Q

Which factor(s) must you consider when making up a towing bridle?

🔍 Key Concepts

• Towing bridle design must safely transmit the towing forces between the tug and tow • The relationship between tow size/shape (like beam) and bridle leg length/angle • How available towing power and tow weight affect strain on the gear

💭 Think About

• Ask yourself: What characteristics of the barge or tow will change the angle and length of each leg of the bridle? • Consider: How does the tug’s pulling power relate to the loads the bridle must be able to handle? • Think about: What happens to bridle tension and safety margin as the tow becomes heavier or harder to move?

✅ Before You Answer

• Verify which listed items directly affect load and angle on the bridle legs • Check which factors determine the safe working load (SWL) needed for bridle wire, shackles, and connection points • Before choosing, ask: Is there any option here that would not reasonably influence bridle strength, length, or angle?
