Contrary to popular belief I’m an old fashion Navigator who learnt how to operate in badly charted areas with few if any working lighthouses or any other markers that could be relied upon {Indonesia and the South Pacific in the 1960’s and early 1970’s) on ships with no electronic “aids to navigation” like Radar, Decca or Loran. You either learnt to do without, or went somewhere else.
I have also frequently expressed dismay at today’s Navigators, who have their head buried behind screens in stead of looking out the window at the real world, or get out of their fully enclosed and heated/air-conditioned bridge to feel the wind in their hair. What is the use of sound signals if nobody can hear them?
I have also complained that they do not have any feel for how the ship behave and the ability to interpret the signals that there are a coastline, island or reef nearby, or detect the signals that the ship is driven too hard,
(I know that is hard on a VLCC or Mega container ship)
That is VERY different from being realistic enough to realize that autonomous ship, with nobody onboard to look for such signs, will be coming, whether you or I like the idea.
