When it’s freezing, never switch the trolling motor to the sustained "on" position. If you fall in, you’ll watch the boat drive away as you battle hypothermia. Also, try to avoid fishing in spots where there's a barrier of ice between you and the bank. If for some reason you spill and can't get to the boat, you’ll have a better chance of surviving if you can reach the bank quickly. And last but not least, bring the seats and sit while fishing. I know you may not look as cool as Bill Dance chillin' in the highback chair, but I'd estimate that at least 90% of cold water plunges are taken from the standing position. All it takes is a little direction change on the trolling motor, or your buddy shifting his weight to the other side of the boat, and next thing you know you're in the drink.
