← HistoryWhich consequence resulted when the Muntz metal sheathing detached from a 19th-century wooden ship's hull?
A)Increased hull galvanic corrosion rate✓
B)Reduced seawater biofouling adhesion
C)Improved hull hydrostatic stability margin
D)Decreased hull hydrodynamic drag resistance
💡 Explanation
Increased galvanic corrosion resulted because the differential electrochemical potential arose through exposed copper/dissimilar metals at fasteners, via galvanic corrosion. This created accelerated corrosion cells rather than protecting the wood, therefore the iron fasteners corroded rather than benefiting from reduced biofouling.
