If the shank is supposed to work as a beam, a tiny hole along its central line bears almost no contribution to stiffness.
Anchor shanks more frequently bend in the horizontal direction. A hole in the centre of the shank will make this more likely.If the shank is supposed to work as a beam, a tiny hole along its central line bears almost no contribution to stiffness.
Reticular shanks for next next next gen anchors?

as in post #38 ... the kink in the shank is exactly where the hole was drilled.
Structurally, why? Sorry, no way. In other words: with a tiny hole, they will bend horizontally with a very marginally higher load.
Or ask Fortress for their thin flat shank, or most anchor makers why they do not maximise shank resistance modulus in 360° direction and decide to go for flat shanks. Have a look at old CQR shanks, like a railroad beam section. )
The whole hole story was just to get Mrs Baggywinkle to agree.....there’s only one reason he bought that anchor.....it’s shiny.....really shinyStructurally, why? Sorry, no way. In other words: with a tiny hole, they will bend horizontally with a very marginally higher load.
Check resistance modulus whatever neutral axis you want, the variation in stress will be well inside the manufacturers safety factors
If shanks bend more in horizontal direction, they will very marginally bend more if they have a tiny hole along the neutral line. Will a central tiny hole change anything with a side loading of a shank? Very, very marginally, say nothing: it will bend with a very tiny % lower load. Physics, not opinions
(apologies I do not have the correct technical terms in English, too many languages
That’s a good strategy......’Baggywrinkle’s wife lets him have a new anchor....why can’t I ?....it’s not fair !’
Take home the anchor first....let her see the shininess .....caress the smoothness.....let her appreciate all the love and care you devote to keeping the anchor looking wonderful. She will then come to realize that the boat that gets attached to that anchor must also be spectacular......My wife wants me to buy a boat………no mention of an anchour,so I can slip it in
That’s so meaningful,thanks
I've heard many a story of wives who are reluctant to let hubby buy a boat, but not so many where she wants the boat and he doesn't.My wife wants me to buy a boat………no mention of an anchour,so I can slip it in
Honest guv…….its the choice of anchour that’s holding me back!I've heard many a story of wives who are reluctant to let hubby buy a boat, but not so many where she wants the boat and he doesn't.
Yes, we've heard all your protestations about how much you want one, but actions speak louder than words. Methinks the Wansy doth protest too much
Yes, but what about the anchorMy wife wants me to buy a boat………no mention of an anchour,so I can slip it in
Luckily she is quite happy to sit in the cockpit so won’t get up the front to see the itemYes, but what about the anchor
You’re not Mr Shan in disguise, are you? Your man math has a very similar quality to it.The anchor equipment is always the first thing I overhaul on a boat. I anchor whenever possible and would rather anchor than sit in a marina. This is what I use to justify my investments in ground tackle and accessories - I don't necessarily trust second hand anchors, and one with an extra hole in the shank means a new anchor IMO.
So I did some online comparisons .... a galvanised 25kg Rocna MkII which is a direct competitor can be had in Germany for around €1650 ... going with something else like a Lewmar Epsilon (galvanised) would be about €1000 - Stainless Steel versions of these anchors are all around €3k
So from those 3 - Rocna, Epsilon and Ultra I can only get a saving by going galvanised, and there's nothing in it if they are all stainless steel.
I already have a 10mm SS chain which is gorgeous - I am now a SS chain convert - it drops into the anchor locker like a dream and doesn't bunch or back up at all. It's also very shiny - I've gone over it all quite carefully. I've also renewed the remote, cleaned up the anchor locker, and it's beginning to look really rather well organised and workmanlike.
The chain must have cost the previous owner somewhere in the region of 5K but there is only 50m of it (upgrade 2 in a few years will take that up to 80) ... so why did he skimp on the anchor? I don't know but it needs to be put right.
Now comes the man-maths .... an overnight berth in a marina costs around €90 these days ... so an Ultra is the same price as about a month of overnight marina fees. I intend to keep the boat for at least a decade or more and I'd easily rack up a month in a marina if I had ground tackle I wasn't 100% happy with ..... so I ordered it.
.... and it arrived yesterday, and it's very shiny.

... you can see it hanging from the shank
The wife’s maths is accurate down to six decimal places
Only when you are paying.
