← HistoryWhich risk increases for Viking longships when sails experience prolonged saltwater exposure?
A)Faster sailcloth fiber biodegradation✓
B)Increased mast bending moment
C)Overheating of sailmaker palms
D)Reduced hull buoyant force
💡 Explanation
Saltwater accelerates sailcloth biodegradation because delignification weakens cellulose fibers during hygroscopic cycles; therefore, fibers decompose faster rather than bending masts because the sailcloth itself degrades before causing load issues on the spar material.
