tonnes (1-2 typically). Engine and bollard bolts are not comparable. For a start the transom or bow takes much of the strain, you have 4 of them, they are a different component with different rating, they are not immersed as long, etc. PS: S/S shackles are not recommended for recovery situations(4wd).
  13. Or that there was a post here showing an anchoring set up which included a stainless steel swivel and clips.
  14. You can't have read my well researched links then Their whole point is that stainless steel behaves differently to gal steel.
  15. Here's an article about the use of swivels and how they are a weak link. Also they recommend against the use of any stainless steel components: https://www.practical-sailor.com/sails-rigging-deckgear/anchor-swivels-caution-required "One of our concerns is material. Stainless steel, in our view, is to be avoided for any load-bearing components in the anchor rode. (For more details regarding our aversion to stainless steel, see our special report, Marine Metal Warning PS February 2007 online)".
  16. You can't have read my links then.
  17. Yes, well at least you have dropped comparisons to tilt rams and propellers. I'm not sure why you want to drag up different and unrelated applications when I have shown documented failures in S/S anchoring components, due to corrosion. Ie absolutely you can have different views for different applications.
  18. Make sure you lock S/S shackles as they are more prone to coming undone (see my link on shackles). PS: Oversizing won't compensate for failure due to corrosion in S/S parts, that's what my links were about. It can result in almost zero strength and unexpected failures due to the lack of visual signs. And your anchor is as safety item in the event of engine failure.
  19. Well independent advice is valuable, ie manufacturers are not likely to malign their own product. There is another discussion here so he is not exactly a lone voice: https://www.cruisersforum.com/forums/f118/force-anchor-swivel-critical-failure-71238.html Yes you will have to replace gal chain and shackles every now and then but they are so cheap and easly to change over you can treat them as a disposable item. Obviously things like propellers, trim and tilt etc are not as easliy replaced and the forces are different (eg aluminium and even plastic are used for propellers and you wouldn't even think about using them for anchoring tackle). The principles are the same whether you are anchoring a yacht or fishing boat as far as i can see. The former might spend more time anchored so the problems might show up more often - but that gives us something to learn from.
  20. Well the article seems to come down against S/S chain and also swivels. There is more on the latter when you look at the link: http://www.coastalboating.net/Features/Editorials/swivels/index.html It says the swivel is an uneccessary weak point. It also points out that with most designs the shaft is hidden so you can't check for corrosion and also it is likely to collect and retain moisture.
  21. I think the explanation that some of it (the eastern section staring near the tunnel) is now a toll road/ no cash back.
  22. If you mean the cash back scheme it's gone isn't it? It's now a Toll road. You still get a notice on MyEtoll and you can then claim it back (the difference). I didn't see anything about it not coming into effect by Nov. Unless that means you have to wait until the quarterly notice is out by then and then you can claim back for the quarter.
  23. New Signing has a point. Stainless steel is more brittle than mild steel. Also it can corrode in a low oxygen environment or if constantly wet and can lead to catastrophic failure even though it appears to be in acceptable condition. There is a good summary here: http://cruising.coastalboating.net/Seamanship/Anchoring/MetalsUsedinAnchoringTackle/index.html
  24. There are aftermarket, non standard one available.
  25. You have ignored my point - it will be easier just to deal with it. I can provide some references if you like. Also where did you get those figures from? PS ironically much of the ageing bulge is the result of past waves of immigration.
