Which risk increases when a wooden ship hull is constructed using unseasoned timber in 18th century?

💡 Explanation

When unseasoned timber is used, dimensional changes from moisture content occur during service, leading to higher moisture content and increased surface area, which favors fungal growth mechanism that causes rot and decay. Therefore plank rot increased, rather than swelling, splintering, or galvanic corrosion, which require different material properties and electrolytic conditions.
