Multiple Choice

Polypropylene rope is approximately what percentage lighter than Manila rope?

The weight difference between rope types comes from material density and moisture behavior. Polypropylene is a lightweight synthetic polymer that doesn’t absorb water, so rope made from it stays light. Manila rope is natural fiber and swells with moisture, which adds significant weight. For the same size rope, polypropylene typically weighs about half as much as Manila. So it’s roughly 50% lighter. The other percentages don’t fit typical rope construction differences: 25% would be a smaller gap than usual, while 75% or 100% would imply an unrealistically large or even impossible weight reduction.
