“Okay,” I said, “I’m gonna try the engine again, I have an idea.” I powered forward, turning our big, well-protected rudder from one side to the other. I imagined our keel twisting back and forth, carving a hole in the bottom. It soon seemed to make a difference and our swing radius continued to increase. As we gained more motion, I added reverse to the repertoire. Ten minutes after running aground, we were free, once again heading 10 miles up the Columbia River on our way to Astoria, Oregon.
