History

Which mechanism allowed 18th-century shipwrights to construct larger, more stable wooden sailing vessels for transoceanic voyages?

A)Increased use of iron nails
B)Employing diagonal riders in the hull
C)Adopting steam-powered sawmills
D)Applying copper sheathing below the waterline

💡 Explanation

When spanning immense distances, ships needed increased structural resilience so adopting diagonal riders reinforces the hull by triangulating frame which distributes stress, preventing hogging and sagging due to wave action. Therefore employing diagonal riders results, rather than other options which address different naval concerns like corrosion or tools.
