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.
