I have cruised extensively and spend the majority of the time on the hook. I have anchored in a variety of places with different bottoms and conditions from the
Bahamas to the
Canada.
I have tested many different anchors as well as noting what works and does not work well with other cruisers in adverse situations.
Most anchors work ok in the average scenario. Its the Adverse situation that you may not have faced yet that will tell the true tale of your anchor.
One anchor stands out as being questionable in that adverse situation. When I have been in
anchorages with adverse conditions I will note which
boats have problems and what anchor they are using. The vast majority of the time it is the CQR. I have tried this anchor on several
boats myself and it is not a good choice if you want something to count on in that adverse or unexpected condition.
The CQR is a plow. A plow by design is intended to move through the ground it is entrenched in. The CQR and the other plow designs do this very well. The bigger the plow the more "horses" it takes to move it. No matter how large it is, given enough "horses" you will move it. All the various anchor test out there serve to prove this point. The holding power of a plow type anchor is much lower.
Here is what I have found that works best and its weakness. (There is no perfect boat nor anchor to go on that perfect boat)
The Fortress sets quick and holds extremely well. It out performs
steel Danforth consistently in my tests. It must be set up correctly for your bottom condition. This anchor is not the best to use when you will shift around with
wind and tide. It does not shift well while buried and it may bend the shaft or pop out and foul and it may not reset. I use this anchor as my second anchor on the bow pulpit and use it in Bohemian sets where it will pull straight line all night.
The Super Max is by far the strongest holding anchor I have used. The harder you pull the deeper is goes. I have buried this anchor 15 feet deep in the mud while testing anchors in Charleston SC. It is my third anchor and is my number one
hurricane anchor. I have watched this anchor pivot while under the sand in the
Bahamas in a storm where wind shifted 180 degrees in minutes. It did not pop out. The down side of this anchor is that it is a bit touchy in how you set it. You must have some slight backing momentum when the anchor is being dropped. The other draw back is it needs a soft or sandy bottom. It has such a wide cutting edge it will support itself on hard bottom rather than cut in.
My primary Anchor for the last 4 years is the Rocna. Sets well and holds well and it does not seem to care how I drop it. It works in
grass. It is the best all around anchor I have tested. The down side is that no matter how hard I pull down I cannot bury it past the hoop except in soft fluff mud. But it holds at that point. I have yet to encounter a situation where this anchor is not well suited.
I am very intrigued by the Ultra anchor and by playing with the little models they have at the shows. I just cant see paying the price. Even if this anchor performs as well as it said to, it is not that much better than the Rocna which is a fine performing anchor in it own right. I would like to see them come out with a Galvanized version at a much more competitive price point for me to spring for a "better" anchor.
Hope this is helpful
