🔍 Key Concepts

• Catenary effect of a heavy tow line or gear • How weight in the towline affects shock loading in a seaway • Difference between controlling yaw and absorbing shock

💭 Think About

• Ask yourself: What does adding heavy chain to a bridle mainly do to the shape and behavior of the tow line in the water? • Which option describes a general, always‑useful effect of chain weight, regardless of sea direction or vessel behavior? • Consider what problem offshore towing is especially concerned with when the tow is taking heavy seas and jerks come on the line.

✅ Before You Answer

• Identify which choice focuses on weight and curvature of the tow line rather than just directional control of the tow • Check which option describes an effect that directly reduces sudden jerks (shock loads) on the towing gear • Eliminate any answer that mainly talks about convenience of rigging rather than a real seakeeping advantage offshore
