That is an example of a extreme situation that I hope to never be in. In the case of a log jamb like that I would be approaching from down stream and would have one guy running the boat keeping it up to the logs and another on the bow cutting a hole through. The best way is to do it from shore but even then you need a little more reach than a 16" bar provides. When going down stream it is best to hit the brakes, turn around and get the heck away from any log jamb.
