← HistoryWhich consequence arises when an 18th-century mariner used uncorrected sextant observations?
A)Greatly inflated reckoned speed
B)Substantial longitudinal position error✓
C)Chronometer spring fracturing prematurely
D)Catastrophic hull planking separation
💡 Explanation
Significant longitudinal error results, because imprecise angular measurements during celestial navigation trigger error propagation during position calculations using the method of lunar distances. Therefore, location is skewed, rather than inflated speed or hull damage.
