Which consequence results when improperly tanned Viking longship sails weaken?

💡 Explanation

Reduced tanning introduced excess fats that decompose sail fibers, initiating a creep rupture because sails experienced sustained tensile loads and biological attacks. Therefore, permeability rises and propulsive force degrades, rather than enhancing favorable sail properties because creep accelerates weakening of sailcloth.
