“What happened to the 90 pound anchor he made for his 14 foot boat?”
You’re conflating a 90 pound bag of concrete with the one or more five to eight pound disposable anchors he made.
It is common for some boaters to make disposable anchors out of used bleach bottles and then cut their lines if the anchor gets caught in a snag.
