Which consequence results when a mariner miscalculates longitude due to inaccurate chronometer calibration circa 1780?

💡 Explanation

Inaccurate timekeeping affects determining the Greenwich Mean Time (GMT) which feeds into the longitude calculations using dead reckoning; this inaccurate longitude via dead reckoning affects positional accuracy because incorrect position estimates yield course errors that increase groundings, therefore, collisions become more likely, rather than the options directly related global route planning or compass heading.
