They use nets though - usually with dingies to position them.

I thought there was a ban on trawling (netting) from Port Hacking to Wollongong - with an exemption for longliners catching bait.

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.

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

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.

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

You're the only one raving, you have just repeated your same mistake, ie the logical fallacy of whataboutism.

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.

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/

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.

Yes rated and not S/S. Doesn't that tell you something?

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).

Or that there was a post here showing an anchoring set up which included a stainless steel swivel and clips.

You can't have read my well researched links then Their whole point is that stainless steel behaves differently to gal steel.

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)".
