← HistoryWhich mechanism limited early 18th-century warships from maintaining high speed in heavy seas?
A)Periodic wetting of the sails
B)Elastic deformation of the hull
C)Torsional flexing of keel structure✓
D)Fatigue fracture of mast supports
💡 Explanation
Torsional flexing occurs because long wooden keels of early warships lacked rigidity; therefore, as waves flexed the hull, speed was reduced rather than by sail wetting, hull deformation or mast support fatigue.
