I do the same.

The M2 was not impressive. The Rocna Vulcan has set just as well as the M1 or the original roll-bar Rocnas that I've had on 2 previous boats. Never in the last year of hundreds of deployments has it not set in pretty much all bottom types.

Same. One GPS/chart device on at all times, keys in the ignition, windlass on and ready to use, VHF on, and an anchor alarm via one or two methods. Crew members are also trained to observe their surroundings, know how to read the chart plotter while at anchor, and they know that if things look bad to start the engines and move away from whatever is bad

When I leave the boat, an anchor alarm is always on, and can send me a text message if something looks unnatural.

Mantus M2

Im having the same problem and have been in touch with Mantus, They listened to my problems and responded that there is a NEW Shank being
manufactured that will be available in September to solve this issue
of not setting in mud, Waiting for an update to receive my new shank
and keeping my fingers crossed that i don't have to buy another $ 500 buck anchor.

Stevemitchell:
Interesting comparison of those three. I had to eliminate the M1 from my consideration for the same reason (long shank would bonk windlass). Even though expensive (comparatively), I would likely choose the Spade save for the many comments on poor galvanizing (bah).

Southerly:
I don't have a Mantus M2, but I'm always curious about anchors. I was hoping someone who had one would report back after contacting the company. Thanks.

I say, at first, because, after a day of studying, measuring, and thinking, I got my sawz all, and drill out, and with just a tiny bit of modification (lengthening the slot, moving a roller), it fits great now!

I am not quite ready to spend $2400 on a new anchor just now. Not sure it would fit anyway due to the bar on top to prevent the chain from getting caught.

The PO had a S/S plate put on that covers the entire bottom of the pulpit. When I went to a bigger Delta I spent 2 hours with a grinder cutting out the S/S to get it to fit.

I have the original Mantus with roll bar. Mine is 45lb. While I've never been on the hook in really bad wx, I have been through some pretty bad thunderstorms here in FL and my Mantus has always held. I've never dragged anchor and it's set 1st time every time, just like the ads say. I've wondered about the new one.
I do have a question though. I also have the Mantus anchor swivel. I have 150' of 5/16 inch chain. I can't decide if the swivel is a good idea or not. Seems like just adding another possible system failure to a simple system. Thoughts?

My personal opinion is to always try without a swivel, then add one if you determine your setup needs it (due to either a chain twist problem, or having trouble orienting the anchor correctly when it comes into the roller).

The bar on top is not very intrusive, much less so than a Mantus. Expensive? Yes, but sometimes you get what you pay for, but also, piece of mind at night in a blow can be priceless! A long time ago, a USCG instructor taught us, "always buy the best piece of equipment you can find for it's intended purpose". Everyone can argue about one anchor vs. another, but I truly believe that the Ultra is one of the best out there today, so I'm not going to worry about trying to save a few hundred dollars when deciding what I am going to trust my boat to.

The swivel has been debated in other threads. My opinion (we all have them) is that there are some good modern designs that eliminate side loading and are stronger than the chain they are connected to. Low risk that it is a point of failure if you choose the right one and size it properly. If it makes anchoring much easier, well worth it. But I agree, no harm in trying w/o and adding later.

B&blue,
Check your bow roller. Just the roller itself. Is the slot kinda rounded? Shallow? If not (be fussy) go find or make/modify one that is.

Should work when you get it that way. The slot should almost grip the edge of the chain link. When it does the chain will come back up the way it went down.

Thanks Willy, but I have no trouble with the chain coming up. I'll take a look at the roller anyway. Note that I have a combo nylon/chain rode, maybe that helps? Anyway, I also have the Ultra flip swivel so that anchor flips to the correct position 100% of the time. Usually I do everything from the helm with my wife at the bow observing and pointing at the anchor direction. Once up, she clips the cable to secure it and we're done.

See the long recent thread on swivels.

I only used a swivel to solve a specific problem. Your specific situation may depend on why you have a swivel (or not).

The combo rode can be a problem for twist. I've found with mine, it's hit or miss what orientation the chain is in when it first loads after the rope portion comes in.

Mantus 1 and 2

I started out with a M1 but the shank constantly lifted the chain out of the gypsy so I returned it and purchased the M2. This past weekend I learned firsthand how poorly it sets in mud. Fortunately, I ran across this thread on TF! Had no idea that they stopped production of the M2 or the known problem that this anchor presents with setting in mud. I have a email sent to the Mantus representative.

PS Both M1 and M2 were 65lb
