Notwithstanding any other points of comparison, a properly operating and tuned CRT radar often had sharpness and resolution that would be eye-popping compared to most of what I see today or have seen since, well, the demise of the CRT radars.
On smooth water they could be tuned so finely as to pick up individual seagulls on the surface at 1/4-mile and sometimes even 1/2-mile range.
But I digress. It takes good policy-making and real discipline to not misuse your electronic nav-aids, whether AIS, ECS, ECDIS or whatever. That technically falls primarily to the master but shoreside management should also be both knowledgeable and deeply involved in it since many masters don’t know any better themselves. I’m referring mostly to the limited-tonnage crowd, including myself, though I’m sure that there are masters in the “Master Mariner” club that don’t really have it fully together by a long shot.
From my seat in the peanut gallery what I see is that there is an awful lot just left to chance. That’s poor policy and practice.
