Which risk increases when a wooden sailing ship's hull undergoes cyclical wetting and drying?

💡 Explanation

Material embrittlement accelerates structural failure because repeated moisture changes induce hygrothermal stress. This process degrades the wood's cellular structure, therefore weakening the hull's integrity, rather than causing immediate brittle fracture.
