Looks like they tried to link to a YouTube video about the bow roller but it's not showing up.

Re: Those new fangled Mantus Anchors..Bought One...Why

Perhaps I could share my experiences. I bought one a few seasons ago and got a great deal from them. I wanted a current generation anchor and felt like their anchor was a great buy to replace my old heavy CQR. It is on the end of 250 feet of chain and another 200 of rode.
I anchor in Northern BC. Deep(I have anchored at 60 feet), rocky and often a swift current. When the wind picks up...well you get the picture. I have to be careful and make sure the anchor gets a chance to dig in. In gravels I have seen it perform were others would not, once in a current of over 6 knots. Mud and sand are not a problem. Kelp can be challenging (I usually find it after I am retiving my anchor)
I have had to anchor in spots left my others in the bay because they were "bad". Usually at 0300 while my wife is so sleepy my main concern is that she not fall overboard. It has not let me down in these situations yet.
Now I am a realist. Sure the anchor will drag at times. So will any anchor. But I am happy so far with the Mantus. I would buy it again.

As I think about it, their stainless steal model makes less sense. The bolt holes and mating surfaces are ripe for crevice corrosion, one would think.
I think SS anchors, one piece or multiple, are a bad idea all around but I'm still not seeing this as a problem with the galvanized design. Even if you assume that the clamping force of the four large shank-to-shovel bolts is insufficient to prevent relative motion once the anchor is set, I think at most you'll get a one-time slip of the two parts. The load may be cyclic, but it's also essentially unidirectional and once the clearance is taken up, there's nothing more to give. If this is a big concern, you can just re-torque the bolts after the first use/season/squall and call it good.

Hm, don't know what happened with the hook you got. I bought their chain hook, in stainless steel, and it is beautifully designed and made.

They even sent me their locking plastic piece, which did not exist at the time I bought the hook, free of charge! I did not install it (yet) because it does not fit under the shackle I currently use. I may replace the shackle.

I don't have a Mantus anchor and I don't intend to buy one at this time but my experiences with the company were nothing but positive, both with the quality of the one product I bought from them and with their customer service.

Screwed-in galvanized shackle clevis, of course. It is the first place to grind away the galvanization and corrode, no?
