That would be an example of what I would consider to be "over-reliance"...
After going through the first time, during full daylight, yes, I would make the same passage at night, but keep in mind I would follow my daytime trail that is recorded on the GPS/Plotter. I may be old and somewhat crazy, but after more than a half-century on the water I didn't suddenly become stupid. Now, it it was an emergency, at night, I would make the passage through the reef solely on my GPS/Plotter. Granted, it would be somewhat risky, but not nearly as risky of doing the same passage at night relying solely on paper charts. In that instance, the odds are squarely in favor of the electronics. Essentially, the same chart is on my GPS/Plotter, but with the GPS I know exactly where I am on that chart at all times.
