🔍 Key Concepts

• Tow positioning of a tug on a barge for maximum control • Difference between pushing, pulling (astern tow), and alongside (hip) tows • How leverage and pivot point affect steering control of a heavy barge

💭 Think About

• In a wide channel, do you need more ability to push, stop, or steer the barge precisely? Which tug position gives you the best combination of all three? • Think about where the tug must be attached to best control the barge’s heading (direction) when going ahead and when backing. • Which arrangement gives the tug the greatest turning moment (lever arm) on the barge without losing control if the barge’s bow starts to swing?

✅ Before You Answer

• Compare which option gives the tug the best leverage on the barge’s center of lateral resistance (roughly near the middle of the barge). • Eliminate any options that would make it hard to check the barge’s head or correct yaw in a strong current. • Focus on which setup makes the tug and barge act most like one maneuverable unit, rather than a long, hard-to-steer tow.
