In the details...

[Bertil Klevner]

I pimped my 20kg Delta by welding a small sharpened stainless "toth" at the tip
and also added pieces on the lower side of the flukes, following the existing crease in the fluke. Seems the anchor performs better, but i have not made any comparative tests.
The stainless chain seen has not been used. Its purpose is to attach another tandem anchor.

Looks like it would decrease the ability of the anchor to dig in.......

[Bertil Klevner]

On the contrary!
The tip is sharper and has a more acute angle to the seabed. The slightly increased area of the tip also makes the start of the penetration easier. However, I have not like Steve made any measurable test so that remains to be proved...

[thomm225]

Compare it to the new gen anchors which are sharper than the old school anchors and do not have a wide section at the point.....which would cancel out the sharpness

Seems obvious to me but then again we see all sorts of "improvements" on boating equipment and boats by folks that are sometimes hard to understand ...

BUT you might consider why Excel, Mantus, Ronca, CQR, Bruce, and Delta manufacturers never added these sections!?!

Hello, Bertil,

Let us know if you detect any difference with it in the sea beds it is expected to work in. That will really be the test, because if it is noticeably better, you shall have saved yourself a bunch of money and just for the effort of doing it.

Yeah and wider! (at the tip)

I am not going to argue about the benefits or drawbacks of my trying to improve my old Delta, just showing what I've done and my impression of the result. Comparative testing would give the answer, but is not wihtin reach for me.
If You trust the manufactures design and claims, -go for that- but also look at Steves testing and the holding powers and quality of differnt designs...

The "stealth " version!
But seriously, the only thing wrong with a Delta is when the wind reverses, otherwise it's great. I heavily used Delta's on a 47 mono and a 42 Cat throughout the Caribe and not once had a dragging issue in the original direction of set.

I go by results (and my 50 years experience anchoring) which my CQR has given me over the years without the little wide part added to the area that needs to be the most narrow.

Bertil's modifications at least superficially resemble the Excel to some degree. The angled down tip, with a bit of a spade flare to it, and maybe the welded on tabs to the delta's ears resemble the Excel's horizontal fluke surface. But as Steve is intuiting, if the success in in the fine details, and not the broad strokes, then there's no knowing if Bertil's mods do anything positive, without testing.
