History

Which limit impacts accuracy when using a sextant aboard a historically-built wooden ship?

A)Hogging and sagging distortion
B)Chronometer's drift accumulation
C)Magnetic compass declination error
D)Atmospheric refraction variance

💡 Explanation

Ships in the 18th century experienced hull deformation. Accuracy suffers because hogging and sagging introduce angular errors into sextant readings, therefore compromising celestial navigation based on observed angles rather than time-based methods or compass issues.
