Hole in anchor fluke..

[vertford]

I have scraped alot of rust/paint of my anchor today and one large chunk came away. The whole to leading edge seems very thin so I assume this is sign of something worse to come.

Time to retire the old girl?

Looks more like a not very CQR?

Nah it's an australian (or is it Rocna problem not yet aired)

If the shackle and shank are ok and it still digs in and holds, well, it is still working. If you only anchor to fish or have lunch then you will be aware of what is going on, if you are over anchoring over night and wish to sleep soundly, ......

 

[vertford]

CQR and other fluke seems as thin, but no hole yet. Shank seems sound.

Maybe one option to file this hole out and smooth the edges?

Would like the option to have a lunch hook and an overnight hook combined?

Buy a new one. Tidy up the old as a spare...

I can't believe that is a genuine cast CQR! How did it rust that much?

Genuine CQRs are forged. Copies such as Claw are cast. The corrosion appears more like what would be seen on a casting.

If one part of the anchor is so badly corroded it might be assumed that the rest is similar? In which case the structural strength could be compromised. Dump it and buy something better, like a Delta.

I bow to superior knowledge, but I have seen bits of cast iron that have been burried for years in better condition than that! The bits of plates off the Gt Eastern dug out of the mud on Rock Ferry shore are in better condition after 100 years on the sea bed. I wonder if it has been stored touching something that caused electrolysis?

That would depend on the terms of the divorce settlement. But I would replace your anchor.

 

[vertford]

Thanks for all the input. The view seems to be a new one....

My experience of Chinese cast iron in some shackles is that they just collect a load of old tin cans and the like;melt them down;cast them and then dose the resulting product in a very shiny hot dip galvanised zinc which fills in all the porous air holes!-I was horrified to see the actual steel once the poor quality galvanising got washed away!
As for properly produced iron it can last for a long time-remember forged Low Moor iron plates from the foundary on the edge of Bradford,Yorkshire was used for many years in preference to steel for below water ships plating which is why boats like the SS Great Britain still survive intact.

Cast iron shackles?

Cast steel, not iron. These cheap, cast items are made by small companies in the Far East, probably melting scrap in cupola furnaces. The source metal is old car bodies, broken ships, tin cans and suchlike gleaned from dumps, whatever they can get hold of. The resulting composition is almost certainly not measured, could have carbon content anywhere between 0.2 and 0.8 with tin and copper as impurities. Sulphur and phosphorus could be anywhere.

Standards for anchors limit carbon to 0.21% to avoid brittleness. This is clearly not true of the fractured anchors seen fairly regularly. I have several photos of Bruce copies in this condition.
