They're OK for certain conditions but I regard them as a special
purpose anchor. They will frequently not set in adverse conditions
such as:

- from a moving boat (anchor planes through water or skips along the
bottom).

- strong currents (see above).

- unfavorable bottom (hard, weedy, rocky, etc).

All danforth type anchors have a strong propensity for becoming fouled
in reversing tide or wind conditions. They excel however in high
holding power for their weight *if* properly set, and if the load
direction does not change more than a small amount.
