Which structural problem emerged in large wooden sailing ships due to the 'hogging' effect?

💡 Explanation

When a long wooden ship experiences 'hogging', the ends deflect downwards, causing tensile stress on the keel amidships because buoyancy distribution along the hull length varies under wave action. Therefore keel fracture results, rather than mast collapse, rudder separation, or plank warping, each requiring different structural weaknesses or environmental factors.
