I've no quibble with
radar. If you're using a
GPS/chartplotter to enter a strange harbor though, by night or by day, you're deluding yourself that you're navigating. billyruffin's last post is a nice summation of how piloting should be done when entering port or working in close quarters. Those
chartplotters, especially those where the
charts are over a year old (90%?), are going to start getting more and more people killed. Visual is real.
Radar is real.
Chartplotters are a cartoon that may or may not be real.
