Which navigation error increased in 18th-century ships when significant wave-induced rolling occurred?

💡 Explanation

Wave-induced rolling made accurate angle measurement impossible, because sextant precision depended on a stable horizon; therefore the sextant readings became unreliable and position calculation uncertain, rather than chronometer drift or declination errors that were generally stable.
