History

Which operational risk grows when a galleon's hull is copper-sheathed in saltwater?

A)Increased osmotic pressure on the hull
B)Accelerated galvanic corrosion of rudder fittings
C)Elevated anaerobic bacteria colonization
D)Augmented hydrodynamic drag at high speed

💡 Explanation

Galvanic corrosion increases because copper is more noble than the iron rudder components, resulting in the copper acting as a cathode causing increased iron oxidation. Therefore, the fittings corrode, rather than the hull itself suffering degradation or increased biofouling.
