Ever run aground? SURE
Have I ever run aground? Sure. Lake Winnebago is basically a VERY WIDE spot in the Fox River in NE Wisconsin (6x30 miles, max. depth 35'). There are any number of reefs and bars.
The second time I ran aground was on my San Juan 21. After reading on the owners' website about the horrors of not pinning down the swing keel, I locked it down and promptly hit a shallow area. The Admiral didn't like the fact that we were leaning over about 20 degrees, or that I had to lean out at the end of the boom get the keel off the bottom. After that, I only pinned down the keel when the winds picked up. I also bought a depth finder as the charts aren't always accurate.
The first time I ran aground was when I worked at a marina near the mouth of the Fox River. It was the end of October, we had to move all the boats from the Pioneer Marina around the point and into the river. Since there was a drawbridge what we needed to signal and it was 40 degrees out, I kept the hand held freon horn inside my jacket with the bell pointed down toward the upper part of my leg.
Each time I moved a boat into the river, I cut the corner a little closer, until on one trip I ran aground in the silt. When the boat stopped, I didn't.
As I went forward, I hit the button on the freon horn, which set it off. The cold freon almost froze my @#@%* off. It took several months for the freeze scar to go away.
