Hi folks.,
I'm looking to get a better primary anchor and shift my 8# Danforth onto stern duty. Various threads have spoken highly of both box and mantus anchors and I'm interested in hearing if there is a preference between these two. I have a 23 ft four winns bow rider that weighs 3800 lbs. Thanks for any input. Sent from my SAMSUNG-SM-G920A using Winnipesaukee Forum mobile app |

I conducted a TON of research on anchors a few years back and was down to these same two. I ended up with a Mantus because I didn't like the weight, potential collapsibility, and some reports of the eye loop breaking on the box anchor. Since then, a bunch of my friends have gone to Mantus with equal success. For example, on Sunday we anchored in a stiff breeze and were the only boat of 4 near us that didn't drift or have to reset. In fact, two boats were continuously drifting and resetting to the point that we went to them on our way out to discuss anchoring (and, of course, Mantus).
That being said, box anchors, as well as Digger (ishoot308 will be by soon) and Fortress all get good reviews. I'll be sticking with my Mantus 8 pound, though, as it's been two years without a hiccup. Sent from my Moto G (5S) Plus using Tapatalk |

Also does anyone have an opinion on the fortress anchors that Parafunalia sells? Those would fit better in the compartment. I had a box anchor for my last boat. It was great for holding but a serious pain in the butt fold and unfold. Thanks |

I remember thinkxingu's exhaustive research on this …………. but I have to tell you around the same timeframe we moved to the Fortress ( available at Parafunalia) and it has been SUPERB.
It is quite an amazing anchor - it is as light as a feather ( which my wife loves). When you first lift it, you would swear it would not hold a 6' skiff. We have only about 3' of chain leader and this thing grabs first time/ every time & holds steady in the roughest of "sandbar" conditions ---- no more slipping & resetting! In deep water settings (Fall when the water is not swimmable), we have held other 26 to 32 footers "rafted to us" with ours being the sole anchor ! One trick we have learned with the Fortress -- as it is so lightweight, when dropping anchor in deeper bow waters - allow it a few seconds to "float" to the bottom (10-15 seconds) before reversing into position. It DOES NOT drop like a normal dead weighted anchor. We have a 26' Crownline Bowrider .

The 8# holds our 20' pontoon with the bimini up in a fairly stiff wind. I think 22' would be the largest I'd use an 8# for, but not in heavy wind/chop.
As mentioned in my original response, Fortress gets very good reviews--between Mantus, Digger, box (the brand with the best history is Slide), and Fortress, you can't really go wrong. Why I chose Mantus over Digger was no mechanics (the Digger has a ratcheting mechanism); why I chose Mantus over Fortress was that there were a fair amount of reviews that mentioned slower/less reliable setting and issues sliding/not resetting when swinging. With our bimini up, we can swing quite a bit. Quote:

I have a Mantus and love it. It's stuck every time I have deployed it.
I have never tried a box anchor, so I can't compare the two.

Box anchor for me! I've held 3 large boats off mine at the same time with no problems. Only thing I don't like is when you are pulling it up it most likely will be loaded with silt and will weigh a ton. You have to dip it multiple times in the water to clean it off. This can be a pain if your trying to pull anchor and get under way when it's windy and trying not to get blown into something or someone. If this happens, I usually will just bring it up to where it is just below the bow and dragging in the water. I'll idle out to a safe spot and then finish pulling it up. By then it will have cleaned it's self off. The plus side is you don't need a chain for it to work, and it will stow away on a small area when folded up.

Prefer the Bruce anchor...….holds in high winds, never fails to dig in to sand or soft bottom

I REALLY have issue with the use of "Box Anchors" when at certain sandbars ( Margate, Smalls Cove, Silver Sands) as they are such a potential hazard if stepped on !!
And to those who say "look before you step" -- tell that to the little ones. Just one man's opinion !!

The Fortress FX-7 anchor works great for my '08 Sea Ray 240 Sundeck.
It easily fits in the bow locker on an diagonal. The rod is a bit too long to fit positioned traverse to the keel. I use the same anchor in FL on my 220 Sundeck and it holds that one against rougher seas there. The Fortress has two settings for the angle of the flukes. See their website for details on that. Like any anchor, an length of appropriate gauge chain is required. This anchor is so light that my chain is heavier than the anchor. |

I bought The Digger anchor based on Dan’s (ishoot308) experience and haven’t looked back...or had to reset anchor either.
At some point I’ll have a small Mantus for the stern while at sand bars. |

It might be old fashioned and a bit heavy, but I've always had good luck with a Navy anchor. It holds the 26' Formula just fine if I do my part and obtain proper scope. Out of the two you mentioned though, I'd go with the Mantus.
My experience with anchors is that the scope can be more important than the design itself - any of the "claw" anchor designs are going to skip along the bottom if your line is straight up and down. |

Thanks for the responses. I will look into the fortress anchor now as well. My wife is the one frequently pulling up the anchor and I do not think she will like the weight of a loaded box anchor.
How do the fortress or mantus handle some of the rocker anchor sites? Sent from my SAMSUNG-SM-G920A using Winnipesaukee Forum mobile app |

Not sure how much research you want to do, but here's one of the videos I watched when I was on my quest: https://youtu.be/l59f-OjWoq0 In the last ten minutes or so, he goes into which he would keep and why. (For those not wanting to watch, he keeps the Fortress as a stern/rowable anchor and a spade for his bow. He does admit his choice is subjective, though, as the Mantus is the "fastest and most reliable setting anchor maybe in the world" but that it doesn't "look beefy enough" and the spade "matches the curves on [his] boat.")
As for rocks with the Mantus, I've never had an issue. My guess is it's the same as any anchor with a point/points. Quote:

I do smile watching some boaters dropping the anchor straight down, often without any chain, then letting out a few more feet of rode., and being surprised when the anchor doesn't hold. Dave

Fortress vs Mantus in rocky bottom? I would have to assume they are pretty equivalent (will defer to Thinkxingu) as that becomes a hit or miss situation for ANY anchor …. in my opinion.

Having used a few anchors over the past few years attempting to hold at the Winnisquam sandbar limited no wake zone the box anchor is my choose. Keep in mind it is sand only. It does hold well

I looked at the fortress anchor. Appears very similar to my Danforth but weighs less. I am a little worried where I would stow a mantus on my boat. And my wife will be an unhappy wife pulling up the box (and that's no good). So based on everyone's
input, will probably get a fortress. Thanks for all the info and here's to quick anchor sets and no drift! Sent from my SAMSUNG-SM-G920A using Winnipesaukee Forum mobile app |

If weight is a major issue, it may behoove you to research the Digger.

I bought a mantus 2lb dinghy anchor to test out as a stern anchor, found it to work fantastic, I have it on 50' of what is essentially a ski line, can easily throw it the length of the line, have had it work fantastic setting very fast in a sandy bottom, held the stern of a 28' with a 15mph broad side wind without issue. I would bet an 8lb one would be sufficient as a day anchor for most boats up to 32' or 10,000lbs, even though it is rated for far less

While certainly not being the only "great" anchor out there, I purchased the #8 Mantus (based on praise and research from 'thinkxingu'), at the beginning of last season. We anchor almost every time we go out and after a back down to set it, it never fails to hold. I use 6' of chain and 150' of rode. I usually anchor in 6 to 12 feet and use maybe 1/3 of the rode.

I would have a look at boats that are routinely anchored overnight and see what they use. I've spent a lot of time cruising in areas frequented by live-aboard boaters and Mantus anchors have become extremely popular on cruising boats. They have a great reputation for a reason. Can't say I've ever seen a box anchor or a digger anchor on any live-aboard boat. I understand priorities are going to be different between a day-use bowrider and a 50 foot cruiser, but the goal (to stay put) is the same when anchoring. I anchor overnight often and if I ever replace my 22lb Delta (which holds my 6000 lb boat very reliably when it sets, but sometimes lands upside down and won't set), it will be with a 13 or 25 lb Mantus. That said, I recently bought a TIG welder and I am considering the idea of welding a Mantus-style roll bar onto my Delta. It's a stainless steel model, so welding to it would be pretty easy and there would be no need to have it galvanized.
