🔍 Key Concepts

• Propeller walk and stern behavior when going astern on a tug • How flanking rudders work when the vessel is backing vs. when it is going ahead • Relationship between main rudder (behind the prop) and flanking rudders (ahead of the prop)

💭 Think About

• When a tug is going astern, where is the water flow strongest: over the main rudder or over the flanking rudders? How does that change their effectiveness? • If you want the stern to move to port while backing, which way do you want the propeller wash to be deflected? • Think about how you would set the rudders to pivot the boat in a tight, confined area while minimizing sideways movement of the bow.

✅ Before You Answer

• Verify which rudders are ahead of the propeller and which are behind the propeller on a typical flanking-rudder tug • Check which rudder surfaces get the most water flow when backing and therefore have the strongest turning effect • Confirm that the rudder orders you choose will move the stern to port, not the bow, when going astern
