Underwater Video of the Mantus Anchor Setting

Setting the Mantus anchor at 3:1 in 4.4m. This was the first and only drop filmed in a real anchorage.

Pick a reference point on the bottom such as a small bit of weed and notice how the anchor sets in a short distance. No skipping, no dragging, no fuss. It never remotely looks like it could break out.

Notice how there is not much catenary, even with just the engine power, and how a good anchor can bury despite the chain lifting a considerable angle off the seabed. (A longer scope is always better for both setting and holding. The short scope here is a tough test)

This is how every anchor should set, but very few do.

There is beauty and elegance in the simple single minded purpose of a great anchor burrowing its way beneath the surface that is fascinating to watch. (Someone better send me location of the nearest Anchorholics Anonymous meeting before its too late )

Re: Underwater Video of the Mantus Anchor Setting

I gotta say, there is something about watching an anchor set like that.

Re: Underwater Video of the Mantus Anchor Setting

I have an old Danforth now and am seriously considering a new bow anchor. Watching this video gives me a better understanding of the Mantus. Thank you for sharing!

Can only imagine what it'll bring up off the lakebed where I'm at lol. One is definitely on my to-purchase list soon.

Re: Underwater Video of the Mantus Anchor Setting

Good looking stuff here! So far you've crossed gradual shifts and quick setting off my list. Is it too much to ask for a video simulating a sudden wind shift and showing a pull out and reset from another direction?

Re: Underwater Video of the Mantus Anchor Setting

First Vid looks just like my Excel setting, except the excel usually hits the bottom straight - not at an angle - due to the weight in the toe. And no I don't have any video.

Re: Underwater Video of the Mantus Anchor Setting

Definitely qualifies as boat porn! Good stuff to see various anchors in action. Wish the waters were clearer at my current sailing grounds to do some videos of my 33 lb Bruce.

No its not too much to ask. I plan to produce something like this. Seeing is believing.

I am hoping to do it in a real life situation. I think resetting ability is very underrated. The few tests that have been reported have been under quite artificial conditions (such as pulling with winches one way then the other). The common perception is that anchors tumble break out of the bottom then have to re bury all over again. This does happen. Some anchors develop a very high list as they rotate and these are prone to doing the "breaking out and resetting" as a means of dealing with a significant change of wind direction, but I believe a good anchor, well set, in a reasonable substrate will not (or at least very rarely) do this.

The anchor leaves marks in the sand (see the photos on the anchor setting thread) and its behaviour is reasonably easy to deduce from these marks even if you don't witness the actual rotation.

It is going to be difficult to film. Unfortunately my camera doesn't have a time lapse.I think the best opportunity may be when Med mooring. If the wind is blowing strongly from the stern releasing the stern lines has the effect of giving the anchor a rapid 180 degree change in force. It is still a bit artificial, but at least the wind produces the series of jerks and lulls which I think is part of the difference in behaviour. I have watched this on several occasions and will try to get it on video.

Nice video.
Wish the water was that clear and warm where we are.
