G'day Sweetie, you called?

Fittings for the AQUA7 are around but you need to find someone who knows that their game well. It's unlikely anyone bar a specialist will have the good stuff. We have a range of fittings which are as strong as or stringer than the AQUA7. They include connections and enlarged links. The Enlarged end link fittings do not need to be factory done so they can be retro fitted if you like. You could put them on any chain if you desired.

The galvanising testing had issues as many tests do. In over 2 decades I've ever only seen one bit of Maggi chain rust faster than the one in the test, and that was suspected contamination from the drum it was in. I know of boats with Maggi nearly 20 years old that's been re-galved only once. But then the biggest reason for premature rust is the boat owner often so that's got tot be taken into account in any discussion.

Maggi G70 had 50 micron thickness with no flaking and good adhesion but poor abrasion resistance, while G40 had 185 micron thickness with much flaking and poor adhesion but great abrasion resistance. Maybe the two types are produced by two different plants?

Maybe that's because the A7 isn't HDG, something the tests should have pointed out don't ya think. A lot of what people see as HDG isn't these days. HDGing is bad for the climate they say so many are using differing coatings instead, one Maggi uses is called Zinc-O-met. PWB played with ArmourGalv, Acco has another. Yes Maggi has many plants, it is a big outfit.

I saw drums of 5/16", 3/8" and both types of 10mm and as I recall 5/16" & 8mm are a precise match?

Careful, there is some lining up of physical sizing between the metric chains and the Imperial but not on every size. The most common US 5/16" is a 9mm DIN in metric land, some of the US 3/" are 11mm in metric land. And many " don't match mm at all.

Both 10mm chain types and the 3/8" were retailing @ $3.50/ft plus Florida tax, so around $3.70/ft. for cut lengths, presumably less if you wanted a whole drum - the 3/8" & 10mm were definitely in 400 foot drums and I think, but can't promise, that the 8mm - 5/16" chains were in 550' drums.

Ha fancy that, that price is almost identical to what it goes for down the bottom of the world. Maggi tend to pack in a length rather than weight but then the US operation made working differently. A 'drum' of 8mm here is 400mts (1312ft) or 200mts if 10mm (600ft), not many buy by the drum In fact in NZ we just buy whatever length we want and don't do any of that drum or weight thing. I've never once heard anyone say 'Deploy 88kilos of 8mm chain please' but I have heard 'chuck over 62 metres then grab me a beer, thanks mate' so we can't understand why so many buy/sell by weight.

Peerless does not list breaking strength of 5/16" HT on their website (that I could find easily). However, Maggi and Peerless/Acco both show a working load limit of 3900 lbs for 5/16".

Wasn't the Maggi chain previously listed as having a greater working load strength than Acco? Something over 4000 lbs.??

In the US, G40 chain WLL is calculated at a 1:3 of the BLL. Everywhere else in the world it is calculated at 1:4 of the BLL.

So if you look at Maggi 8mm chain, for example, you will find this 1:4 ratio.

With Maggi's new imperial size products in the US, they have adopted the US 1:3 measurement. So the 5/16" chain looks on paper to be lots stronger than the 8mm chain.

The best way to compare chain is to look at the BLL - that can't be messed with.

A magnificent call there fella, and you are right on the rest of it.

Here we use 5:1 on the AQUA7 chain, 4:1 on the rest. The idea with the 5:1 is most who buy A7 use massive anchors and tiny chains so to help save them from shock load issues we've tweaked the design margin.

So with the Maggi AQUA4 8mm we have a 4,000kg break and a 1000kg Working load. If that is the AQUA7 it's 7,000kg break load and 14,00kg Working. 11,000 with 2200 on the Aqua7 10mm and 6400kg with 1600kg on the 10mm AQUA4.

Note to our American cuzzies - 5/16" is close to 8mm but it's not identical so the loads will vary slightly, same applies with the 3/8" against the 10mm. Also note the ACCO G70 isn't one, it appears they get a G70 then galvanise it so it's only a G60/83 there abouts. The Maggi AQUA7 is a true Grade 70.
