I was on the Hoh recently and dropped anchor in a deep tailout that was going to shallow water. Well it quickly brought the boat to a stop and I pulled for 30 seconds and decided to cut the rope. Boat was off balance a bit and I was a BIT scared.

Buddy who is experienced boater made statement that made me feel better. "your not the first guy that's lost an anchor on this river."

I believe my mistake was dropping in deep water assuming I would just bounce till shallow water and eventually stop.
Anyway's I think I dropped over a log and it quickly got stuck. My question is why did the back end not submerge and sink my boat. Only one other person in boat. Not much gear. Buddy said it has to do with scope of line out too. Anyway's just asking.
