Mantus M1 Anchor 13 lb. Test. Anchor Test Video #72

[@feastures]

Would be nice to see the Mantus M1 and M2 compared under same conditions.

[@barrydavies2977]

I bought a mantus 15kg based on various reviews especially yours. I have to say that I haven't regretted the change from the 20kg delta copy that I had before. It performs superbly. But not perfectly. I sometimes think that the 20kg might have been a better choice. The extra weight will just punch a hole in the surface more easily. I do wonder about the extra thickness at the tip. I know it's because they want extra weight, but I think that the weight is negligible. The thickness is not. I've only had 2 times it has not dug in immediately. By slowing down and doing the job properly it always digs in. Once set, it's like I'm anchored to the quay side. Absolutely immovable. Thanks for the review. Great job as always.

I have 2 17 lb and one 13lb. Yes the 17's work better than the 13. I've never seen any other anchor work as well as the Mantus.

[@andreruegg9490]

Do you have experiences with a SPADE anchor?

[@martyjackson4806]

@@andreruegg9490 Yes. I have been giving them away! Bruce. Danforth. CQR. I'm switching all to Mantus. I have the first version of the Mantus. I'm looking forward to checking out the newest one.

Fantastic work, Steve. You've done us all a great service with this work :thumb:

Great test thank you very much! I agree with your assessment of the size of an anchor affecting how well it works. The density and texture of the bottom and the size of the seaweed and all features of a bottom remain the same no matter what size the anchor is. The bigger and heavier the anchor is the easier it will be to penetrate and dig in. You can take it to an extreme and imagine for example a miniature anchor that weighed a few ounces which of course would be very unlikely to dig in. I used to have a small mantis and was very happy with it especially compared to the Danforth which would jam up with mud and shells and or seaweed and not reset because the flukes would get stuck pointing upwards and the anchor would just continue to drag and not flip over. I confirmed this problem with the Danforth on Mudflats at low tide and it was a regular problem with resetting in both sticky mud and granular sand with rocks and shells as well as seaweed. the Mantis worked great on the same Flats.

Great video, thank you! What’s your top choice for a 20’ 4,000lb boat?

[@andrewgeddes4640]

I love your series. Most instructive. One thing i would take issue with is your FAST reset. Chane of wind/tide does not happen that fast and a perfect example is yr second (slow) reset of the Mantus. I do not think that yr testing with a fast reset actually represents reality. Otherwise a wonderful series. BRAVO !

[@CDNRower99]

Really appreciate your videos and methodology, Hope to see more!

[@MrAthlon4800]

I do wonder if drilling holes or slots into the anchor blade would prevent fouling and improve reset performance? Maybe worth testing this out, I suspect it would help, especially with smaller anchors that are more prone to fouling...

[@crunchycrispybacon]

It’s well known that these anchors hold well over other traditional types but it also seems like they are harder to pull up. Any way you can test and show the results of which ones are easier to pull out of the mud or sand? I would almost rather give up some holding power and gain ease of pulling the anchor out. nothing worse than a stuck anchor

[@flygoodwin]

I have not measured the (vertical) force needed to dislodge anchors from the seabed. That said, my feeling is that retrieval force correlates very well with a proportion of setting/holding force, regardless of anchor design.

[@ThatBeardedVeteran]

Just bought my fist boat (23’ Essex performance boat). Been struggling with my first dansforth with 10’ of chain in AZ lake bottoms. Ended up losing it this weekend (rookie mistake). Was already in the market looking for a better option. All other Mantus videos seem to be filmed by Mantus cult members lol by purposely not letting competitors set. I watched you big 40 min anchor video and would like to see if there is any change to these “smaller” versions. Would also like to see a box anchor added into the mix if possible. Thanks for all the great work!

[@dontpanic4694]

Geeze... you're still at it! Thanks, really appreciate all your effort!

[@fugue137]

At 7:21 you say "that was completely unrealistic". I love your testing methodology for just this reason: where I live the wind usually changes pretty gradually, but I've seen one or two squalls where it can reverse and build to 25 knots in under a minute, and I think you've seen much worse. And then there's the upper Bay of Fundy tidal bore ;) Why is this flip completely unrealistic for simulating those kinds of events? Also, an anchor is an invaluable safety tool and should be able to set if dropped from a fast-moving boat, but I guess you'd assume no mud buildup in that case. Anyway, this is fantastic---as far as I know you're the only person doing systematic testing of anchors under real-world conditions rather than kowtowing to the anchor manufacturers' line of "please only test our anchors in laboratory conditions". Please keep it up!

[@fugue137]

Also, stainless cleans up easier than galvanised. I'd love to see you try the same anchor in the two materials in the same bottom, and see if there's much difference in fouling. Also also---what if you apply e.g. silicone or teflon lube to the anchor? I'd be wary of the environmental risks, but of course there are also environmental risks to having an anchor drag (or anything else), so balance...

[@hanfordcreek5309]

Is it possible that the drag of the bridle you have attached to the bar is inducing a moment that detracts from the points ability to dig in?

[@flygoodwin]

I believe this is a negligible factor. The scale of the camera apparatus is quite small: Tethers - 1/8" cord, Camera and Float together are about the size of a fist. Camera buoyancy is 11 oz.

[@hanfordcreek5309]

@@flygoodwin Considering the scale, I think your right.

[@cruisesail4310]

Morning Steve. Thank you again for a great video on anchors. I see your not in Panope. Those little anchors would never get a chance to grab on her. I see that Panope has large windows. I am interested in the glass used. I have large windows on my boat and I need to do some replacement work. Only way I could find you is through KZbin. Boat is not far from you, in Everett. Your insight would be helpful.

[@flygoodwin]

Thanks, Cruise Sail For the pilot house windows, I used 1/4" tempered glass. I had these custom cut at a local glass company. Note: I made no attempt to achieve an "ocean standard" as I do not intend to cross oceans. Thicker glass might be needed to withstand survival conditions at sea.

[@theislandpackrat]

Great test! I think that's most peoples problems they use to small of anchor!

[@philipdonegan9716]

Is this not a very, very small anchor ? I mean would people realistically use such a small anchor?

[@flygoodwin]

This anchor belongs to a friend who has used it extensively and with success on a very light weight, 32 foot catamaran.

[@feastures]

As always, great video; thanks! In addition to scope one must also specify depth + height-of-anchor-roller because an anchor rode follows the catenary curve. A scope alone doesn't say much at all! This leads to very common anchoring failures. This is well explained here: kzbin.info/www/bejne/fICuh4Jpf6eaers

[@at1cvb417]

depth + height-of-anchor-roller is scope. 3x scope is 3x the depth plus the height of the anchor roller....The only variable assuming your not taking on water is the depth so saying scope does in fact take in to account the only variable depth.

[@flygoodwin]

Height of anchor attach point (above water) was considered when calculating the scope(s) depicted in this test.

[@MrAthlon4800]

You really should repeat the test by swapping around the roll bar and fluke so that you turn your mantus from a concave into a convex anchor and see if the mud stays attached and fouls anchor or not....

[@sailingcitrinesunset4065]

3:1 Scope is unrealistic for any anchor
