I grew up w/ DR. The only instruments my dad had on his boat was a
compass and a depth sounder. We explored coastal NE every summer. He made a plotting our course, calculating how long it would take to get to the next bouy and so on a game and the winner got a frozen milkey way bar. We didn't have anyone on board named "Auto" to drive the boat.
That was 50 years ago.
Today sadly most people can't find their way out of the channel w/o their
gps.
Don't get me wrong I love the info modern electronics give me but I treasure those simpler days.
