Which structural outcome develops along keel planks upon heavy seas?

💡 Explanation

In long wooden ships, hogging arises when buoyancy exceeds weight amidships, initiating tensile stress via longitudinal bending because the keel's ends rise relative to its center. This compresses upper structure; therefore hogging strains the keel, rather than the other effects, where racking or sagging concentrate elsewhere under different conditions.
