Which consequence results when an 18th-century mariner miscalculates magnetic declination during celestial navigation?

💡 Explanation

When magnetic declination is miscalculated, the compass bearing will be offset from true north, because magnetic north differs geographically from true north, causing a consistent error in estimated longitude. Therefore, a systematic longitude offset result, rather than random latitude errors, log errors, or ballast failure, which stem from independent mechanisms.
