We test the setting ability of the M2 Mantus Anchor and compare it to the Rocna Vulcan. Both Mantus and the Rocna Anchors weigh 13 lb. The bottom is a compacted hard packed sand.
The anchors are attached to a crossbar so it's easier to visualize the difference in the performance.

The length of chains Benefited the Mantus as it was a longer chain
Shorter chain pulls at a higher angle , pulling it up rather than along
These guys actually sent me additional footage via WeTransfer when I raised doubt/question about the single run shown here. That's pretty amazing and shows they are fair guys. Turns out that their M2 pulls a little harder in all clips. You do see some sand condition differences, so perhaps a swap of anchors might have turned that around, or made the M2 win even more. Anyway, the M2 seems a very good anchor.
The introductory section labels the anchors and appears to differentiate the two anchors by coloring (great speckled vs bright). But in the test the coloring is opposite.
I am a big fan of Mantus products, but this test makes for a good video, it is inconclusive. There are so many factors to take into account. Ground conditions, water saturation, and ground slope are just a few. Also, a statistic of 1 measurement is limited in what can be concluded. To make any comparison, there should be multiple tries swapping anchor arrangements. But even if this is done, conclusions may not transfer to real operating conditions. I better comparison would be something like the one done by SV Panope on RUclips which was not only performed with realistic conditions but also somewhat independent.

The Vulcan anchor (as does the Spade anchor) has a curved down metal rim on the sides of the back half of the fluke which will stop the ears (back side edges) of the fluke sinking into soft bottoms such as mud. The fluke ears of the M2 currently are like a knife in soft bottoms and need some curved down metal rim added around the fluke ears or even simply a fairly large nut and bolt added to each of the fluke ears to prevent them sinking into soft mud bottoms and messing up the setting angle. I fear the M2 anchor would sink on its side into soft mud and drag like or worse than a Delta anchor. Another concern is that mud could accumulate at the back of the anchor and cause weight distribution issues forcing the nose up into the air when resetting - adding slots, fancy cut letters M or drilled holes towards the back of the fluke could address this by breaking suction and allowing mud to fall off more easily. Conclusion: the M2 has at least one design flaw on its fluke that the Vulcan does not have and the M2 might fail in some soft mud bottoms. I hope they correct this because the M2 is an interesting anchor that I might one day be tempted to buy. It has the potential to be better than the Vulcan if small but important alterations are made.
What are other people’s thoughts?
Of course this one of many runs and tets you've done with these two anchors. The fact that only this footage survived, in which the Mantus wins from the Vulcan only slightly part of the time, gives me the feeling that you're hiding the fact that the Vulcan is generally better.
if you are interested we will send you all the raw footage
@@MantusMarine Yes I am interested; I'll reply to your email that introduced the M2. I've spoken with you guys at METSTRADE in Amsterdam and was impressed. I will buy a 20kg anchor this year. It's either going to be Rocna or Mantus; I've ruled out all the others.
@@MantusMarine Thanks for sending me the footage! Turns out that in all clips the Mantus M2 seems to have slightly more holding power. So it's certainly not fake! I did notice though that the sand closer to the water (right next to sand ridges) has a different condition; it's a bit darker and might be slightly looser, yet heavier. So in a scientific/non-biased test, the anchors should have been swapped place. Too bad.
Mantus Marine, I would be interested in seeing the extra footage as well. I am considering purchasing an mantus M2. Is it possible to send me the extra test video footage?
Damp sand? Not the same as real soaked seabed sand. Quite sure not relevant for real holding power?
They are both dragging, try the parking brake.
Also a big fan of Mantus stuff, but I agree there are too many variables for this to be conclusive. And, it's not like the Vulcan does a bad job. Both anchors perform well here.
I have the big (55kg) Vulcan on my trawler and love it - sets hard and fast every time. It's likely the equivalent M2 would perform as well, but I'm not tempted to switch based on this.
Nor would we want you, we also think Vulcan is a good choice
