First and foremost, you have to avoid larger vessels that can only travel in a channel. Even if your vessel is operating under the rules otherwise, you must give way to a boat that could potentially run aground or get into a collision if they
left the channel.
Try and operate on the edge of the channel. Be extra cautious if you come to a bend in the waterway, and can't see
traffic coming towards you.
You may sound a prolonged blast as a warning to traffic headed your way.
On the Great Lakes and Western River system, vessels going downstream are stand-on, vessels going up
stream must give-way.
