Hi All:

All the talk about the Rocna anchor started me reading and looking.
There are some very compelling data the Rocna sets fast and holds
well. However, Ive noticed that all the tests Ive seen were all
similar sand type bottoms. Here is my question:

If anchoring in sand bottoms (hard, loose, sand/mud) why would I chose
the Rocna instead of an anchor design specifically for such
conditions; Fortress FX series. In other words, Fortress FX or Rocna?
Which holds best in sand or mud bottoms?

Or is the Rocnca's appeal that it holds adequately in a variety of
bottoms? Say, the better crescent wrench (adjustable spanner for you
Limeys).

FYI-
While cruising about 10 years ago in mexico, I had a fellow cruiser /
scuba diver tell me he was always finding Fortress anchors on the
bottom with broken shanks -- that they held fine. However the shank
is brittle when pulled sideways or twisted and breaks. He would not
use one for that reason. He had no vested interest in any anchor
brand at all.

That *is* a problem with that style of anchor. Even if they don't
break, bending the shank can make the anchor less useful.

Primary problem for me is how easily I've tripped ours out by a wind
shift wrapping the rode around the bar. The modern designs avoid that
frailty.

Another problem is when they get set deeply in the Chesapeake mud. Any
time we got hit by solid wind, much less a squall, it could take a very
long time to get it out in the morning.

I know the feeling but it's actually a good problem to have.

Sounds like the kinda problem Skip needs.

I used to think so, or more properly I was worried that the Spade came
out too easily, but though both anchors have about the same area and
"dive" about the same depth (sometimes several feet into the mud), it
seems the Spade rotates around it's "tail" and presents a smaller area
as it's being pulled up. Though I haven't done side-by-side tests, I
believe the Spade's sharp point penetrates faster and easier, so it's
usually deeper than the Danforth would be.

Probably so, ours usually comes up with a huge mud ball on it,
probably weighing more than the anchor itself. We've got a 1 hp
generator driven high pressure wash down pump and it still takes
several minutes to clean the anchor off when it has been well dug in.
