Last year I picked up a 25 pound mantus anchor off craigslist. I finnally used it on fathers day in 20 knot gusts. IMO the design is very good. It set very deep in the mud. I had a heck of a time getting it up. Should have just run the rode back to a winch and brought it up that way. I am however more confident in the mantus than the danforth i previously used.

I would suspect that the Mantus outweighs the Danforth by 10 lbs. In mud especially, I think that the Danforth will out hold the Mantus if they are of equal weight. Don't misunderstand my assessment, I think your Mantus will be fine but weight is more the differential. Chief

Weight isn't always the main factor--look at how well aluminum Fortress anchors work in independent comparison tests. With adequate scope, an anchor digs into mud or sand based on its shape at least as much as its weight. However, without scope, indeed a block of concrete is best.

One thing that can help break a buried anchor out is maneuvering to a position where the rode is pulling almost vertically but at a slight angle opposite to the angle at which the anchor was set. But sometimes it just takes patience. It's taken me a while to get my Delta up a few times after 36 hours or so on the hook.

it outweighs it by a great deal as it is a fortress, came with the boat. would have liked to maneuver over the anchor, but was just me! ill run it back to the cockpit next time where I can do it all without having to worry about snagging that anchor line.

Dave: I didn't say weight is always the major factor. The Danforth design is its major factor but weight is another consideration, otherwise we would all use an 8 lb anchor!. We don't know how much chain is being used either plus the scope. This is just my assessment of the 2 anchor performances. One test is not a full accessment either. I had one of the fluke aluminum anchors and it didn't perform near as well as an equal size Danforth. I used the aluminum anchor as a lunch hook! I finally gave it away. Chief

probably also the bottom is weedy and the fortress has some issues with it.

Todd: Is your Fortress aluminum or steel? This will be an issue as well if mud AND weeds. Chief

Research online seems to indicate Fortress no longer makes a steel anchor. Sorry to hear that! Chief

boy nothing gets the fires burning better than an anchor discussion! Other sites like cruiser's forums list their largest threads as : anchors, monohull vs multihull, firearms on board. Our biggest is "what did you modify on your boat last week?"

Practical Sailor dedicated three issues to assessing anchors last year. And the comments raged for months after that. Aside from teak coatings, anchors are an especially controversial topic. Just sayin'. I just replaced my 25# Danforth for an exact replica. The old one rusted out ( in spite of it being galvanized). And that's just the lunch hook!

yeah teak coatings. I think weve had some cetol vs varnish vs oil debate here, but it doesn't ever turn to pistols at dawn like other sites.
