There are countless examples of how an over reliance of GPS navigation and the electronic charting systems, as well as the use of dead reckoning without a known fixed starting point – instead “eyeballing” the situation – are leading vessels in to danger.
Complacency is like an ever-present bank of fog; it demands some special effort to properly deal with it. Therein lies the problem.
Navigation waste is hazardous waste! It's good to call to mind that GPS is nothing more than an $12+ Billion radio-navigation system that will tell you precisely where you have run aground.
