Which structural risk was amplified in 18th-century warships due to iron bolt corrosion in timber planking?

💡 Explanation

When iron bolts corroded, galvanic corrosion accelerated wood rot because the iron corrosion products attacked the surrounding timber, weakening its structural integrity. Therefore weakened structural integrity resulted, rather than warping, fire risk, or biofouling which involve different electrochemical or biological processes.
