← HistoryWhich problem emerged in early 18th century wooden warships due to persistent hull wetness below the waterline?
A)Increased ballast instability during storms
B)Brittle fracture caused by thermal stress
C)Fungal decay weakening timber structure✓
D)Galvanic corrosion accelerating metal fittings
💡 Explanation
Persistent hull wetness below the waterline promoted fungal wood decay because humidity and temperature accelerated enzymatic breakdown of cellulose within timber. Therefore, fungal decay weakened ship structure, rather than ballast instability, brittle fracture, or galvanic corrosion which involve different contributory environmental or structural factors.
