Photos of Anchors Setting

Bottom is muddy sand with a layer of algae rather than weed.

Once the water warms up I'll venture in with the waterproof compact and get some better pictures.

Oh no! The shaft is already bent!!! Bloody Rocnas.

Funny!

This was a shot from the surface in 10m of water (4.5:1), so it is not enormously clear. The Mantus has set quickly and level, although some of the fluke is still exposed (a bit more than it looks in the photo).

This is not one of its greatest sets, but the big Mantus still has lots of fluke area under the sand, allowing us to leave and explore the island's interior with a hire car. Of course you cannot keep a mermaid away from water so after a long hike to a deserted waterfall, a dip was in order followed by a picnic lunch.

One of the advantages of the best oversized anchor is the confidence to leave the boat unattended at anchor. BTW note the bucket on the bottom. An anchor that catches this sort of debris will never set.

After an overnight sail we dropped our anchor at around midnight in a new spot. The only company was a Greek warship. I did not go over and look at their anchor .

I found out the next morning with the bathyscope that the anchorage is quite weedy, but by good fortune managed to hit a relatively light patch. The marine chart does not list the bottom type and the spot is not listed in any of the pilot books, but modern anchors work in a wide cross section of substrates.

The bottom drops off rapidly. Within less than 1/2 a mile from the beach it is over 80m (250 feet) deep. Anchoring on a downslope has a significant impact on reducing the effective scope, but unfortunately the rapid change means you anchoring close to the shallows with little opportunity to use a long scope if you want a 360 degree swing circle. In the end we settled for 4.5:1 in 10m of water. In the light of day it looks like a good call.

The Mantus has set very nicely. You can see how it has set in less that a metre and sliced through the weed without any problems.


The photos from the surface were very poor so this is from the "dangle under the tender method":

Probably shouldn't do so while at work or with the wife around?

Any pictures of tandems setting (not setting)?

I find the photos on Wemar's web site comical (primary has tripped). In fact, their videos and photos do not show a single success. Funny.




Though I can't take in water pictures here (too muddy), beaches are interesting. In this case, the greater holding of a Guardian lifted it out. It's just an expensive kellet now. It's a good little anchor, just misapplied in this case.




Though it can be done. The nearer is a Mantus, properly applied and it is buried.


But in-water pictures are better (success and failure).

Time for a dip and quick anchor check after my homework. Kobra in 8m at 4:1 good fast set

Wow. Too many posts for one day of looking, so I'll be back. I enjoy diving on other people's anchors. I once even saw a CQR dig in, but since I did not have the camera, it remains an "unconfirmed sighting".

LOL. I'll believe it when I see it.

A neighbour on the quay, who has a CQR, is looking to replace it and took great interest in the Vulcan on my bow. He told me that he'd read somewhere "that CQRs should be removed from boats immediately as they are dangerous and have a tendency to snake and break free."

Now I hasten to point out that this would be considered "hearsay" evidence as I've not seen the comment myself.

Anyway, I passed on my research into anchors and he's been digging around the web himself so I think a NewGen anchor might appear on his bow soon.

45lb Mantus. USVI. Sand and sea grass.

Here's one of the worst sets I've seen on the 25kg Kobra 5:1 in 5m
The seabed here is stated on the chart as a mixture of coral and cobbles. I haven't come across the term cobbles before but it seems to be very hard but possible to dig into. We set the anchor 2 days ago with a bit less reverse thrust than usual, about 2000rpm on both engines for a minute or two. I thought we were in sand and we weren't dragging at all. We've had a bit of breeze, up to 25kn, and there's no sign the anchor has moved at all. I might try reverse at 2400RPM for a couple of minutes and see if it digs any deeper, but as it's been holding well I'm not overly concerned at this stage..

A guess at the problem: one of the cobbles is in the way of the anchor setting more deeply. Maybe more wind would dig it in more, but I think it could also start to drag then. The wind will provide more force on your anchor than your engines, I'm pretty sure.

Thanks for posting a picture of a less than perfect set. I'm eagerly waiting for a chance to start photographing how our anchor sets, but lots of work to do first (haulout jobs with long list.) On edit: actually, do you have any other pics of other people's anchors set in that bottom, for comparison?

No I don't Anne. Actually I just asked Jen to reverse at full revs while I dived on the anchor, hoping to catch it setting with the video camera. A couple of minutes at 3400rpm and it didn't budge, not even a puff of sand. The chain was off the seabed tight right back to the shackle. I guess it's staying put.
