Which navigational consequence increases for Viking longships when relying solely on sunstone compasses on overcast days?

💡 Explanation

Cumulative heading error increases because reliance on the birefringence mechanism to estimate the sun leads to drift with each course correction. This compounds over long voyages, therefore significant deviations result from the intended course, rather than degradation or decline in rudder effectiveness.
