History

Which risk increases when pre-industrial square-rigged sails experience prolonged dampness?

A)Rope fiber hydrolysis weakens rigging
B)Sailcloth mildew increases aerodynamic drag
C)Wood rot destabilizing mast support
D)Iron fitting corrosion disabling movement

💡 Explanation

Rope reliant on plant fibers experiences structural failure, because prolonged damp exposure initiates hydrolysis, accelerating the breakdown of cellulose polymers, therefore weakening the rope’s load-bearing capacity, rather than mildew affecting aerodynamic drag if it has minimal mass.
