Q

When towing in an open seaway, it is important to use a towing line __________.

🔍 Key Concepts

• Towing in heavy seas and how waves affect both vessels • Purpose of a catenary (dip) in the towline for shock absorption and control • Relative positions of towing vessel and tow on wave crests and troughs

💭 Think About

• Think about what happens to the tension in the towline if both vessels are not in sync with the waves. • Which towline condition best reduces sudden shock loads and risk of parting the towline in an open seaway? • How does having more or less dip (sag) in the towline change the motion transmitted from the tug to the tow?

✅ Before You Answer

• Consider how a catenary (dip) in the towline affects safety and control in rough water. • Check which choice places the tow and tug in the safest relative positions on the wave pattern, minimizing shock loads. • Eliminate any option that ignores the need for shock absorption in an open seaway.
