When backing down, where will the cutter's bow go?

• A. Opposite of the rudder
• B. In the same direction as rudder
• C. No movement
• D. Upward

Answer: (A)

When backing down, the propulsion is in reverse, so the flow past the rudder is reversed compared to moving forward. The rudder still creates a yaw moment, but the direction of that moment is inverted. As a result, the bow moves opposite to the rudder’s direction. So if you deflect the rudder to the left while backing, the bow will swing to the right; deflect to the right, and the bow swings to the left. This opposite response is the key idea to remember.
