Which navigational hazard increases when a marine chronometer aboard an 18th-century vessel experiences persistent errors in rate?

💡 Explanation

When a marine chronometer's timekeeping drifts, accumulated error affects calculating the Greenwich Mean Time difference used for longitude determination because longitude corresponds directly to the east-west difference from Greenwich. Therefore, inaccurate longitude determination results, rather than current errors, celestial errors, or hull damage, which depend on independent factors.
