Which outcome occurs when a ship's hull plating experiences extended immersion in saline water?

💡 Explanation

Exposure to salt water establishes a galvanic cell between different metals in hull plating, starting galvanic corrosion. The more active metal corrodes preferentially because it has a more negative electrochemical potential; therefore, the hull weakens as metal ions dissolve, rather than benefiting from increased rigidity or altered hydrodynamics.
