History

Which risk increased for early longships using hemp rope?

A)Seawater biofouling decreased vessel speed
B)Rope-borne pestilence affected coastal populations
C)Rapid water absorption impaired rope stressing resistance
D)Electrical conductivity leaded to corrosion risks

💡 Explanation

Longships utilizing hygroscopic rope were highly affected by mass changes; the mechanism responsible is capillary action driving water uptake from the sea. Water saturation increased the rope weight and diminished breaking strength significantly, because high water lowers hemp´s tensile capacity; therefore saturated lines failed earlier, rather than pestilence or speeding declines.
