Which mechanism led to increased hull flexibility in 18th-century longboats when frame scarcity forced variations to construction methods?

💡 Explanation

Reduced planking overlap increased hull flexibility because it decreased the structural rigidity normally provided by overlapping planks working together in tension due to shear deformation, therefore flexibility rose, rather than stiffness increasing from seasoning/thickness.
