It works in mud sand and rock bottoms. I used it only in a small motorboat in sand and mud bottoms with no problem whatsoever, but I guess it would work the same in a small cat.
<br>
<br>There are some facts worth noting:
<br>
<br>1- since no more then two of the four "claws" (is this the right name?) bury simultaneously, its holding strength/weight ratio is worse then that of the better performing anchors - this is not a major concern, in my opinion.
<br>
<br>2 - for the same reason, there is always the risk that the anchor line gets tangled in the other claws in a wind shift, thus releasing the anchor from the bottom, exactly as with the old traditional anchors. For small craft, in temporary anchoring, this is not a big deal. Also, due to the four claws, it buries itself very fast.
<br>
<br>3-It works in rock bottoms, but it can work too well and become jammed. This is a real possibility and it will not bend to be released as a proper rock bottom anchor.
