I think that all of the new generation anchors
work much better than the past generation anchors do. They (the new generation anchors) each have their strengths and drawbacks and for sake of this argument they are all within a few percent of each other in overall performance.
You really cannot go wrong selecting any one of them to replace your (insert older gen anchor name here).
I will be doing some
extended cruising in a few years and at that time I will buy 2 Mantus 105# anchors for our
cruise. One will go on the bow roller (replacing an 85# mantus) and the other will be dis-assembled and stored in case we lose the primary anchor. The 85# will be stored as well. I'll get a huge
Fortress for its straight line pull capabilities which will be stored dis-assembled and a much smaller
fortress for side pulls and the like.
That's the plan and I'm sticking by it (for now)
N.B. I sell Mantus anchors on the side and have a bias against Rocna for their checkered past (I've still not gotten over their decision to change to mild
steel and the bent anchors that resulted - fixed now of course).
