🔍 Key Concepts

• Catenary in a towline and how it changes in shallow vs deep water • What happens when a towline sags so much that it touches or nears the bottom • Operational risks to both the towline and the tug/tow

💭 Think About

• If the towline hangs down with a big curve in shallow water, what might it physically contact or interact with? • How could bottom contact affect the condition of the hawser and the safety or control of the tow? • Do towing problems in shallow water usually involve just one type of risk, or several acting together?

✅ Before You Answer

• Check how excessive sag of the towline could lead to chafing or damage • Consider the possibility of fouling or snagging on underwater objects or the bottom • Think about whether these separate risks could all occur at the same time in shallow water conditions
