What material is commonly used for whipping and lashing in maritime applications?

Rope yarns are specifically designed for whipping and lashing in maritime applications because of their inherent flexibility and strength. They are typically twisted or braided fibers that can secure and protect other ropes or lines. In the context of maritime use, whipping is the process of binding the end of a rope to prevent fraying, while lashing is used to temporarily or permanently secure items together. Rope yarns are well-suited for these tasks because they possess a sufficient grip and can be easily manipulated to create secure knots.

In contrast, while nylon thread might be durable, it is not traditionally used in the same heavy-duty applications as rope yarns. Wire rope, on the other hand, is commonly used for high-stress applications like towing or lifting, but it does not serve the same purpose as whipping or lashing. Plastic ties, although useful in many situations, lack the characteristics necessary for secure maritime binding and can deteriorate under extreme marine conditions. Thus, rope yarns are the most appropriate choice for these specific maritime responsibilities.
