Which mechanism limited Viking longship voyages in winter?

💡 Explanation

Sail icing increases sail mass, applying excessive tension on sheets and causing catenary failure because the support structure reaches its tensile limit. Therefore sails became inoperable rather than by rope failure or hull fracturing since ice loading acted directly on the sail.

• Which risk increases when a deep-draft 18th-century sailing ship experiences significant hogging deformation?
• Which degradation emerges when subsurface groundwater fluctuations affect Mughal pietra dura installations?
• Which error increases when using a sextant without correcting for index error?
• Which data failure occurs when humidity impacts an Inca quipu such that individual knots become indistinguishable?
• A 2nd-century Chinese repeating crossbow's trigger failed after extended combat because rapid firing heated the firing pin, leading to which outcome?
• Which navigational risk increased because 18th-century ship's metal sextant frames experienced thermal distortion at sea?
