Which consequence faced Viking longships experiencing prolonged exposure to marine borers?

💡 Explanation

Infestation by marine borers caused structural weakening because bioerosion via organisms destroyed the wooden hull via the mechanism of gradual material degradation; therefore hull integrity decreases, rather than purely affecting stability, fire risk, or sails.

• Which effect occurred inside a Byzantine ship launching Greek Fire, if nozzle blockage allowed excessive fuel vapor buildup before ignition occurred?
• Which instability arises if a medieval motte-and-bailey fortification lacks drainage?
• Which defense declined in effectiveness as trade routes shifted, against the original Byzantine Greek fire?
• Which structural risk during siege increases as a rope bridge's span is lengthened to reach castle walls?
• Which risk increases when Inca agricultural terraces experience excessive rainfall on steep slopes?
• Which risk increases when an 18th-century wooden ship relied solely on caulking rather than frame design for hull integrity?
