Well, everyone has their own opinion about anchors and there are alot of threads about this very subject.
What I have gathered is that most people agree that the new generation anchors are superior (Rocna, Manson and the like). Then there is a debate about which of the new gen. anchors are the best.
Myself, I went with a Rocna for my 17'er and it's been perfect although it hasn't been tested in any extreme conditions but I did have one night I was anchored on a grass bottom and it was a steady 25-30 knot wind most of the night. Although I was fairly protected so the waves weren't bad.
Large waves have a lot more effect on if you anchor holds or not. You could be right behind a shallow reef or shoreline and the winds blowing 50+ knots and most anchor will hold.
I'd go with a new generation anchor that is oversized for the boat and get plenty of chain. I have 30' of 3/8" chain on my 13lb Rocna on my little 17'er. With this much overkill I can still haul it aboard myself easily and I can sleep without much fear for dragging.

Have a 60lb Rocna on 3/8 all-chain rode. That is oversized for a 41' boat. When that dude goes down and in, it stays. In fact I had to change my weighing technique and now reel it in, lock it down and motor or sail over it to pull it free. It resets better/faster than any anchor I have ever used, and resetting an anchor naked at O-dark-30 is not conducive to anything fun.
After literally 1/2 a century as a mariner, I've used many anchors. Originally, the common anchor on the West Coast was the Danforth, but as I moved West, the genuine CQR became the standard. For over 30 years I stuck with the CQR; it did the job very very well.
When I read about the "new generation" of anchors, I kinda blew it off, thinking what I have is fine. Then last season, here in the Windward Islands, I began seeing other boats holding in places where the CQR would require resetting a few times. Every skipper I questioned about this replied that he was using a Rocna, and most had switched after many years with the CQR.
Fortune smiled when I was offered a Rocna 88 for 20% of retail, so I bought it; a cheap experiment!
We often dive to check our anchor and in over 6 months of voyaging the Rocna has yet to move a complete anchor length before setting! Period! I'm hooked, pun intentional!

I'm in agreement with the advice so far. Switched from a45 lb CQR to a 55 lb rocna. Would not consider going back.
Yup!

We currently have 2 75# Bruce anchors, 400' of 5/8" chain each. If and when we decide to add an anchor, it will probably be a Manson Supreme. It would probably be a Rocna if they weren't made in China. I just don't trust the steel used in its construction.
We also have a 150# fisherman style anchor with deck davit. We have yet to have occasion to use it...

Before you buy the anchor, make sure it will fit on your roller or what type of roller you will need. The anchor shaft needs to fit into the roller and be kept far enough
away from the bow so it doesn't damage it. A couple of years ago I bought a Manson Supreme but could not adapt it to the boat.

The Manson Supreme is built with a more expensive higher grade of steel than the Rocna. The Manson uses Bisalloy 80 which is what the designer of the Rocna originally INSISTED the Rocna HAD to be made from...
Will a Rocna bend? Probably not but with all the Rocna shenanigans, and the fact that the Manson Is built in NZ with EXPENSIVE NZ labor, and is still competes price wise with the Rocna, which uses cheap Chinese labor and cheap Chinese steel, I too would buy a Manson Supreme.
That said the new owners of Rocna are a reputable and good company. However they still choose to build in China using a lesser steel than Peter Smith, the designer, originally specified for the anchor.....
There is also the USA Made Mantus (USA jobs) which is an excellent product comparable to a Manson or Rocna. I own all three......
Ive got an old 17lb bruce works ok for me. Im sure the newer anchors are probably better
but I have to go by the old adage: If it aint broke dont fix it.

I'd throw the Fortress into the mix. Traditional looking Danforth type design that performs extremely well, and is very light so retrieving is easy.
I cannot fit a Manson or Ronca on my boat without lots of compromises (like storing it below deck), but the Fortress fits the locker just fine, and after a couple seasons of use, I have somewhat jokingly taken to calling it my 'parking brake', because, at least in the bottom conditions we have around here in LIS, it just simply sets and locks into the ground like you tied up to the mooring, every time I've tossed it out, and the very first time. If you have a rocky bottom then you might not see the same results, but in mud clay and silt it is amazing.

The Fortress is a fine anchor. I have a Guardian Fortress as my 3rd anchor. They set very solidly. What they don't have (by design) is weight, and anchor weight is a key element of trouble free anchoring. A heavy anchor doesn't want to bounce, pop-out, and works better on a short scope. It just gives you more options. I pay a lot more attention to my Guardian when using it. If the boat veers 180degrees, I find I have to manually reset it.
And yes, many older bow rollers are not well suited to the shank of a Manson.

Horses for courses. Danforth-type anchors do not reset well when current direction changes. I'm NOT makin' this up. There's SEARCH and then there's research.
I never said it was THE best anchor, I said it was the best anchor that FITS on my boat. As for resetting, the fortress does reset better than most Danforth type anchors simply because it sets so fast. The sharper fluke, large mud palms, and higher fluke angle all work together to make it bite and set faster than any other anchor of that design type.Horses for courses.

Brian, I understand, and do not disagree with you. Danforths are best employed in one directional situations, that's all I was saying.
I have now anchored 3 times with a Mantus 45# . It replaced my 35# Delta. It works great. Each time I anchored, I just stopped the boat into the wind, and dropped in the anchor with limited scope. I made no attempt to set the anchor by backing down. Each time the anchor set the first time in maybe 5' and held. My Hunter 41DS really sails at anchor, but this seems to have set the Mantus even firmer. I am so glad I bought it!
