Which outcome routinely occurred during Viking longship voyages when navigating challenging North Atlantic currents?

💡 Explanation

Significant torsional hull stress occurred because differing wave forces apply uneven pressure along the flexible hull, straining its structural integrity; the induced mechanism is termed 'hogging and sagging'. Hogging/sagging induces torsion, therefore longships were vulnerable to stresses that other craft might withstand, rather than component-specific failures.
