The rode is what does the "heavy lifting" by keeping your anchor on the bottom. I'm at 50% length of my boat at 12ft 1/4" SS chain, my wife throws and it sticks, never had an issue!
Exactly this. I have 12' of 5/8" chain. It's heavy as can be, but it does the trick.
Also note... I have a
Manson Supreme: Galvanized Anchor, 15lb., 18' to 25' Boat Length, 20.25"L x 11.75"W x 12"H
Fortress FX-11 with a trimmed stock (so it fits well in the bow anchor locker)
Slide Anchor Large Box Anchor
2x Slide Anchor Large shore spike
The Manson supreme is unreal. But it's a total pig. (heavy, hard to clean, etc) This is very much like the plow style Mantus.
Fortress FX-11 is completely worthless without chain. It's super light, you need to have proper rode and proper scope, but once it sets, it's great. It also cleans extremely easy.
Slide Anchor Large Box Anchor is nice, but like the Manson Supreme, it's a pig. Stupid heavy, and I always get nervous when I get it up to the boat to clean it. Because it's so heavy and big, holding it near the water close enough for me to clean it has me worried that I'm going to bash into my boat and screw up my gelcoat.
Slide Anchor Large Shore Spikes are the best in my opinion. These are my favorite. I had one early on that would get jammed, which sucked until I got it fixed - but other than that, I love using these more than any other anchor... that said... you can't really use these under water ;-).
There are a lot of Mantus fans on this forum and I think there's also a rep/reseller for their product as well. It gets great reviews. I bought my FX-11 before I found out about Mantus and my FX-11 does everything that I want... so I have no reason to look at anything else for that use case at this point.
My testing went: Manson -> FX-11 -> Large Box.
I'm contemplating getting a SS small box anchor just to see if it does what I want... but I am concerned that it's going to be too lightweight for my needs (I guess I could just add 10# of chain to it...).
