I swear this fishermen's story is true.
I was working on a construction crew pouring cement, my buddy had bought a 14ft wooden drift boat and we were going steelhead fishing as soon this pour was over and the job was completed.
We didn?t have an anchor, but I did have a rubber boot that I had worn a hole in the sole of. So I took a piece of 1/2? re-bar bent it into a loop and put it inside the boot then poured the boot full of concrete, stopping 2? inches from the top. The anchor weight the best we could tell was about 15 pounds and the rubber boot protected the boat from the anchor banging against the hull.
The best part was the looks we got from our fellow fishermen. With a drift boat the anchor is hung off the transom using an anchor drop so that the boat can be positioned quickly as you drift into the chosen fishing hole. This being the case the boot dangled a foot off the transom, in plain sight for everyone to admirer. That boot was still hanging from the rear of that boat up to the day it was sold, many years later.
