Most permant anchors
are mushroom types for a reason. Yeah one has to dig them in per say, but once dug in they hold in ALL directions. If I were to use a bruce per say, it would probably be 3 or 4 in some type of pyramid style setup, as they were initially designed this way on Oil rigs
. IE and anchor
or two/three per side of the rig
Again, it seems to come down to proper size/wt etc along with what the design of the anchor
is, vs "just" wt!
