← HistoryWhich problem increases when a heavily laden 18th-century sailing ship experiences hogging stress amidships during heavy seas?
A)Rudder jamming due to hull distortion
B)Sailcloth tearing from increased strain
C)Seam leakage caused by plank separation✓
D)Mast breakage resulting from uneven load
💡 Explanation
When a ship experiences hogging stress, longitudinal bending occurs because the wave support is greater at the ends than the middle, leading to tensile stress at the upper midship deck. Therefore, increased seam leakage occurs due to plank separation, rather than rudder jamming, sailcloth tearing or mast breakage which involve different stress distributions.
