Quality

Probably most of you have read Practical Sailor's test of mooring chain. There are obvious variances in steel quality and galvanizing. Having said that, just because you pay more doesn't mean you are getting better quality. I wouldn't hesitate to buy through McMaster for occasional anchoring needs, but I would tend to be more dilligent if I was spending lots of time on the hook or on a mooring rig.

If you check the spec & price from 1st Chain Supply for 5/16 G4 you'll see that the link length is different than the McMaster-Carr spec - i.e. inside link length 1.15in vs the 1.03in of Acco from 1str Chain (ISO Short Link, which I use on my Sprint windlass with 5/16 G4 gypsie).

At the time I bought my 275ft 1/2-drum (3 years ago, for a lot less) they were the best price - including shipping, which is a major consideration for 300lbs of chain.

I bought 30' of 5/16" gavanized(not zinc coated) from Lowe's. I left my boat anchored for a couple of weeks now the chain is a bunch of rust. All my new 1/2" nylon rode had algae and barnacles growing all over it.
How long does galvanized chain usually last before you start seeing rust?

Information is hard t obtain. I am sure that there are not many places making chain. I bought some lowes chain years ago and it looks OK. Used it in saltwater and freshwater. Bought a new anchor rope with chain from Ebay . It looks pretty good but I have not used it yet. What really angers me is paying top price for normal stuff. I remember buying an O-ring from a diveshop for $2. The same O ring was 15cents at the hardware store next door. The owner of the shop confessed that the O rings in his diveshop came from the hardware store!!!! We pay a lot for "trust" unfortunately I fear that our trust money is wasted.

I am a cheapskate when it comes to these thigns. But you have to be 100% that the oring isn't made to endure salt water and the others are not, just as an example. I didn't buy the orings for my groco strainer from a marine company for that very reason though.
I think people are willing to pay more for the peace of mind instead of doing research or experiments. As a testament to that...I give you West Marine.

C'mon fellas, comparative shopping shouldn't be left up to our

wives alone when food shopping! :)

You don't have to be a cheapskate. Why EVER buy something for $$$$$$ when you can find it for $???

A little history for new-to-boats boaters:

West Marine, however difficult they may now be, started something 20 or more years ago that benefited us all: reasonable prices with stuff ALL in ONE PLACE that all of a sudden, instead of being hidden in some dark, hard to find chandlery, was made "public." They deserve a round of applause for making what we now consider boating possible by making the products accessible. They lowered prices on a lot of stuff over the years. Remember when a 3 channel crystal VHF cost $500??? also, remember they publish those handy dandy useful Advisors, FREE, which contain a lot fo basic information for starter boaters, as well as some very high quality electrical systems guidance. They also opened stores near marinas - wow, what a concept!

The ONLY chandlery in San Francisco in 1978, for instance, was located in the heart of the financial district, hidden down a dark alleyway. No place to park, nowhere to load, hard to find, limited stock, you name it. Now, WM has gone to the dark side, but I remember when they actually, hear this, had folks in the store who knew about boating. No longer - it's just lowest price for labor, highest price for goods. Times change, get used to it!

So, now my favorite boating store is no longer WM, but ACE Hardware. And I've suggested that many times to folks on this forum.

If you buy cheap chain, it's possibly a VERY unwise "investment" or savings, because your ENTIRE boat could be lost. Pound-wise, penny-foolish is NOT a new concept.

So, make use of the available resources on the internet, which didn't exist only a few short years ago, and learn about materials, find others who've gotten good deals for PROPER equipment, and buy prudently.

Nobody forces you to go to WM, and they still have some relatively good bargains: cleaning stuff, or use "green" products or your local hardware store. Everyone who's owned a boat (and not a mega-yacht) should have learned by now how to find bargains. But remember: not all sales are bargains and not all bargains are sales (or good for that matter).

Even us guys can now comparative shop!:dance:

I like to do my homework before I buy anything. I don't mind paying extra for quality but I hate paying more than I have to for equivalent products. I have done a little homework. They are close in price, $3.18/ft for the industrial chain and 3.49/ft for the marine chain. The less expensive chain links are 1/8" longer and it appears the marine chain has an extra heavy hot galvanic coating. There is really no way to know how much thicker it is because there are no spec. for the process listed. I can only assume the extra thickness is worth the extra money.

If you have a windlass, the particular size of the chain links becomes EXTREMELY important.

A careful reading of the Campbell listing indicates the marine chain as having shorter links and a bit more weight per foot. I expect that the thickness of the galvanized coating is about the same.

I believe the better marine grade chain has a heavier zinc coating than regular industrial chain does. It certainly takes far longer for the zinc to wear through given similar usage.
