🔍 Key Concepts

• How a tug’s position affects its leverage on a ship’s heading • Difference between towing ahead vs. pushing or pulling on the side/quarter • Where a tug has the least turning moment on a vessel’s hull

💭 Think About

• Imagine the ship’s pivot point when moving ahead and ask: from which position can a tug best twist or turn the ship’s heading? • For each option, picture the line of pull: is it mostly straight ahead/astern, or does it give a sideways force that creates a turn? • Which position would mostly just help with pulling or braking the vessel, rather than actually steering it?

✅ Before You Answer

• For each choice, sketch the tug’s position relative to the vessel’s pivot point and center of lateral resistance • Check which arrangement gives minimal turning moment (torque) on the vessel • Identify which setup mainly affects speed and track but not the ability to change heading effectively
