🔍 Key Concepts

• Different synthetic rope materials used in marine towing (e.g., polyester vs. nylon) • Use of wire rope in towing operations • Whether the question is asking for one suitable material or all acceptable materials

💭 Think About

• Think about which of these materials you have actually seen or learned about being used as towing hawsers on commercial vessels. • Ask yourself: are there any safety or strength reasons that would clearly forbid one of these materials from being used as a towing hawser? • Consider whether exam questions on materials often allow for multiple correct options, or whether they tend to group them under a single inclusive choice.

✅ Before You Answer

• Check if polyester rope is recognized as suitable for towing due to low stretch and good strength. • Check if nylon rope is used in towing and what its main characteristics are (e.g., high stretch, shock loading). • Verify whether wire rope is a traditional and still-accepted material for towing hawsers.
