If manila ropes get wet, what happens, and what is preferred?

• A. Shrinks; Nylon or Dacron is preferred
• B. Expands; Steel cable is preferred
• C. Becomes slippery; Cotton rope is preferred
• D. Stays the same; Polypropylene is preferred

Answer: (A)

Moisture changes how Manila rope behaves: when it gets wet, natural fiber ropes tend to shrink and lose some strength, making their load performance unpredictable. That’s why, in wet conditions, a synthetic alternative is preferred. Nylon or Dacron (polyester) ropes don’t suffer the same dramatic shrinkage and generally maintain more stable length and strength when moist, giving you safer, more predictable performance. The other options don’t fit because they describe effects or materials that aren’t the primary concern with wet Manila rope: expansion isn’t the typical issue, steel cable isn’t a rope and isn’t the preferred substitute in many rope-use contexts, slipperiness is a secondary concern, and polypropylene, while moisture-resistant in some ways, doesn’t offer the same balance of strength and stability as nylon or Dacron.
