The auto guidance more or less followed the channel, but veered off and I am sure that is because I had a minimum depth that was lower than the intra costal so the guidance was more of a direct route than following the main channel.

We are soon upgrading to a larger boat. So the question is in situations like this is there a default ( I couldn't find one) to have the auto pilot/Garmin follow a mapped channel such as an intra costal waterway or is the way to do it set a min depth high enough that the plotted route will stick to the channel which should be the deepest water?
To me the idea that you would use Auto guidance in unknown waters, or for that matter in a channel, is shocking. And you don't carry binoculars to assist you in navigation? My suggestion is learn how to be a responsible boater before you buy a bigger boat. If that doesn't work for you sell the boat and take up golf.
