Which outcome occurred in 18th-century ship timbers that underwent prolonged cyclical submersion near the waterline?

💡 Explanation

Cyclical submersion induced Moisture Fatigue, because repeated wetting and drying caused wood fibers to expand and contract. This weakened the wood's internal bonds, therefore promoting delamination earlier than continuous submersion, rather than consistently reinforcing the beam.
