Which consequence results when a wooden ship's copper sheathing detaches below the waterline?

💡 Explanation

Accelerated galvanic corrosion proceeds rapidly when copper detaches exposing iron because the copper acts as the cathode with a large surface area. The iron therefore corrodes more quickly, rather than increased drag/fouling which has comparatively slower effects.
