Thanks, everyone for the replies.

He was reading a book about dock building. I would infer he wants to anchor
a floating dock.

Yes, someone read the op. Actually I am thinking about attaching the
pipes of a pipe dock to the cement anchors. I have a hard rock bottom
so I can't auger them in, or let them sink into mud.
I could go the floating dock route, but at the moment I am leaning
to a stationary dock.

Lets make 16 100 lb rubber tire anchors place four on each
corner of a floating dock say 10' x 20'. Do you think it will anchor?

Some of y'all take this stuff (and perhaps yourselves) a little too
seriously don't you?

There are lots of things to consider in an anchor

Doesn't the very use of the word "anchor" mean that the anchor itself
needs to anchor itself to something?

How are you going to anchor the anchor if it's but a block of
something heavy?

Would that a block of something *would* anchor. But of what value is
a block of something sitting on, say, sand, in a 40kt wind?

If, though, the block had flukes to anchor it in place, then there's a
difference, and it might be of some use. Even fluked anchors have
been known to drag in tide and wind - and that's what you're guarding
against - dragging. The physical weight of the thing is far
outweighed by the ability to withstand something trying to move it
sideways, not vertically.....

Your only option in an anchor is the degree of "fluking" required the
locality/s you're going to want to anchor.

You think I'm wrong? Toss a block of concrete the same weight as a
fluked anchor over the side and see how far you drift/drag.....

Home made? Waste of bloody time! And a danger to all concerned...
especially to those striving to rescue you..
