Mantus Anchor Review


Last Updated on September 8, 2019 by Amy

We’ve logged over 30,000 nm on our boat over the past five years, but even with all that sailing, we still have been stationary over 85% of our nights. And most of the time, that’s at anchor with our trusty Mantus Anchor.

Why We Picked Mantus

Since we are small business owners ourselves, we especially are on the lookout for other small businesses that offer a great, innovative product and the service to stand behind it.  And to top it all off, Mantus is a local company, located 5 minutes down the road from us.  After talking to Greg, we purchased the 85lb galvanized steel anchor, which is a size up from the recommended size for the Helia.  Since our windlass can handle the extra weight, we figured that we might as well go large and sleep extra soundly at night.  And talking about service, Greg even came by and delivered the anchor himself!


The anchor can be assembled and disassembled, which is one of the features we liked, but this allows it to come in a relatively compact, wooden box.  That will make shipping the anchor easier than trying to deal with a box large enough to handle the full-size anchor.

Inside the box, the anchor was separated into three main parts, the roll bar, the shank, and the fluke.  Each was securely held down by several zip ties and it was apparent that nothing would be moving around.  Also included were the necessary bolts and lubricant to be used when putting everything together, as well as a universal deck fill lid key.  That was a surprise, but certainly a welcome one.  Instructions are also included, though to be honest, if you can’t figure out how to put these three pieces together, you’ll probably have a tough time dealing with more complex systems on a boat!

Putting everything together was quite easy.  I will admit to being slightly surprised at just how large the anchor was when assembled, though it does look quite nice when it’s all new and shiny.  And it’s certainly heavy!  We definitely won’t be using this anchor for our dinghy, that’s for sure.

In all our nights at anchor, there have been two instances where we had a hard time, both in thick seagrass. Every other time has been wonderful. And we’ve tested our anchor – hard!

It shocks me when the same cruisers frequently have problems with dragging all the time. We’ve rescued plenty of boats mid-drag too!

We are really confident in our Mantus anchor, though. Of course, we usually set our AIS anchor alarm, but it seems that we have a lot fewer issues holding on the first try and dragging than other crusing boats do.

And our anchor has held up really well. The construction is very good; nothing has bent or broken.

  1. Hello David

    Trying to decide between the 85lbs Mantus and the 40kg Rocna for my Lagoon 450s. How do you like the Mantus? Does it fit okay? Would you have gone larger/smaller? Does it really grab the first time every time?

    Any info is welcome
    Enjoy your journey

    1. Hi Steve! We LOVE our Mantus! The 85lb was actually a size up from what Mantus recommended, and while I’m sure that the smaller anchor would have been fine, I’ve never regretted having a huge anchor. It fits perfectly under the trampoline and has only not set the first time twice and that was in soft, soft mud. We’ve seen 40-50 knots at anchor before and haven’t budged.

      I can’t recommend it highly enough. Hope that helps!



    1. Hi Doug! I appreciate your comment and double checked on the Mantus website (http://mantusanchors.com/gallery/ has lots of great pictures) and the roll bar is definitely supposed to hang out over the front of the anchor. We’ve only spent two nights at anchor so far but we’re looking forward to getting more use out of the anchor and spending less time at a dock!
