← HistoryWhich risk increased when 18th-century wooden warships remained at sea for extended deployments?
A)Electrolytic corrosion of copper sheathing
B)Fatigue failure of iron ballast blocks
C)Structural weakening due to shipworm infestation✓
D)Galvanic corrosion from bronze cannons
💡 Explanation
When wooden warships were deployed for long durations, structural weakening from shipworm infestation occurred because the teredo navalis mollusks bored into the hull, compromising its integrity. Therefore infestation resulted in weakness, rather than corrosion which requires dissimilar metals or ballast failure that requires cyclical stresses.
